You are correct. '%s' is used to convert numbers (or other non-string things) into strings so that they can be used in places where text is required. In the particular case of the print command, this is done automatically so printing a number directly works just fine: >>> a = 123.0 >>> print a 123.0 >>> print 'The size is:', a The size is: 123.0 The '%s' form though allows you to insert the string representation of the number at the appropriate place in the string making it a bid cleaner to read e.g.: >>> radius = 4 >>> pi = 3.1412654 >>> area = pi * radius ** 2 This one: >>> print 'For a circle of radius', radius, 'the area is', area For a circle of radius 4 the area is 50.2602464 is equivalent to this one: >>> print 'For a circle of radius %s the area is %s' % (radius, area) For a circle of radius 4 the area is 50.2602464 If you just want to get the string representation of a number you can just use the str() function: >>> area 50.2602464 >>> str(area) '50.2602464' Oscar ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Oscar has answered your basic question but to add to his comments thee are other reasons for using the %s rather than str() or simply printing the variables directly. The %s allows us to add extra information to control the format of the string produced, for example the total field length and whether it is left or right justified. eg Try >>> "%12s" % "Hello" >>> "%-12s" % "Hello" >>> "%-12.4s" % "Hello" You can read about all the string formatting characters and their 'extras' here: http://www.python.org/doc//current/library/stdtypes.html in Section 6.6.2 Note that in Python 3 this style of string formatting is being deprecated in favour of the new format method of strings (linked on the same page above under the str.format() method) which offers even more options.

In this particular message, your text was pretty easy to extract, but in many cases the html email will become quite garbled by the time the newsreaders pick it up. Besides, it wastes space. The statement, print "For a circle of radius %s the area is %s" % (radius,area) has several areas of interest. Let's decompose it. print - the print statement, which will take whatever expressions it is handed, and convert each to a string before sending them to stdout. In this particular case, there is exactly one expression, and it already is a string. % - the formatting operator, which takes a string on the left side, and a tuple (or other interable) on the right, and combines them together to form a single string. http://docs.python.org/2/library/stdtypes.html#string-formatting-operations "For a circle of radius %s the area is %s" This string contains two %s place-holders. These are not python language syntax, but are clues to the formatting operator that you want a substitution to happen there. So there are two of them, to line up with the two items in the tuple. In this case they are both looking for strings. But %d could have been used to indicate that we want int numbers. And many other combinations could be used, depending on the type of object being used. %08d would mean take the int and left pad it with zeroes till it's 8 characters wide. If you are writing new code, the docs prefer you to use the format method of strings. in this case, the print statement might look something like: print "For a circle of radius {0} the area is {1}".format(radius, area) http://docs.python.org/2/library/stdtypes.html#str.format http://docs.python.org/2/library/string.html#formatstrings -- DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I'm not a python "brainiac" so I apologize in advance if my answer is
lacking I'll try to be as thorough as possible.
In the light of another recent question on here "Where do I start
python" I want to point out there's been tons of linkage to places
where it's rather easy to find the answer what %s %d and %r are
One of my favs is the http://learnpythonthehardway.org/book/ and if
you start from exercise 5 onwards you should get a better idea of all
the print options there are in Python and how to use them efficiently.
If you were inquiring SPECIFICALLY about 'formaters' (the %s,d,i,r
look no further then basic Python manual here:
http://docs.python.org/2/library/stdtypes.html#string-formatting
Lucky for you the %s automatically converts any argument to string
with str() which works for everything in Python, except you might not
like the look of the output.
Be careful to use %i or %d for integers otherwise floats will be rounded up.
Printing strings when using %i will report an error.
I don't think there's any difference between %d (d does NOT stand for
double) and %i.
If you want pretty decimals (1.1) and not floats (1.10001) use the
decimal module.
Else if you were interested in all the ways you can print in python
just look at the learn python link but here's the crash course anyhow.
I don't think you should have any problems if you ever worked in any
of the big c's before.
Printing in Python 3 onwards needs parentheses around the arguments
you're printing, I think for Python <3 following should work:
Basically if in python you want to print string, python can
automatically connect them in a sentence:
print "This"+"is"+"ok"
This is ok
but that won't work if the print arguments are not strings i.e.:
print "This"+"is"+"not" + 6 + "ok"
TypeError: cannot concatenate string and integer objects
and it's also silly to do that, could you imagine explicitly
converting everything to string?
print str(hours)+":"+str(minutes)+":"+str(seconds))
fugly!
What you want to do, resembles the c and c++ printf syntax
print "You can add string %s and number %d like this" %(string, number)
You can add string Banana and number 5 like this
Or also fine, valid only for python>=2.6, and also the way that I
prefer for longer strings is the C# syntax (I think):
print "Something is here: {0}".format(anything)
Something is here: (any number or string)
Because it avoids the necessity for declaring exactly what is it
you're printing and program won't crash, or at least it avoids the
need to add special try catch blocks just for printing. If you see
your output is not what you want you can return and try to work out
exactly what happened.
Hope no serious rules were broken by answering to this question...

[Tutor] Question about Functions
Dear tutors:
The following is an example I found in the Raspberry Pi for Dummies book:
#function test
def theFunction(message):

result=theFunction("this either")
print "reply is: ", result
-
The result of this code looks like this:

I don't get this either
reply is: ARRRGH!

Here's what I don't understand:
When I declare a variable to be equal as the fucntion
(result=theFunction("this either")) is Python also executing the function?
The way I see it, I only called for the function once before printing
ARRRGH!! Then after that I declared a variable and then I print.
This is how I expected the result to look like:

You're not declaring it as equal, that would be `==' (or `is' for identity).
`=' assigns, it doesn't check for equality.

Why do you expect "reply is" to happen on the second line? It clearly only
happens when printing the returned value, not when printing from inside the
function itself:
> def theFunction(message):
> print "I don't get ", message
> return "ARRRGH!"
>

>

The extra spaces are because "," implies one. If you don't want a double space
before the message, remove the trailing space in the string.

Yes, when you do function() it calls the function.
In this case it is calling theFunction with the
string arguments 'this' and 'this either', respectively.

You do not get this output because you do not return the
string with the `message`, you print it immediately and
return "ARRRGH!". "ARRRGH!" then gets bound to the name
`result` which you then print.
If you want the result you specify you should return
"reply is: " + result # where result must be a string
Not sure how to expect to get "ARRRGH!" unless you return that
too. You can return multiple objects but you typically need to
attach it to an object. Lists and tuples are frequently used to
return multiple objects. Some examples are below.
# tuple
return a,b,c
# list (in-line)
return [ a, b, c]
# list (created and all objects added earlier)
list_object = []
for x in xrange(4):
list_object.append( x ) #just an example
return list_object
# as attribute (use when you need to pass state / data handling)
obj = Class()
obj.attribute = [a,b,c]
return obj

I recommend going through some beginner Python tutorials first
to get a grasp of how Python works before you start on a book

Dear tutors:
The following is an example I found in the Raspberry Pi for Dummies book:
#function test
def theFunction(message):
print "I don't get ", message
return "ARRRGH!"
All the code above does is define the function and assign it the name
theFunction (which is a terrible name but we'll ignore that for now!)
It does not execute the function.
theFunction("this")
Any time the function name is followed by parentheses (but not
preceded by def) the function gets executed. So this calls the
function passing in the argument 'this' which results in the
string "I don't get this" being printed. The value 'AARGH!'
is returned but not stored anywhere so is lost.
result=theFunction("this either")
This time the function is executed with the argument 'this either'
passed in and the string "I don't get this either" is printed. Again the
value 'AARGH!' is returned but this time it is assigned to the variable
result.
print "reply is: ", result
This prints the string "reply is: AARGH!"
The result of this code looks like this:
I don't get this
I don't get this either
reply is: ARRRGH!
Which is what I described above.
When I declare a variable to be equal as the fucntion
(result=theFunction("this either")) is Python also executing the
function?
Yes, every time the function name is followed by parentheses
it gets executed (and the return value assigned to any variable
ready to receive it).
The way I see it, I only called for the function once before printing
ARRRGH!! Then after that I declared a variable and then I print.
Wrong. You defined the function once. You called it twice.
Then you printed the return value of the second invocation.
This is how I expected the result to look like:
I don't get this
reply is: I don't get this either
ARRRGH!
The 'I don't get...' line is printed inside the function.
The program outside the function knows nothing about that.
It has no way to access that string. That separation of
what's inside the function from the code outside is a
very important feature of programming and is known as
abstraction, data hiding and encapsulation. (All subtly
different variations on the same theme but very important
in programming). It is this feature that enables us to
write reusable functions that can be inserted into any
program without relying on, or breaking, the surrounding
code.
One final thing to note is that when you are at the
Python interpreter prompt the return value of a function
is always printed. But when executing a script file the
return value is not printed unless the program does it
explicitly using print.
>>> def f():
... print 'this is always printed'
... return "this isn't"
...
>>> f()
this is always printed
"this isn't"
Now if you put the definition of f() in a file called
test.py like this:
def f():
print 'this is always printed'
return "this isn't"
f()
##
and run it, you will only see the first line printed.
The return value has been lost because it was never
explicitly printed out. This difference in behaviour
between the prompt and executing a script often
confuses beginners but is a useful feature when
testing/experimenting at the >>> prompt. You just
need to remember that it will not always give
identical behaviour to a script.

Function in Python work very much the same way like they do in most
programming languages. When working with them you can't really "feel"
the difference.
There is a big difference, however, "underneath" (just always keep in
mind everything in Python is an object, the book should mention that
repeatedly).
Since you didn't mention I have to assume you didn't do any
programming before python.
In the case of big C's (C, C++, C#) I was always thought that I should
look at a function as a variable. In particular the exact same
variable you return.
I.e. if I have a function:
>>> def add1(int_number):
return number+1
you can look at function add1 as if it's an integer because it returns
an integer.
The same applies to your example, which you can see if you do some
introspection:
>>> type(result)
So you see your result is nothing more then a string! Basically
whatever you return in your function will be assigned to the variable
you return it to. Because you return "AARGH" in your function and
assign the return value to result:
>>> result=theFunction("thisEither")
the variable result will become "AARGH". So this line basically amounts to:
>>> result= "AARGH"
This is a special case because this function always returns the same
thing. That's not usually the case with functions.
I.e. let's return to my add1 function. Output (that part behind the
return statement) of add1 function will change depending on the input
number:
>>> add1(3)
4
>>> added = add1(5)
>>> print added
6
What you can also see from the above example is that when I explicitly
assigned a variable to a function [added = add1(5)] the result of the
function did not print out, but the function must have executed
because variable added has a value of '6'.
So function executes every time you call on it, but prints out value
of "return" only when you don't specify a "container" that will hold
it's output.
I'm pretty sure you're confused here because you have a print
statement in your function. Print statement calls on your standard
output that works "over" anything and pretty much "whenever", it's
kind of special that way. If I changed my example function add1 to:
>>> def add1(int_number):
print "Working, hold your horses"
return number+1
then my output from before would be:
>>> add1(3)
Working, hold your horses
4
>>> added = add1(5)
Working, hold your horses
>>> print added
6
This is the main difference between return and print, think of return
like it defaults to print if there is no value to which it can assign
what it returned. That is also why you always see line "I don't get
(this/this either)" printed every time you call on your function.
>>> theFunction("this")
I don't get this
ARRGHHH
>>> result=theFunction("this either")
I don't get this either
>>> print "reply is: ", result
reply is AARGGG
I think it should be pretty clear by now how it works.
On another note apparently ugly with an f in front is a bad word
around here, my apologies I'm fairly new around these places and was
inquiring for your help not even a week ago and don't really know how
things work. But I am willing to help out like you did me, does that
count? Also I'm not a programmer so I imagine analogies when I program
and may be off point sometimes, hope I didn't make too many people
cringe because of that...

Dino

No, you have misunderstood. Equals in programming languages is not the
same as equals in mathematics. Some languages, like Pascal, use :=
instead of = in order to avoid that misunderstanding.
In mathematics, "y = 3*x - 1" declares that y is equal to the equation
on the right, no matter what value x happens to have.
But in programming, instead it *evaluates* the equation on the right,
using the current value of x, and *assigns* the result to y.
So in your example above, result=theFunction("this either"), Python
evaluates the function call theFunction("this either"), collects
whatever result is returned (but not what is printed!), and assigns that
to the variable "result".
Since theFunction prints some things, they will be printed but not
assigned to anything. Only whatever is returned, using the "return"
statement, will be assigned to variable "result".

It might help you to start with a simpler example:
def print_test():
print "Hello World!" # use print("...") in Python 3
This function takes no arguments, and always prints the same thing. It
returns nothing. (To be precise, it returns the special object None, but
don't worry about that.)
py> print_test() # Round brackets calls the function
Hello World!
py> result = print_test()
Hello World!
py> result
py>
So this demonstrates that printing values just prints them. You cannot
access the printed result programatically. It just gets printed to the
screen and that's it.
def return_test():
return "And now for something completely different!"
This function uses return instead of print. Here it is in use:
py> return_test()
'And now for something completely different!'
py> result = return_test()
py> result
'And now for something completely different!'
py> result.upper()
'AND NOW FOR SOMETHING COMPLETELY DIFFERENT!'
So as you can see, using return is *much* more flexible. You can capture
the result of the function, hold of printing it until you want, or
process it further, pass it on to other functions, or so forth.
Finally, let's combine the two:
def test_both():
print "This is immediately printed."
return "And this is returned."
By now you hopefully should be able to predict what calling this
function will do, but just in case you can't:
py> result = test_both()
This is immediately printed.
py> result
'And this is returned.'
py> result.upper()
'AND THIS IS RETURNED.'
