Between the parentheses should go the variables you use (if any) when
calling the function. For example:
def sayhello():
print "Hello"
You don't have any parameters here, so there's nothing between the brackets
def say(word):
print word
Now there is one parameter, namely word.
def sayboth(word1,word2):
print word1
print word2
Here there are two parameters, word1 and word2.
The number of parameters should be the same as the number of
parameters you use when calling the function:
sayhello()
say("One text")
sayboth("One text","Another text")
There is a much used method to make some of the parameters optional,
but we'll not go into that.
To know what is going wrong with your program, I would have to see the
program (or a simplified version of it that still goes wrong) and
preferably also the exact error message you are getting.

Re: [Tutor] [Fwd: Re: trouble with "if"]
I can't exactly show you the error message anymore, because the program is
now screwed up in so many ways that I can't even get it to do the things it
used to.
It says things like ERROR: Inconsistent indentation detected!
1) Your indentation is outright incorrect (easy to fix), OR
2) Your indentation mixes tabs and spaces. Then it tells me to untabify
everything, which i did and it still gives this message. I've started
completely over with the exact same indentation and that one works.
Oh my gosh this gmail is a fricken crack head... none of this stuff was here
last night. I have no idea what was going on then, but everything you guys
said is right here. The plain text is right next to the Check spelling, the
reply to all is right above send and save now and in the corner near the
little arrow. Well, it's working now.
Ok, so if i have a section of code that is:
answer=(2+3):
print "answer", answer
so for the code above I would put: (I think I would have to have the two
numbers and the addition thing in there wouldn't I; I saw something like
this on Alan's tutorial last night.)
def answer(2,3):
answer=(2+3)
print "answer",answer
That is obviously not right.:
There's an error in your program:
invalid syntax
when it says that it highlights the 2: def answer(2+3):
Ok I think I understand these now. Thanks for the advice. I have this now:
def answer():
print("answer")
answer()
It works too, yay!
Thanks,

Ahahahahaha... I have figured these out beyond comprehension and power.
Wahhaha. It feels good to get something to work correctly. Thanks much
Andre. I don't quite understand the putting of things inside the
parentheses, but I've discovered that I don't really need to, because def
text(): works just fine with everything I've done so far.

Adam,
Glad you are sorting out the gmail---in the long run, plain text will
make this all much easier than what you had before :-)
Your answer function definition above is saying something like this:
make answer the name of a function that takes no parameters, and, when
called, have it execute a print.
This:
> def answer(2,3):
>answer=(2+3)
>print "answer",answer
doesn't work, as you are trying to set the values of the two
parameters to 2 and 3 in the function definition itself. That's not
how parameters work. The definition of a function sets the parameters
up as named `slots' that function calls will give values to. (There
are, as Andre pointed out, more details, but let those aside for now
and focus on the simplest cases.)
This:
def answer():
answer=(2+3)
print "answer",answer
would work, but it isn't much different than the code that did work.
Try this:
def answer(my_first_parameter, my_second_parameter):
value = my_first_parameter + my_second_parameter
print "Answer:\t", value
(I wouldn't use the cumbersome names `my_first_parameter', etc. in
real code, but perhaps they help keeping track of what is going on in
early stages.)
That says, in effect, let answer be a function which takes two
positional parameters, adds them, and prints the result in an
informative way.
>>> answer(40, 2)
Answer: 42
>>> answer("A string", " and another string")
Answer: A string and another string
>>>
These work because the function definition ensures that the first
parameter (40, in the first case above) will, as far as the function
is concerned, be called my_first_parameter. (Likewise for 2 and
my_second_parameter.)
Does that help?

Re: [Tutor] [Fwd: Re: trouble with "if"]
I can't seem to get the type with the parameters to work. I can get
def answer(): to work, but not def
answer(my_first_parameter,my_second_parameter):. I'm not too
concerned, as I haven't yet needed to use that. But, when I use the
parameter type, it runs without error messages, but doesn't display
anything. That's when I'm using your example with my_first_parameter.
But when I use:
def answer(40,2):
answer=40+2
print "Answer:\t", value
answer()
it says:
There's an error in your program:
invalid syntax
and then it highlights the first number between the parentheses, like last time.
OK. New topic temporarily... I just completed a portion of my
radiacir.py program, after much debugging. I still want to add that
error message thing that we discussed eariler, but that's a whole
nother can of worms. So I'm going to attach it. This is very
exciting. Except, I renamed it and now it doesn't work. This
frustrates me. How could something work one second and then not the
next. Oh well, I'll still attach it and if you could help me find the
problem, that would be nice.

Re: [Tutor] [Fwd: Re: trouble with "if"]
Ok I forgot to put some things on the previous one. I discovered a
flaw in my loop. It is not infinite. If you select circle, radius,
enter the radius, circle, radius, enter the radius, then the program
stops. I want it to be able to keep going as many times as needed,
infinitely. So that the user could keep using that segment of the

Re: [Tutor] monitor other running applications with Py
Thanks for the pointers, Alan. It seems perhaps a bit beyond my abilities for now, but something to keep in mind for the future if I get that far. And yes, the legal aspects are worth noting, though rest assured my wish for such a thing is for self-monitoring rather than other-monitoring, though I can see how it could get used nefariously if not cautious.

On Windows you can catch Windows events and messages using some of the raw Win32 API calls from the ctypes module. (I've never used ctypes for anything this low level but it should be possible, I''ve certainly done it in C++ and Delphi on Win 9X). But its messy and fairly deep Windows magic and you will need to spend a fair bit of time experimenting and reading the docs on MSDN as well as the Win32 API help file. > Ideally I'd like a cross-platforms approach I doubt if that's possible except at the process monitoring level. For the kind of detail you want the bgestb you can do is have a common UI and pluggable modules based on the OS. Also beware legal implications. There are issues around personal privacy, data proptection etc and these vary between countries (and even states in the US). People are increasingly wary of Big Brother style monitoring. Detecting inappropriate use of the internet across a corporate firwall is generally considered OK but silently monitoring individuals brings you into murky legal waters.

Re: [Tutor] [Fwd: Re: trouble with "if"]
Once again this is my latest version. I know of several problems,
such as the previously posted infinite looping problem. Also, if
sends you to the wrong place sometimes. Ex: a second ago, I pressed
4 to exit (which does not work either) and it took me to triangle.
I'm not sure how to end the program. It takes you to the def
goodbye(): part, but then if you press enter again, it starts the
program over. I was hoping that if I just left it blank, then it
would just automatically end, like it does with simpler programs, but
that was not the case, because apparently there has to be something
after the
def goodbye():
So If someone wouldn't mind taking a look at it, then I would be very grateful.
Thanks,
Au

enter the radius, circle, radius, enter the radius, then the program

infinitely. So that the user could keep using that segment of the
program over and over again, without having to restart the program.
Is it possible to do that?

Re: [Tutor] [Fwd: Re: trouble with "if"]
Hi Adam
> flaw in my loop. It is not infinite.
In fact you don't have a loop, your program
is really just a simple sequence.
#Welcome screen:
def welcome():
print "Welcome to the Area Calculation Program."
print
welcome()
AG:Since you only call this once there is no point in putting
AG: it in a functuion
#Shape choice:
def shape():
print "Choose a Shape:"
print "1 Circle"
print "2 Square"
print "3 Triangle"
print "4 Exit"
print
shape()
AG: And you call this here and again at the end of the code.
AG: But its not in a loop, its just two calls to the same function.
#If circle:
def circle():
shape=raw_input(">")
if shape in["1","circle"]:
print "1 Radius"
print "2 Diameter"
print "3 Circumference"
print "4 Area"
print
circle()
AG: And this gets a string fom the user and prints one of the
AG: values but doesn't do anything with it. Functions should
AG: normally do more than just print some values.
AG: You never use the menu you print.
#If radius:
def radius():
radius=int(raw_input("Enter Radius:"))
diameter=(radius*2)
circumference=(diameter*3.14)
area=(radius**2*3.14)
print "Diameter",diameter
print "Circumference",circumference
print "Area",area
print
print
def choice():
given=raw_input(">")
if given in["1","radius"]:
radius()
choice()
AG: Now you call radius which actually does some work
shape()
choice()
AG: Then you call shape but don't use the result then call
AG: choice which only works for circles.
AG:If we use the more conventional approach of defining the
AG: functins first then calling them at the end your code
AG: looks like this:
welcome()
shape()
circle()
choice() #--> which calls radius()
shape()
choice()
As you see there is no loop just a sequence of function calls.
Now if I rename your functions to reflect what theyactually do:
printWelcomeMessage()
printShapeMenu()
getShapeAndIfCirclePrintCircleParameterNames()
getParameterAndIfRadiuscallRadius()
-> getRadiusCalculateResultsAndPrintThem()
printShapeMenu()
getParameterAndIfRadiuscallRadius()
-> getRadiusCalculateResultsAndPrintThem()
Hopefully this illustrates several things:
1) Naming your functions to reflect what they actually do
helps see what the code does
2) Especially if you group the function calls together at the
end of your program
3) Your functions are mixing up the presentation of menus
and the getting of values.
A better structure might be to do something like:
shape = 0 # a variable to store the shape
printWelcomeMessage()
printShapeMenuAndGetValue() #---store he result in the shape variable
if shape in['1','circle']:
doAllCircleStuff()
else: print "Only circles supported for now!"
And then its easy to wrap that in a real loop
shape = 0 # a variable to store the shape
printWelcomeMessage()
while shape == 0:
printShapeMenuAndGetValue() #---store he result in the shape
variable
if shape in['1','circle']:
doAllCircleStuff()
shape = 0 # reset shape back to zero
else: print "Only circles supported for now!"
Can you rewrite your functions to match that? You need to change
the shape() function so that it sets the shape global variable to the
value input by the user. You will need to include the statement
global shape at the top of the function for that to work. The other
(and better) way is to use the return statement to return the value.
BTW I'm not really suggesting you use those long names,
they were just to point out what the functions were really doing!
HTH,
Alan G.
