This is a mailing list for learning Python the language, not specific features of individual implementations. Unfortunately, we have a bias here for CPython over Jython, IronPython, PyPy, Stackless, and other even lesser-known versions of Python. This bias is due to familiarity, not because we don't like the other implementations.

Re: [Tutor] Help with Python Program
First off I want to really thank you for all of the help! I am in my
first semester as I started as a non traditional student in January.
Even though I am in an intro class I think that many of my class mates
had more of a c/s foundation in high then I did. It took me a few
tries but I did finally get my program to run using this code :)
#import random target = random.randint(1,100)
import random #import random number generator module
target = random.randint(1,100) #generates random number between 1 and 100
guess = float(raw_input('pick a number between 1 and 100'))
while guess != target:
if guess < target: print 'too low'
elif guess > target: print 'too high'
#otherwise guess == target and game is over
I am having trouble getting it to run for more than one game but am
trying. Also I started off using the idle shell to write the codes but
it wont let you run it from there, so I opened a new window and
retyped it for my first few attempts. I am unsure why you would use
the idle shell if you would need to open a new window and retype it
anyway. Is there an easier way or something that I am not getting?
After doing that several times I just opened a new window and started
from there without using the shell and it worked fine, so can I always
do it that way and not use the shell at all? I am also still kind of
unsure about the loops and was hoping you could explain a little more
about it or may know of a good online resource? Thanks again for all
the help...Steve really helped by explaining it simply to me and I
really appreciate it! It took me like 10-15 tries but I was so excited
when I finally got it to run!

The shell is for testing out things; it's not really for writing
entire programs in. But as a test-tool it's priceless. Don't know what
random.randint() does? Use the shell to find out. Want to see if you
can convert ints to floats? Use the shell. It's a great way to test
short things like that, because it will give you instant feedback. You
can write longer code in it, but it can be cumbersome. In the end,
it's another tool for your belt, I guess you could say.

The while loop you're using tests for one thing: is guess == target.
If it isn't, the contents of the while loop executes. I should note
that while your loop works, it doesn't work as intended: what happens
if you guess too low? Let's see how the program runs:
computer picks a number between 1 and 100 and stores it in variable 'target'
computer then asks user for a number between 1 and 100 and stores it
in variable 'guess'
while loop checks whether guess is the same as target.
If it's not, it checks if the guess is higher than target or lower
than target and then prints the corresponding response.
the while loop checks again if guess == target. It's not, since we
never change the value of guess.
It checks if the guess is higher than target or lower than target...(etc)
the while loop checks again...
In short, you can say that the loop is named because of its behaviour:
it loops until it shouldn't any longer.
I'm sure you can see the problem here. So, while you now can check
whether a variable is equal to another variable, you currently have no
way to change 'guess' for a new try. Can you think of any way to solve
that?
And while this might not be entirely on topic, there's a wonderful
book for complete beginners -- I've used it as well -- that I'd like
to recommend: Python Programming for the Absolute Beginner. In fact,
one of the excercises happen to be this particular game.

[Tutor] roman to arabic
Hi
I just wrote python code to convert roman to arabic numerals, but its not
working.
Can you just check where the problem is and way to correct that.
So here is my python code
import string
print "Welcome to the numeric conversion program"
print "Please enter command"
data=raw_input()
now = 0
previous = 0
total = 0
if data == "r":
print "Enter roman numeric to convert in arabic"
roman_numeric=string.swapcase(raw_input("Enter the Roman Numeral to convert
to arabic"))
if roman_numeric == ("M" or "D" or "L" or "C" or "L" or "X" or "V" or
"I"):
Length = len(roman_numeric) - 1
i = roman_numeric[Length]
if i == "M":
now = 1000
if i == "D":
now = 500
if i == "C":
now = 100
if i == "L":
now = 50
if i == "X":
now = 10
if i == "V":
now = 5
if i == "I":
now = 1
acc = now
if (previous >= now):
total += acc-prvious
print "The total is",total
if (previous <= now):
total += acc-prevous
print "The total is",total
else :
if data == "a" :
print "Arabic number to
convert"
thanks

I'm sorry but the code is so badly formatted via Thunderbird that it's
pretty much impossible to work out what you intend. Try resending with
the code correctly formatted. Also put print statements into the code
so that you can follow the flow and see what it's doing, then you'll be
able to make some progress yourself.

Is your code really indented like that? A quote worth mentioning here
is: "If you need more than 3 levels of indentation, you're screwed
anyway, and should fix your program." -- Linus Torvalds
Now he was writing w.r.t. C/C++ but the principle holds for Python
also in general -- very highly nested levels of indentation are
indicative of some kind of program problem, and will likely cause you
to conceptually lose control of what the code's supposed to be doing.
Can you please explain in english (pseudocode) your algorithm for
converting a roman numeral string to arabic numbers, with a more
direct explanation of what you've tried and how your solution is not
working from what you're expecting. Then we'll be able to help you
better and will not be left having to guess at how
All that said, apart from the indentation weirdness, a few more
offhand observations: I can see 3 different spellings for "previous"
in the code, which will obviously cause problems. The logic to deal
with smaller numbers preceding larger numbers seem broken (though I've
not looked too closely). The conditions both include equality (>= and
<=) which is likely wrong, the indentation is wrong and both
conditions seem to be doing the same thing, which must likewise be
wrong. (You'd expect there to be some difference in handling the case
when the previous number is smaller that the current number vs when
it's larger...)
HTH,
Walter

Are you using a very old versioon opf python?
If not you should not use string.
The built in string methods can do everything you
want without resorting to string.
print "Welcome to the numeric conversion program"
print "Please enter command"
data=raw_input()
now = 0
previous = 0
total = 0
if data == "r":
print "Enter roman numeric to convert in arabic"
roman_numeric=string.swapcase(raw_input("Enter the Roman Numeral to convert to
arabic"))
Are you sure you want swapcase()? I'd have thought uppercase()
would be more effective given the tests below.
Using built in methods that line becomes:
roman_numeric=raw_input("Enter the Roman Numeral to convert to
arabic").uppercase()
if roman_numeric == ("M" or "D" or "L" or "C" or "L" or "X" or "V" or "I"):
This is just wrong!
The parenthesised list will evaluate to True so you are testing if the
variable is True, which it will be if not empty.
You want:
if roman_numeric in ("M","D","L","C","L","X","V","I"):
Length = len(roman_numeric) - 1
If the variable is one of the items in your list it is only 1 char long
so you re setting Length to zero. Is that what you want?
i = roman_numeric[Length]
If you really want to extract the last digit use a -1 index.
In which case you dshould do the same for the check on valid values...
if i == "M":
now = 1000
if i == "D":
now = 500
Are you sure you want this structure?
It would look a lot neater using elif
if i == "M":
now = 1000
elif i == "D":
now = 500
elif i == "C":
now = 100
But better still would be to use a dictionary:
values = { 'I':1, 'V':5, 'X':10,...'D':500, 'M':1000 }
now = values[i]
acc = now
if (previous>= now):
total += acc-prvious
spelling error in prvious
print "The total is",total
if (previous<= now):
total += acc-prevous
print "The total is",total
else :
This else doesn't line up with any if.
> if data == "a" :
else:
if :
could just be
elif :

[snip] Yuk what a mess.
May I suggest you start with a much simpler program, which is to take a
roman number between 1 and 3 (just i's) and convert that.
First describe how you'd convert the number by hand. Then convert that
process to Python.
Test the program. Fix any problems. Report back to us success or a
problem you don't know how to address. Tell us exactly what went wrong.
(e.g. I entered iii expecting 3 and got 17 or if you get a traceback
post it. For example when I run your program I get:
Traceback ( File "", line 12
if roman_numeric == ("M" or "D" or "L" or "C" or "L" or "X" or "V"
or "I"):
^
IndentationError: unindent does not match any outer indentation level
Then add v (now the number is between 1 and 8).
You will come up with a completely different program! And it will be the
correct one.
Also provide meaningful prompts.
print "Please enter command"
If I was running your program and saw that I'd have to give up since I
have no idea what is expected.
print "Please enter command - r for roman-arabic"
would be much better.
