Why does it return 0?

Mon, 10 Nov 2008 15:13:51 -0700

def countErrors(secret, lettersGuessed, errors):

    if lettersGuessed == "":
        errors = errors + 0  
    else:
        subproblem = lettersGuessed[len(lettersGuessed)-1]
        others = lettersGuessed[0:len(lettersGuessed)-1]
        if subproblem in secret:
            errors = errors + 0
        else:
            errors = errors + 1
        print errors, secret, lettersGuessed, others, subproblem
        countErrors(secret, others, errors)
    return errors        
     
        
        

secret = "guinness"
lettersGuessed = "pnitwzg"
errors = 0
x = countErrors(secret, lettersGuessed, errors)
print x

Here's what it outputs:

0 guinness pnitwzg pnitwz g
1 guinness pnitwz pnitw z
2 guinness pnitw pnit w
3 guinness pnit pni t
3 guinness pni pn i
3 guinness pn p n
4 guinness p p
0

I'm pretty new at this, but this just doesn't seem to make any sense. It does exactly what I want it to, except instead of returning 4, it returns 0.

I'm pretty new to Python and i'm havin troubles

Thu, 23 Oct 2008 17:08:53 -0700

Ok I'm new to python since january. i've read a intro book cover-to-cover and have written some code of my own, but i have a nerve-racking problem thats giving my a headache. I can save a module just fine, but when i try to import it into another program it gives me a syntax error and highlights the middle "5" in the "Python 2.5.5" at the top of the page.

Please assist, what's going on and how can i fix it?

Hi i have a question about the python.

Thu, 02 Oct 2008 06:55:30 -0700

You are required to write a Python program which will solve system of linear equations with 3 unknowns
(to be entered by the user).
Your program should display a menu which will allow the user to choose whether he wants to (1)
coefficients (2) check whether the linear system can be solved using iteration (3) calculate and display the
required results using Gauss-Seidel (4) calculate and display the required results using Gauss-Jacobi
Note that in all cases, the outcomes of the iterations should be displayed. Also if the values of the
unknowns are not converging, your program should stop at the 15th iteration.

Why doesn't the loop work?

Fri, 04 Jul 2008 16:22:36 -0700

Why doesn't the loop in the following code work?

#Finds out what numbers are prime.
primes = [2,3,5,7,11,13,17,19,23]
finish = int(raw_input("What number would you like to check to? "))
start = 24
while start >= finish:
    x = 0
    while start % primes[x] != 0:
        if IndexError:
            break
        else:
            x = x + 1
    else:
        primes.append[start]
    start = start + 1
print primes

When run, it just prints out the default set of primes after taking the number you want the program to check up to.

Help with dir()

Tue, 01 Jul 2008 01:00:38 -0700

I'm new to Python and have the Python Reference Manual Release 2.5.2 as my only guide so far, but here's my problem:

I've got a custom class 'Foo' with two functions - 'hello' and 'goodbye' that just print a string.

I'm assigning the output of the dir() function to a variable and want to then perform a dir() on each index value of the first variable and Python doesn't like it. Here's what I've got:

a = dir()
print dir(a[0])

When I execute this the output is the generic classes and does not include the functions of my custom Foo class at all. Now when I forget about assigning the output of the dir() to an array and just hard code dir(Foo) it works fine, returning my two functions. I've noticed that the problem is related to the compiler reading it as a string or a 'literal' I guess it's called, because the output of these two commands is completely different:

dir(Foo)

and

dir('Foo')

The first output without the quotes being the one I'm trying to get by an array variable of the entire generic dir() function alone.

I've printed out the array for testing purposes and sure enough, index 0 is Foo so it should in theory work.

Is there some kind of pickle method or function I need to perform to make dir(a[0]) work???

Thanks!

List files without extension

Mon, 09 Jun 2008 10:09:39 -0700

I'm fairly new to python, and I am trying to write a script that will write all the files in a directory to a text file, but only write the files that have a certain extension (.avi, .rmvb, .mkv etc.) and only print the filename without the extension. So video.avi would become video in the text file, and text.txt would be ignored completely. So far I have been able to list the directory using os.listdir, and write it to a text file, but haven't been able to show only certain extensions and show only the filename. What would be the best way of doing this?

Is it possible to return a variable and use it...?

Thu, 28 Feb 2008 00:09:56 -0700

Hello all,

Is it possible to return a variable and then use it like the following:

dir exp_1:
    while hen != "*"   
       sum = sum + hen
    return sum

dir exp_2:
   if sum >= total_needed:
     print "Profit can be made."
   else:
     print "Expect a loss."

total_needed = int(raw_input("What is the total eggs needed? "))
hen = int(raw_input("How many eggs did each hen lay? Enter them in 1 by 1 or enter * when done. "))
exp_1
exp_2

If not, then how do I do so?

Thanks,
Nathan P.

"#! /usr/bin/env python" does not work..... help

Wed, 21 Nov 2007 19:08:14 -0700

Hi folks.

I've left this post on devshed as well but I can't get an answer and I'm real stuck.

I am trying to learn Python and I've done quite a bit in the last three weeks in the IDLE environment. However I am now trying to get my programs to execute from the command line in Fedora Linux using #! /usr/bin/env python but I just can't get it to work.

I have env and python in the /usr/bin directory. I have changed the permissions using chmod +x for my file and whenever I try to execute without the python command Bash just reports command not found:

[root@localhost moonshinerat]# mycode.py
bash: mycode.py: command not found
[root@localhost moonshinerat]# mycode
bash: mycode: command not found
[root@localhost moonshinerat]#

I'm at my wits end with this and I'm going to defect to Ruby if I can't get this simple thing to work. Thanks for any solutions guys,

Python vs. C++

Thu, 18 Oct 2007 11:31:25 -0700

I have just posted on my blog the reasons why I think C++ is the one true programming language (I am being slightly tongue in cheek here). I used 10 questions to compare it to other languages. Unfortunately I have not been able to compare it to Python as I don’t have any experience of Python development. Would anyone be willing to score Python for me?

very noob question

Thu, 13 Sep 2007 14:54:12 -0700

hello I just started programming in python today and I am going to make a binary program for the heck of it. but so far I ran into a problem. for some reason it will not print 1. any help would be great thanks "
ps what is the difference from int(raw_input("ajajaj")) to input("aaaa")
I am not done with the program yet

name = raw_input("Please enter your name: ")
print "Hello", name, "Welcome to my Binary Program "
binary = int(raw_input("Please enter a number between 1-255: "))
if binary >= 255:
binary = binary - 128
print "1"

I figure it out but I have another question. here is the code I did to print 1 but I don't understand how it work? any help would be great

name = raw_input("Please enter your name: ")
print "Hello", name, "Welcome to my Binary Program "
binary = int(raw_input("Please enter a number between 1-255: "))
if binary >= 255: binary = binary - 128
print "1"

regarding making an exe for windows

Wed, 13 Jun 2007 07:36:42 -0700

i hav python2.5, matplotlib0.90.1, and py2exe for python 2.5 all on windows... i hav a python program(letsc.py) which uses the matplotlib package... and i want 2 make an exe of it for distribution on other comps... i used py2exe... i wrote a setup.py whose contents are :

from distutils.core import setup
import py2exe
import matplotlib

setup(console=['letsc.py'],
options={
'py2exe': {
'packages' : ['matplotlib', 'pytz'],
}
},
data_files=[matplotlib.get_py2exe_datafiles()])

as per the site http://www.py2exe.org/index.cgi/MatPlotLib]... welll in the command prompt (not >>>) i typed [in the correct directory] "python setup.py py2exe". it gave out a lot of text on the console but finally in the end it displayed "error: can't copy 'F:\Python25\Lib\site-packages\matplotlib\mpl-data\fonts' : does'nt exist or not a regular file" (when actually there is a directory called mpl-data which has 3 subdirectories ... afm, pdfcorefonts and ttf) and the process stops. It creates the usual dist and build folders but there isnt the required exe in the dist folder... any help will be appreciated... thanx a lot
