newbie to python

[exter_c]

Hello,

How do I find out what modules have been included in my python install?
I am having issues with crypt functions not working on ubuntu or redhat
but they work on Slackware.

Any assistance would be great.

Regards,

Johhny.

How do I find out what modules have been included in my python install?

Look in site-packages directory

I am having issues with crypt functions not working on ubuntu or redhat
but they work on Slackware.

Crypt functions? Are u missing python2.x-crypto package?

Hello,

If I go into the python shell and type help("modules") It does show
that crypt is there. However Im unsure if that means that there is help
or its got the module installed.

From a dpkg --list python* I have

ii python2.4-crypto
2.0+dp1-2ubuntu1 cryptographic
algorithms and protocols for Python

Which means it should work. However Im not really getting anything from
it. Which makes me wonder.

So, what's not working?

Hello,

Here is the script then the problem.

cat testing.py

import crypt
import random, string
def getsalt(chars = string.letters + string.digits):
return random.choice(chars) + random.choice(chars)
username = raw_input('password : ')
print crypt.crypt(username,getsalt())


python testing.py
password : testing
Traceback (most recent call last):
File "testing.py", line 1, in ?
import crypt
File "/home/testing/scripts/crypt.py", line 4, in ?
TypeError: 'module' object is not callable

Read carefully. You have a file /home/testing/scripts/crypt.py which is
imported instead of the crypt module in Python's standard library.
Rename /home/testing/scripts/crypt.py to something else, delete
/home/testing/scripts/crypt.pyc, and all should be well.

Thankyou, I appreciate your help. I did not realise that python would
behave that way.
