Wrong path results the python program runs using crontab

Question

I have a script in python under Linux that needs to determine the current working directory. The part of program that does this is:

Click to copy

import os
cwd = os.getcwd()
print cwd

When I run the program it gives me the right answer:

Click to copy

/home/johny/LST/CT

But when I run it using crontab, it gives me this:

Click to copy

/home/johny

Even when I put it in deeper folders, the same path results. Does anybody know what can be the problem?
