you can use regex if you want.It gives you power to do text processing.OO will give you benefit because your program becomes clearer while it is developedCheers,pujo

Hi.
I'm processing a tab-delimited text file where I read in a file,
perform a bunch of operations on the items, and then write them out
again to a fixed-width text file.
I've been doing this with a very functional approach:
- loop over lines
- read line into dictionary
- process dictionary

I'm thinking that perhaps allowing him to run idle and exporting X

To be able to understand why is the crash, take a look at what the

Thank you for including the "traceback" message in your 2nd post.
Index error means you tried to reference an element of a sequence
that is not there. a is the empty string when you just h
I'm guessing when you did that, you got something like an IndexError.
That's because you didn't check the length of "a" from raw_input and
accessed a nonexistent array element (a string is an array of
characters). So if you changed the line:
elif a[0] == '-' and a[1:].isdigit():
to :
elif len(a) >

Hi Vincent,
What do you mean by "crash"? Do you get an error message? If so, can you
show us?
It will also help to think to try playing the situation out without
preconceptions. In the beginning of the loop, a
Hi all,
I'm puzzled (:-))
Why will this little program crash when you enter the
enter key?
while True:

if a.isdigit():
print 'isdigit'
elif a[0] == '-' and a[1:].isdigit():
print '- + isdigit'
elif a == 'q':
break
