[Tutor] file I/O

[Massey, Craig]

Well there you go, thanks. I did a workaround which got there, but I was
looking for something neater like this. I'd love to know how people find out
about these things as I spent a lot of time looking for it. The help with
Activestate is either babyish(Tutorial) or very specific (Language
Reference) and I have trouble finding out how to do things.

Ignore me, I'm a newbie struggling up the learning curve on another language
and not liking it any better this time either. Once I stop feeling stupid
because I don't know how to do stuff like this I'll be happier.

there's strip() method:

>>> s = 'aljsk\n'
>>> s
'aljsk\n'
>>> print s
aljsk

>>> s.strip()
'aljsk'

>>> help(s.strip)
Help on built-in function strip:

strip(...)
    S.strip() -> string
        
        Return a copy of the string S with leading and trailing
        whitespace removed.
