Stripping

I'm a little bit confused with strip function in module STRING sometime it works sometime not.For example

Code:

>> a = 'myname/is'
>> print string.strip(a,'/')

>> myname/is

so what's wrong?

Code:

>>> import string
>>> help(string.strip)
Help on function strip in module string:

strip(s, chars=None)
    strip(s [,chars]) -> string
    
    Return a copy of the string s with leading and trailing
    whitespace removed.
    If chars is given and not None, remove characters in chars instead.
    If chars is unicode, S will be converted to unicode before stripping.
>>> string.strip('myname/is', '/')
'myname/is'
>>> string.strip('///myname/is///', '/')
'myname/is'
>>>

BTW, the functions in the string module are the old way of doing it. Unless your code needs to be backwards compatible with Python 1.5.2 and earlier, then the preferred way is to use the methods on the string object itself:

Code:

>>> '///myname/is///'.strip('/')
'myname/is'
>>>

If you want to replace all occurances of particular strings/chars then you should look at the replace() method - very handy, i seem to use it when ever i do any string manipulation.

Have fun,

Mark.
