Splitting strings

[Eyes Of Madness]

I'm doing a program for a class of mine and I am having trouble splitting my strings up. I know you can do something like:

a = '012345'
a[0:3]
returns 012

but I am inputing strings of varying length and I cant just do the above notation. I need to split the string into groups of 3 in order to work. Any help would be much appreciated.

You can use that notation, you just need to use a loop and probably the range function (docs here in the Python Library Reference). Or you could use the slice function from the same source.

>>> import textwrap
>>> s="123456"
>>> textwrap.wrap(s,3)
['123', '456']

[code=Python]>>> import string
>>> s = string.ascii_le tters+string.di gits
>>> n=3
>>> [s[i:i+n] for i in range(0,len(s), n)]
['abc', 'def', 'ghi', 'jkl', 'mno', 'pqr', 'stu', 'vwx', 'yzA', 'BCD', 'EFG', 'HIJ', 'KLM', 'NOP', 'QRS', 'TUV', 'WXY', 'Z01', '234', '567', '89']
>>> [/code]
