Does textwrap module has what you need?

 >>> import textwrap
 >>> 
textwrap.wrap('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa', 
78)
['aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa', 
'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa']
 >>> textwrap.wrap('This is a very long String. A linewrap module has 
couple functions which might help you to accoplish your goal. HTH', 78)
['This is a very long String. A linewrap module has couple functions 
which might', 'help you to accoplish your goal. HTH']
