Extracting only characters from a string in Python

Question

In Python, I want to extract only the characters from a string.

Consider I have the following string,

input = \"{(\'players\',): 24, (\'year\',): 28         


        

Answer 1

What about doing this?

>>> import ast
>>> " ".join([k[0] for k in ast.literal_eval("{('players',): 24, ('year',): 28, ('money',): 19, ('ipod',): 36, ('case',): 23, ('mini',): 46}").keys()])
'case mini year money ipod players'
