May I suggest that you give it a try for a month, perhaps re-writing a 
small program you already have in a pythonic style (don't simply write c 
in python) & see if your opinion changes.

if not then other suggestions that python is not a language of choice for 
you may be appropriate.

be warned you may find it creates (or increases ) an extreme dislike for 
C & other languages that require braces & semicolons, it did for me 
(especially the semi-colon!)

If in any problem you find yourself doing an immense amount of work, the
answer can be obtained by simple inspection.
