Question

I have a string in the form of:

s = 'A - 13, B - 14, C - 29, M - 99'

and so on (the length varies). What is the easiest way to create a dictionary from this?

A: 13, B: 14, C: 29 ...

I know I can split but I can’t get the right syntax on how to do it. If I split on -, then how do I join the two parts?

Iterating over this seems to much of a pain.

Answer 1

>>> s = 'A - 13, B - 14, C - 29, M - 99'
>>> dict(e.split(' - ') for e in s.split(','))
{'A': '13', 'C': '29', 'B': '14', 'M': '99'}

EDIT: The next solution is for when you want the values as integers, which I think is what you want.

>>> dict((k, int(v)) for k, v in (e.split(' - ') for e in s.split(',')))
{'A': 13, ' B': 14, ' M': 99, ' C': 29}
