How to convert strings numbers to integers in a list?

Question

I have a list say:

[\'batting average\', \'306\', \'ERA\', \'1710\']

How can I convert the intended numbers without touching the strings?

Answer 1

a= ['batting average', '306', 'ERA', '1710.5']

[f if sum([c.isalpha() for c in f]) else float(f) for f in a ]

if your list contains float, string and int (as pointed about by @d.putto in the comment)
