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

Try this:

def convert( someList ):
    for item in someList:
        try:
            yield int(item)
        except ValueError:
            yield item

newList= list( convert( oldList ) )
