python - Manipulate a part of variable while keeping the original intact -

-



what cleanest way manipulate / use / remove part of variable whilst keeping original variable intact.

lets wanted value in following list corresponds highest numerical value

so example:

max([1, 2, '3a', '10b'])

should evaluated as

max([1, 2, 3, 10])

and value '10b' should returned

extended approach using re.search() function:

import re  max_item = max([1, 2, '3abc', '10bc'], key=lambda n: int(re.search(r'\d+', str(n)).group(0))) print(max_item)

the output:

10bc
