Extract Largest Number from list of strings in python

Question

so I am trying to extract the largest number from a list of strings in python. The string I'm trying to work with looks like this

a = ['a', '3', '5', 'c10', 'foo', 'bar', '999']

And I'm trying to get back the largest number. So in this case, it would be 999 and I wan't it back as an int.

I can't seem to find a pretty way of doing this, hope you guys can help.

a = ['a', '3', '5', 'c1000', 'foo', 'bar', '999']; mx = max( [int(x) for x in a if x.isnumeric()]) # mx is 999 instead of 1000 — Brett Young, Jan 01 '23 at 12:30

 max( [int(x) for x in a if x.isnumeric()])

This only works if the numbers are always positive integers, which is likely, but OP needs to confirm. – Alex Hall Jun 27 '19 at 08:42
Youre right, I still assumed it to be sufficient for OPs needs. Otherwise it would of course be more complicated. – LukasNeugebauer Jun 27 '19 at 08:45
This is sufficient for my case. Thank you – Shadesfear Jun 27 '19 at 08:48
