Python converting list of strings to list of integers

Question

hi I'm trying to convert this list of strings: lists=['111,222','121,121'] into a list of integers but keep running into errors, any advice would be helpful. I've tried:

results=[int(i) for i in lists]
print(results)

but keep getting "invalid literal for int() with base 10: '111,222'"

Answer 1

You need to remove the commas, for example:

lists=['111,222','121,121']
result = [int(s.replace(',', '')) for s in lists]
print(result)

Output

[111222, 121121]

Answer 2

This should work

import re

lists=['111,222','121,121']
results = [ int("".join(re.findall('[0-9]+', element))) for element in lists ] 

# results = [111222, 121121]
