(Python) How to extract numbers from a string (without regex)? [duplicate]

Question

I would like to extract all the numbers contained in a string. I can't use regex, is there any other way?

Example:

minput = "BLP45PP32AMPY"

Result:

4532

Answer 1

You can use str.isnumeric:

minput = "BLP45PP32AMPY"

number = int("".join(ch for ch in minput if ch.isnumeric()))
print(number)

Prints:

4532
