How to separate rubles from kopecks?

Question

Python

Answer 1

price = input()
r, c = (list(map(int, price.split('.'))) + [0])[:2]

and regexps are really useless here. At least not for such simple cases.

Answer 2

import re
price = input('Цена: ')
a = re.findall(r"\d+\.", price)[0]
b = re.sub(f"{a}", '', price)
a = re.sub(r'\.', '', a)
print(f"{a}\n{b}")

Answer 3

What's the problem?
You have done everything right. Though not optimal.
Multiply pennies by 100.
