• lambda x, y: x*y, [[1,2],[3,4],[5,6]]
• (1*2)*(3*4)*(5*6)

Solution

from fractions import Fraction from functools import reduce def product(fracs): t = reduce(lambda x, y: x*y, fracs) return t.numerator, t.denominator if __name__ == '__main__': fracs = [] for _ in range(int(input())): fracs.append(Fraction(*map(int, input().split()))) result = product(fracs) print(*result)
