You would have needed something like

Oh, most certainly it has - though it may accept more forms of input
than the OP needs/wants:
>>> from fractions import Fraction
>>> Fraction('2/3')
Fraction(2, 3)
>>> Fraction('2.3')
Fraction(23, 10)
>>> Fraction('2e-3')
Fraction(1, 500)

Since fractions is pure Python it may also be instructive to study its
