with many useful tools, such a function already exists in the Python Library.
>>> from fractions import gcd
>>> def rational(n, d):
g = gcd(n, d)
return (n//g, d//g)
<span>The floor division operator, // , expresses integer division, which rounds
down the fractional part of the result of division. Since we know that g
divides both n and d evenly, integer division is exact in this case.
This revised rational implementation ensures that rationals are expressed
