Given a time, your mission is to calculate the angle between the hour hand and the minute hand on an analog clock and return it in radians in lowest terms.

clockRadian.py

import fractions as f
def clockRadian(time):
    h, m = tuple(map(int, time.split(':')))
    t = abs((h % 12) * 60 - m * 12 + m)
    t = 720 - t if t > 360 else t
    if t == 0:
        return "0"
    a = f.Fraction(t, 360)
    b = a.numerator
    c = a.denominator
    return "{}pi/{} ".format(b if b > 1 else '', c)[0:-1 if c > 1 else -3]
