Converting an improper fraction to a mixed number with python

Question

I need to us python to convert an improper fraction to a mixed number or even a float to a mixed number. My code is as follows:

from fractions import Fraction
nu         


        

Answer 1

from fractions import Fraction
def convert_to_mixed_numeral(num):
    """Format a number as a mixed fraction.

    Examples:
        convert_to_mixed_numeral('-55/10') # '-5 1/2'
        convert_to_mixed_numeral(-55/10) # '-5 1/2'
        convert_to_mixed_numeral(-5.5) # '-5 1/2'

    Args:
        num (int|float|str): The number to format. It is coerced into a string.

    Returns:
        str: ``num`` formatted as a mixed fraction.

    """
    num = Fraction(str(num)) # use str(num) to prevent floating point inaccuracies
    n, d = (num.numerator, num.denominator)
    m, p = divmod(abs(n), d)
    if n < 0:
        m = -m
    return '{} {}/{}'.format(m, p, d) if m != 0 and p > 0 \
        else '{}'.format(m) if m != 0 \
        else '{}/{}'.format(n, d)

The function can be used by passing it the numerator and denominator as a number, string, or Fraction instance. Or it could be modified to take in the numerator and denominator as separate variables.
