How to print out whole numbers alongside fractions in Python using fraction import

Question

Im trying to print out a whole numbers alongside rational fractions

E.g: 3 1/2 , **not **7/2

I wanted to try to use if statements like if num1 >= den1: whole +=

though i was afraid that wasnt gonna work or mess up everything else i wrote in the code

import fractions

num1 = int(input('Enter 1st number Numerator: '))
den1 = int(input('Enter 1st number Denominator: '))

num2 = int(input('Enter 2nd number Numerator: '))
den2 = int(input('Enter 2nd number Denominator: '))

f1 = fractions.Fraction(num1, den1)
f2 = fractions.Fraction(num2, den2)

equ = str(input('Select Operation, +, * or /?: '))

if equ == '*':
  print('{} * {} = {}'.format(f1, f2, f1 * f2))

if equ == '/':
    print('{} / {} = {}'.format(f1, f2, f1 / f2))

if equ == '+':
    print('{} + {} = {}'.format(f1, f2, f1 + f2))

the output is always

1/4 + 5/4 = 3/2

not

1/4 + 5/4 = 1 1/2

To print the output in the format you desire, you can extract the whole number and the fractional part separately and format the output accordingly. Here's a code you can use to do this:

import fractions

num1 = int(input('Enter 1st number Numerator: '))
den1 = int(input('Enter 1st number Denominator: '))

num2 = int(input('Enter 2nd number Numerator: '))
den2 = int(input('Enter 2nd number Denominator: '))

f1 = fractions.Fraction(num1, den1)
f2 = fractions.Fraction(num2, den2)

equ = str(input('Select Operation, +, * or /?: '))

if equ == '*':
    result = f1 * f2
elif equ == '/':
    result = f1 / f2
elif equ == '+':
    result = f1 + f2

whole = result.numerator // result.denominator
remainder = result.numerator % result.denominator

if whole != 0 and remainder != 0:
    print('{} {}/{} = {} {}/{}'.format(f1, f2, result.numerator, whole, remainder, result.denominator))
elif whole != 0:
    print('{} {}/{} = {}'.format(f1, f2, result.numerator, whole))
else:
    print('{} {}/{} = {}/{}'.format(f1, f2, result.numerator, remainder, result.denominator))

In this code, I've added a section after the computation to extract the whole number and the remainder of the fraction. Then, I check the conditions to format the output correctly. If the whole number and remainder are both non-zero, I print the result in the format of "whole_number remainder/denominator." If only the whole number is non-zero, I print it as "whole_number." Otherwise, I print it as "remainder/denominator."

Now the output should appear as you what you wanted!
