Answer to Question #332854 in Python for Dhea M. Maddela

Question

Create a Python script that will reduce an input fraction to its lowest term. The program requirements will be:

1. Function that will check first if the input fraction is a VALID fraction.
2. Function that will split a VALID fraction and return a list that consists the numerator and denominator.
3. Function that will accept two parameters (numerator and denominator) to determine the greatest common divisor.
4. Function that will accept two parameters (numerator, denominator) and will return the reduced fraction.

Sample Output:

Input a fraction? : 4/6

Reduced fraction is 2/3

I need the code to have an output stated above and that the requirements are met in the code.

Answer 1

 from math import gcd


def validate(data): #1
    values = data.split('/')
    if len(values) == 2 and all(i.isdigit() for i in values):
        if len(values) > 1 and int(values[1]) == 0:
            print("Invalid fraction")
            return True
        else:
            return False
    else:
        print("It is not fraction")
        return True


def split(data): #2
    values = data.split('/')
    return values


def search_gcd(x, y): #3
    d = gcd(x, y)
    return d


def reduce_fraction(x, y): #4
    d = gcd(x, y)
    x = x // d
    y = y // d
    result = str(x) + "/" + str(y)
    return result


def main():
    you_fraction = "a/b"
    while validate(you_fraction) or you_fraction == 'a/b':
        you_fraction = input("Input a fraction: ")

    you_fraction_split = split(you_fraction)
    a = int(you_fraction_split[0])
    b = int(you_fraction_split[1])
    my_gcd = search_gcd(a, b)
    print("Reduce fraction is " + reduce_fraction(a, b))

    main()
