Day 173 : Convert Decimal to Fraction in Python

 

from fractions import Fraction

# Convert decimal to fraction

decimal_number = input("Enter a Decimal Number:")

fraction_result = Fraction(decimal_number).limit_denominator()

print(f"Decimal: {decimal_number}")

print(f"Fraction: {fraction_result}")

Explanation : 

Let's break down the code step by step:

from fractions import Fraction

This line imports the Fraction class from the fractions module. The Fraction class is used to represent and perform operations with rational numbers.

# Convert decimal to fraction

decimal_number = input("Enter a Decimal Number:")

This line prompts the user to enter a decimal number by using the input function. The entered value is stored in the variable decimal_number.

fraction_result = Fraction(decimal_number).limit_denominator()

Here, the entered decimal_number is converted to a Fraction object using the Fraction class. The limit_denominator() method is then called to limit the denominator of the fraction to a reasonable size.

print(f"Decimal: {decimal_number}")

print(f"Fraction: {fraction_result}")

These lines print the original decimal number entered by the user and the corresponding fraction.

So, when you run this code, it will prompt you to enter a decimal number, convert it to a fraction, and then print both the original decimal and the corresponding fraction. The limit_denominator() method is used to present the fraction in a simplified form with a limited denominator.
