Python Coding challenge - Day 768| What is the output of the following Python Code?

 

Code Explanation:

1) from fractions import Fraction

Imports the Fraction class from Python’s standard fractions module.

Fraction represents rational numbers exactly as numerator/denominator (no binary floating error).

Use it when you need exact rational arithmetic instead of floats.

2) f1 = Fraction(2, 3)

Creates a Fraction object representing 2/3.

Internally stored as numerator 2 and denominator 3.

type(f1) is fractions.Fraction.

3) f2 = Fraction(3, 4)

Creates a second Fraction object representing 3/4.

Internally numerator 3, denominator 4.

4) result = f1 + f2

Adds the two fractions exactly (rational addition).

Calculation shown stepwise:

Convert to common denominator: 2/3 = 8/12, 3/4 = 9/12.

Add: 8/12 + 9/12 = 17/12.

result is a Fraction(17, 12) (17/12). This is already in lowest terms.

5) print(result, float(result))

print(result) displays the Fraction in string form: "17/12".

float(result) converts the rational 17/12 to a floating-point approximation: 1.4166666666666667.

The decimal is approximate because float uses binary floating point.

Final printed output

17/12 1.4166666666666667
