As a learner, you may get to solve a lot of questions related to percentages in Python Programming in your School or College.
What is Percentage?
A percentage is a way of expressing a fraction as a portion of 100.
Examples: 1/2 can be expressed as a percentage by multiplying it by 100 = 50%
 4/5 can be expressed as a percentage by multiplying it by 100 = 80%
 2/3 can be expressed as a percentage by multiplying it by 100 = 66.67%
 7/10 can be expressed as a percentage by multiplying it by 100 = 70%
 3/8 can be expressed as a percentage by multiplying it by 100 = 37.5%
Percentages are used in finance, statistics, and other fields to compare numbers relative to a whole.
In Python, you can calculate a percentage by multiplying a number by 100 and dividing it by another number
Program 1: If a student scored 80 out of 100 on a test, what is their percentage score?
# Marks Optained
score = 80
# Of Total Marks
total = 100
# Percentage Calculation
percentage = (score / total) * 100
# Printing the result
print(f"The Percentage scored is {percentage:.2f}%")
Output:
The Percentage scored is 80.00%
Program 2: Calculate Percentage based on user input of marks scored of total marks?
'''
Example 2:
Calculate the Percentage of Python Program
using User input
Author: Code2are.org
Date: 21022023
'''
# Marks Obtained
score = int(input("Enter Marks Scored: "))
# Of total Marks
total = int(input("Enter Total Marks: "))
# Percentage Calculation
percentage = (score / total) * 100
# Printing the result
print(f"The Percentage scored is {percentage:.2f}%")
Output:
Enter Marks Scored: 45
Enter Total Marks: 200
The Percentage scored is 22.50%
