Python program to find simple interest

Python program to find simple interest

Concept to learn: Python Basics

# Python program to find simple interest for the given principal amount, rate of interest and time in number of years.

# Inputs for P, R, N

P = 1000

R = 12

N = 1

# Calculating simple interest(SI)

SI = (P * R * N) / 100

# Print SI for the given values

print("Simple interest = ", SI)

Output of Program

Simple interest = 120.0

Python program to print Sum of even numbers between 1 to 100

Python program to print sum of even numbers between 1 to 100 (2 + 4 + 6 + .... + 100). 

Concept to learn: Python while loop

# Python program to print sum of even numbers between 1 to 100 (2+4+6...+100) using while loop.

sum = 0
num = 0

while(num <= 100):
    sum = sum + num
    num = num + 2
print("Sum of even numbers between 1 to 100 is ", sum)

Output of Program

Sum of even numbers between 1 to 100 is 2550

Python program to print sum of odd numbers between 1 to 100 (1 + 3 + 5 + .... + 99). 

Concept to learn: Python while loop

# Python program to print sum of odd numbers between 1 to 100 (1+3+5...+99) using while loop.

sum = 0
num = 1

while(num <= 100):
    sum = sum + num
    num = num + 2
print("Sum of odd numbers between 1 to 100 is ", sum)

Output of Program

Sum of odd numbers between 1 to 100 is 2500

Python program to print sum of 1 to 100

Python program to print sum of 1 to 100. (Concept to learn: Python while loop)

# Python program to print sum of 1 to 100 (1+2+3+...+100) using while loop.

Program code:

sum = 0

num = 1

while(num <= 100):

    sum = sum + num

    num = num + 1

print("The sum is", sum)

Output of program:

The sum is 5050
