 # Addition
sum = number1 + number2
 # To display the sum
print("Addition:" ,sum)
# Subtraction
sub = number1 -number2
# To display the subtraction
print("Subtraction:" ,sub)
# Multiplication
multiply = number1 *number2
# To display the multiplication
print("Multiplication:" ,multiply)
# Division
divide = number1 + number2
# To display the sum
print("Division:" ,divide)
Output

Enter the First number: 4

Enter the Second number: 2

Addition: 6

Subtraction: 2

Multiplication: 8

Division: 2

Python program to find the factorial of a given number

A factorial of a given number calculated by findingthe product of all the numbers from 1 to the user specified number.

Using traditional iterationmethod


# factorial of given number
def factorial(num):
    ifnum< 0:
        return 0
    elifnum == 0 or num == 1:
        return 1
    else:
        fact = 1
        while(num> 1):
            fact= fact * num
            num=num - 1
        return fact
#Getting input from user
num = input("Enter the Given number: ")
print("Factorial:",factorial(num))
Output Enter the Given number: 3

Factorial: 6

Using in-built function


import math
#Getting input from user
num = input("Enter the Given number: ")
#in-built function
fact=math.factorial(num)
print("Factorial of given number:",fact)
Output Enter the Given number: 4

Factorial of given number: 24

Python program to find the simple and compound interest


P = principle amount
T = time period
R = rate of interest
A =amount 
T =time span
Simple interest formula: 
(P x T x R)/100
Compound interest formula: 
A = P(1 + R/100) t 
Compound Interest = A – P 
#Getting input from user
p = input("Enter the Principle amount: ")
t = input("Enter the time period: ")
r = input("Enter the rate of interest: ")
#to calculate simple interest
SI = (p * t * r)/100
print('Simple Interest:', SI)
#to calculate compound interest
Amount = p * (pow((1 + r/ 100), t))
CI = Amount - principle
print("Compound Interest:", CI)
Output Enter the Principle amount: 5000

Enter the time period: 2

Enter the rate of interest: 5

Simple Interest: 500

Compound Interest: 5500

Python program to check whether the given number is prime or composite

The prime number is a whole number with two integral divisors i.e., divisible by 1 and itself. The composite number is a whole number with more than two integral divisors. 

#Getting input from user
num = int(input("Enter a number : "))
#to check prime or composite
ifnum == 0 or 1:
print(num, "is a neither prime NOR composite number")
elifnum> 1:
fori in range(2, num):
if (num % i) == 0:
print(num, "is NOT a prime number")
break
else:
print(num, "is a PRIME number")
else:
print(num, "is a COMPOSITE number")
Output Enter a number: 3

3 is a PRIME number

Python program to find the biggest of three numbers


# Getting input from user
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
num3 = int(input("Enter third number: "))
#to find the biggest number
if (num1 >= num2) and (num1 >= num3):
big = num1
elif (num2 >= num1) and (num2 >= num3):
big = num2
else:
big = num3
print("The largest of three numbers is",big)
Output Enter first number: 12

Enter second number: 17

Enter third number: 25

The largest number is 25

Python Program to Display the multiplication Table

To displays the multiplication table of variable num (from 1 to 10). 

# To take input from the user
number = int(input("Enter the number for multiplication table : "))
# Iterate 10 times from i = 1 to 10
fori in range(1, 11):
print(number, 'x', i, '=', number*i)
Output Enter the number for multiplication table: 2

2 x 1 = 2

2 x 2 = 24

2 x 3 = 36

2 x 4 = 48

2 x 5 = 60

2 x 6 = 72

2 x 7 = 84

2 x 8 = 96

2 x 9 = 108

2 x 10 = 120

Python Program to Check Armstrong Number

Armstrong number is a number equal to the sum of the cubes of its own digits. For example, 370 is an Armstrong number since 153 = 1*1*1 + 5*5*5 + 3*3*3. 

# Getinput from the user
num = int(input("Enter a number: "))
sum = 0
# Tofind the sum of the cube of each digit
tem = num
while tem> 0:
digit = tem % 10
sum += digit ** 3
tem //= 10
ifnum == sum:
print(num,"is an Armstrong number")
else:
print(num,"is not an Armstrong number")
Output

Enter a number: 370

370 is an Armstrong number

Python Program to Check Whether a Given String is Palindrome or Not

________________________________________A palindrome is a string that is the same when read forward and backward as well. For example: mom, madam,pop,radar 

# Getting input from user
string=input(("Enter a string:"))
if(string==string[::-1]):
      print("The string is a palindrome")
else:
      print("Not a palindrome")
Output

The string is a palindrome.
