Python program to perform basic arithmetic operations

Basic Arithmetic operations

• Addition
• Subtraction
• Multiplication
• Division

Program

#Getting input from user number1 = input(Enter the First number: ) number2 = input(Enter the Second number: ) # 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.

# Get input from the user num = int(input(Enter a number: )) sum = 0 # To find 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.
