Program to perform mathematical operations on two numbers.

In this python basic program, we will perform mathematical operations on two numbers defined by the user.

Steps to solve the program

Take two numbers and a mathematical operation of your choice (+,-,*,/) as input.
Using if-else statements perform the corresponding operations on numbers.
Print the output.

				
					num1 = float(input("Enter number 1: "))
num2 = float(input("Enter number 2: "))
operation = input("Enter operation of your choice: ")

if operation == "+":
    print(num1+num2)
elif operation == "-":
    print(num1-num2)
elif operation == "/":
    print(num1/num2)
elif operation == "*":
    print(num1*num2)
else:
    print("Invalid operation")

Output :

				
					Enter number 1: 25
Enter number 2: 5
Enter operation of your choice: /
5.0

Where pi is equal to 3.14 and r is the radius of the sphere.
Print the output.

				
					r = float(input("Enter radius of the Sphere: "))
volume = 4/3*(3.14*r**2)

print("Volume of Sphere: ",volume)

Output :

				
					Enter radius of the Sphere: 5

find the square root of a number.

perform mathematical operations on two numbers.

Program to find the square root of a number.

In this python basic program, we will find the square root of a number defined by the user.

Steps to solve the program

Import math library.
Take a number as input.
Find the square root of the number using math.sqrt().
Print the output.

				
					import math 
num1 = 9

print(math.sqrt(num1))

Output :

3.0

Program to find LCM

calculate the volume of a sphere.

Python program to find the LCM of two numbers.

In this python basic program, we will find the LCM two numbers defined by the user.

Steps to solve the program

Take two numbers as input through the user.
Using an if-else statement check which number is greater.
Use While loop.
Inside the While loop check whether both numbers divide the greater number or not.
If yes then break the loop otherwise, add 1 to the greater number and let the loop continue.
At the end print the output.

				
					num1 = int(input("Enter number 1: "))
num2 = int(input("Enter number 2: "))

if num1 > num2:
       greater = num1
else:
    greater = num2

while(True):
    if((greater % num1 == 0) and (greater % num2 == 0)):
        lcm = greater
        break
    greater += 1
    
print(f"L.C.M of {num1} and {num2}: {lcm}")

Output :

				
					Enter number 1: 150
Enter number 2: 200
L.C.M of 150 and 200: 600

Program to find HCF

find the square root of a number.

Python program to find HCF of two numbers.

In this python basic program, we will find the HCF of two numbers defined by users.

Steps to solve the program

Take two numbers as input through the user.
Using an if-else statement check which number is smaller.
Use for loop with the range function to iterate over numbers from 1 to the smaller number.
During iteration check whether the iterated number divides both input numbers, if yes then assign that number to the variable.
After the loop is finished print the output.

				
					num1 = int(input("Enter number 1: "))
num2 = int(input("Enter number 2: "))

if num1 > num2:
    smaller = num2
else:
    smaller = num1

for i in range(1, smaller+1):
    if((num1 % i == 0) and (num2 % i == 0)):
        hcf = i 

print(f"H.C.F of {num1} and {num2}: {hcf}")

Output :

				
					Enter number 1: 150
Enter number 2: 200
H.C.F of 150 and 200: 50

find the sum of natural numbers.

Program to find LCM

Python program to find the sum of natural numbers.

In this python basic program, we will find the sum of natural numbers defined by the user.

Steps to solve the program

Take the last number up to which you want to find the sum as input through the user.
Create a variable to store the sum and assign its value equal to 0.
Use for loop with the range function to iterate over natural numbers defined by the user.
During iteration add the respective natural number to the variable that we have created to find the sum.
Print the output.

				
					num = int(input("Enter a number up to which you want to find sum: "))
total = 0

for i in range(1,num+1):
    total += i
    
print("Total: ",total)

Output :

				
					Enter a number up to which you want to find sum: 10
Total:  55

Steps to solve the program

Take a decimal number as input.
Convert the decimal number to its binary number using {0:b}.format(int(num)).
Print the output.

				
					num = int(input("Enter a number: "))

print(f"Binary form of {num} is: ","{0:b}".format(int(num)))

Output :

				
					Enter a number: 25
Binary form of 25 is:  11001

Print the output.

				
					import string
import random
 
n = int(input("Enter length of the string: "))
 
result = ''.join(random.choices(string.ascii_letters, k=n))
 
# print result
print("The generated random string : ",str(result))

Output :

				
					Enter length of the string: 8
The generated random string :  HWyGuDWg
