Python Program to Add Two Numbers

num1 = 1.5

num2 = 6.3

sum = float(num1) + float(num2)

print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

Output

The sum of 1.5 and 6.3 is 7.8

num1 = input('Enter first number: ')
num2 = input('Enter second number: ')
sum = float(num1) + float(num2)

print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

Output

Enter first number: 1.5
Enter second number: 6.3
The sum of 1.5 and 6.3 is 7.8

Python Program to Check Prime Number

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

if num > 1:
  
   for i in range(2,num):
       if (num % i) == 0:
           print(num,"is not a prime number")
           print(i,"times",num//i,"is",num)
           break
  else:
       print(num,"is a prime number")
       
else:
   print(num,"is not a prime number")
