Explanation:-

• Take a no as an input from the user & store the number in variable number then and pass on this number to a prime function.
• Check if the number is greater then 1 if not then show a message representing enter the valid number.
• Iterate over the range from 2 to number check if the number is divisible from any of these numbers if yes then prime as number is not a prime no else prime the entered number is prime.

Code:-

number = int(input("Enter a number: "))  
def prime(number):
 if number > 1:  
   for i in range(2,number):  
       if (number % i) == 0:  
          print(number,"is not a prime number")     
          break  
   else:  
       print(number,"is a prime number") 
 else:
     print("Enter valid number")
prime(number)
