Prime Number in Python

Write a Program in Python to check if a Number is a prime number or not.

# Starting with A default function for finding the Prime number
def PrimeChecker(Number_T4Tutorials):  
    # finding that given number is more than 1  
    if Number_T4Tutorials > 1:  
        # Iterating over the given number with for loop  
        for j in range(2, int(Number_T4Tutorials/2) + 1):  
            # If the given number is divisible or not  
            if (Number_T4Tutorials % j) == 0:  
                print(Number_T4Tutorials, "is not a prime number.")  
                break  
        # otherwise it is a prime number  
        else:  
            print(Number_T4Tutorials, "is a prime number")  
    # If the given number is 1  
    else:  
        print(Number_T4Tutorials, "is not a prime number")  
# source code to Take an input number from the user by keyboard  
Number_T4Tutorials = int(input("Enter an input number:"))  
# Displaying the result  
PrimeChecker(Number_T4Tutorials)

Output

Enter an input number:4
4 is not a prime number.
