Apr 10, 2025 · isprime () function from the SymPy library checks if a number is prime or not. It prints False for 30, True for 13 and True for 2 because 30 is not prime, while 13 and 2 are prime numbers.

Jan 3, 2018 · In this post, we will write a program in Python to check whether the input number is prime or not. A number is said to be prime if it is only divisible by 1 and itself. For example 13 is a prime number because it is only divisible by 1 and 13, on the other hand 12 is not a prime number because it is divisible by 2, 4, 6 and number itself.
