check if the number is less than or equal to 1; if so, it’s not prime. Then, iterate from 2 to the square root of the number, checking for divisibility. If the number is divisible by any of these, it’s not prime; otherwise, it is. Here’s a sample code snippet: ...

How to Check Python Prime Numbers? To check/determine whether the input number is prime, the following code is used in Python. Here, the function called “check_prime()” is declared in the program, which retrieves the Boolean value whether the number is prime or not: ...
