Prime numbers in python program. In the Python programming language, prime or not prime. To become a python programming expert, learn basic Python program. To determine whether a number is prime or not, use the for loop in Python. A ” prime number ” is a counting number that can only be divided by itself and one.

a = 17 if a > 1: for i in range(2,a): if (a % i) == 0: print(a,"is not prime number") break else: print(a,"is a prime number")

Output

17 is a prime number

## Prime Number Definition

A prime number is a natural number larger than one that cannot be multiplied by two lesser natural numbers. A composite number is a natural number greater than one that is not prime. In mathematics, a prime number is defined as a number bigger than one with exactly two factors, one and itself. Here are some prime number examples: 2, 3, 31, 101, 149, and so on.

## If Else Statement in Python

If not, then A Python statement determines whether or not an expression is true or false. The “if” statement is executed if a condition is met. Otherwise, the “otherwise” phrase takes effect. This is when conditional statements come into play. Conditional statements allow you to more efficiently manage the flow of your program.

You can create a chain of if statements using the if/else if statement. The if statements are evaluated one after the other until one of the if expressions is true or the end of the if/else if chain is reached. No code blocks are run if the end of the if/else if chain is reached without a true expression.
