list of prime numbers from 1 to 100 in python

In this tutorial, we learned to check if a number is prime or not using Python. This function will print the value where is present. Here we have used this function to print the value of num. The format() is a function for handling strings that permits you to do variable substitutions and data formatting. Print('1 is neither prime nor composite') Look at the complete program given below to understand the implementation of the approach. Step 9 - else, print '1 is neither prime nor composite' Python Program Step 8 - if,yes pass the number in the function check_prime_no() as parameter Step 6 - Take input of a number from the user Step 5 - else, print that the 'Number is prime' Step 4 - if you find a factor print 'Number is not prime' and break out of the loop Step 3 - To find the factor simply check for divisibility, if it is a factor then it will divide the number completely leaving 0 as the remainder Step 2- Run a loop from 2 to the number to find if the number has more than two factors Step 1 - Define a function check_prime_no() which will check if the number is prime or not

Take a look at the algorithm of this program to understand the logic behind the program. The program should take the following as input and give output accordingly, Before moving further it is necessary that you have some knowledge about conditional statements in Python. We will use for loop and if-else conditional statements for executing this program. We will follow this approach and find if a number has more than two factors or not to decide if it is prime. Numbers that are not prime are called composite numbers and have more than two factors. First, few prime numbers are- 2,3,5,7,11. Our program should take a number given by the user and display if it is prime or not.Ī Prime Number is a natural number that is greater than 1 and has only two factors, 1 and the number itself. In this tutorial, you will learn how to check if a number is prime or not using Python Programing language.
