In this article, we are going to see how to print all prime numbers between a given range. We have shared code in python language.
What is Prime number?
Prime number is a number who is divisible by 1 and that number only. There are no factors other than these 2 two.
Example of Prime number: 11,13,29 . All of these numbers do not have factors other than 1 and given number. Prime number can only be odd number.
How to find whether a number is prime or not?
For a given number, we will check whether a number do not have factor from 2 till square root of the number. We will run a iterative loop and see if there is any number which is factor of that number.
How to check whether a number is prime through programming
import math def checkPrime(number): if(number<1): return False i=2 while(i<math.sqrt(number)): if(number%i==0): return False break i+=1 return True def getPrimeNumberinRange(number1, number2): if(number1>number2): return "Invalid range" primenumberlist=  j=number1 while(j<number2+1): if(checkPrime(j)): primenumberlist.append(j) j+=1 return primenumberlist print(getPrimeNumberinRange(1000,3000))
