How to create a simple prime number generator in Python?

Sometimes, we want to create a simple prime number generator in Python.

In this article, we’ll look at how to create a simple prime number generator in Python.

How to create a simple prime number generator in Python?

To create a simple prime number generator in Python, we can create a loop that checks each number being looped through is a prime.

For instance, we write

import math

def main():
    count = 3
    
    while True:
        isprime = True
        
        for x in range(2, int(math.sqrt(count) + 1)):
            if count % x == 0: 
                isprime = False
                break
        
        if isprime:
            print(count)
        
        count += 1

to create the main function that has a while loop that loops from 2 to the square root of count plus 1 rounded to the nearest integer.

Then we divide count by x and get remainder 0, we know count isn’t a prime.

And we set isprime to False and break the while loop.

Then we print the count if count is a prime.

At the end of the loop iteration, we increment count by 1.

Conclusion

To create a simple prime number generator in Python, we can create a loop that checks each number being looped through is a prime.
