I've created a function in python to check whether a manually inputed number is a prime number or not. The code lines are showed as follow: def checkIfPrime(numberToCheck): for x in range(2,numberToCheck): if (numberToCheck%x==0): return False return True answer=checkIfPrime(int(in...
We divide the number by the prime numbers repeatedly. We can implement this in Python using nested loops. The first loop determines whether a number is a prime number or not. The second loop divides this prime number and the given number. If the remainder is zero, we append the prime ...

So i tried writing a program for testing whether a number is prime or not. But then found my function painfully slow.Here is the function : from math import sqrt def isPrime(x): if x%2==0 or x%3==0: return 0 Python 11 5964 prime number by: lostinpython | last post by:...
