stuck in the python program

[harleen kaur]

from math import *

def main():
n = abs(input("Enter a number: "))
i = 2
msg = 'is a prime number.'
while i <= sqrt(n):
if n % i == 0:
msg = 'is not a prime number.'
i = i + 1
print n, msg


main()



how to correct this program, when i run it it said, sqrt is not defined or
if i do
from math import sqrt
even though it is not working
