isPrime bug

This function

python-essential-training-2449125/exercise_files/11_02_e/primes.py

Line 2 in 8697180

def isPrime(n, foundPrimes=None):

returns True for the numbers 4, 6 and 8 despite that those are not prime numbers

Yes, in module primes.py, in line 3:
instead of range(2, int(n**0.5)) should be probably: range(2, int(n**0.5)+1)
Not that I knew it, I just checked other codes on internet :)
And also the function should probably check if n > 1.

I think this is actually fixed in the files on GitHub, not the exercise files from the LIL site though.
