What is Python's equivalent of Java's standard for-loop?
I'm writing a simple algorithm to check the primality of an integer and I'm having a problem translating this Java code into Python: for (int i = 3; i < Math.sqrt(n); i += 2) { if (n % i == 0) return false; } So, I've been trying to use this, but I'm obviously skipping the division by 3: i = 3 while (i < int(math.sqrt(n))): i += 2 # where do I put this? if (n % i == 0): return False The only for -loop in Python is technically a "for-each", so you can use something like for i in xrange(3, int(math.sqrt(n)), 2): # use 'range' in Python 3 if n % i == 0: return False Of course, Python can do
