I chose a code snippet from a previous class of mine that was written in Python. The code is a function that is used to determine if a given number is a prime number and returns a boolean on its primality.
The areas requiring improvement are the redundant comparisons for n == 2, and n % 2 == 0.
The goals are to refactor the code by eliminating the redundant comparisons and modifying the code to keep functionality after refactoring.
def is_prime(n):
if n <= 1:
return False
elif n == 2:
return True
elif n % 2 == 0:
return False
else:
for i in range(3, int(n**0.5) + 1, 2):
if n % i == 0:
return False
return True```
