Python Conditional Statement Coding Exercise Solution

def is_it_prime(n):
    #TODO: Write your code here.
    for i in range (2, n):
        if n % i == 0:
            return False
        else:
            return True
        

The solution above is ok but however does not evaluate integers less than 3( i.e. 0,1,2). A simple alternative that works for all integers would like as follows:
def is_it_prime(n):
if n<2:
return (False)
elif n==2 or n==3:
return(True)
elif n%2!=0 and n%3!=0:
return (True)
else:
return (False)

def is_it_prime(n):
prime = None

if n == 0:
    prime = False 
elif n == 1:
    prime = True
elif n == 2:
    prime = True
else:
    for i in range(2, n):
        if n % i == 0:
            prime = False
            break
        else:
            prime = True
return prime

print(is_it_prime(3))

def is_prime(n):
for i in range(2, n\2+1):
if n % i == 0:
return False
else:
return True
