In a if/else statement. I try to do a code for defining if the number is even or odd

Question

I have seen the if x%2==1 and x&2 but I don't understand how that works I don't understand the x%2==1 and x&2 means in the if statement

x=int(input("Write your number to define if either is even or odd"))
if x%2==1:
   print('odd')
else:
   print('even')

This work well but I don't understand how they define numbers

`a % b` means `a mod b` (which is math, look up what a modulo is), and `a & b` means `a BYTEWISE AND b` (which is coding, about the same as `and`, but with numbers instead of booleans) — Eb946207, Jan 16 '19 at 03:55

% represents modulus which, when applied to integers, measures the remainder of dividing the numerator by the denominator.

In Python, X % 2 == 0 is used to check whether X / 2 has a remainder or not.

Another way to think of it is, X % 2 == 0 checks whether or not 2 is a factor of X.

if X % 2 == 0:
    # 2 is a factor of X, therefore X is even
    is_even = True
else:
    # 2 is not a factor of X, therefore X is odd
    is_even = False
