[Tutor] Find out if a number is even or not

[Riumu Kuraku]

>From "Python docs"

The % (modulo) operator yields the remainder from the division of the
first argument by the second. The numeric arguments are first
converted to a common type. A zero right argument raises the
ZeroDivisionError exception. The arguments may be floating point
numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.)
The modulo operator always yields a result with the same sign as its
second operand (or zero); the absolute value of the result is strictly
smaller than the absolute value of the second operand5.1.

if a number divides by 2, and yields no remainder, it's even.

Be cool and write your own function for this...

def OddorEven(x):
a=0
a=x % 2
if a ==0:
    return "Even"
else:
    eturn "Odd"
