% Operator

Question

evens=[i**2 for i in range(10) if i**2 % 2 == 0]

print(evens)

What is the % 2 == 0 saying in the above list comprehension. Please give me an actual numeric example.

Answer 1

% (Modulus) almost same with / (division).
The difference is when 10 / 2 = 5 but when 10 % 2 = 0 Because it doesnt remains anything...

i'll just give some example...

100 % 5 = 0 ✔
because it doesnt remains anything...

20 % 4 = 2 ✔
because its only remain 2...

7 % 4 = 3 ✔
because its only remain 3...

Answer 2

It means only even numbers are accepted.

All even numbers are divided by 2.
If we divide a number by 2 and there is no remainder ,then it expressed by

number % 2 = 0.

Modulus sign ( % ) used to determine remainder.

4%2 = 0
16%2 = 0
5%2 =1 [ remainder 1]
