20//6=3

Question

I can't understand it plzz help

Answer 1

// is floor division in python. It finds the quotient when 2 numbers are divided. The catch is it must me a whole number and can have a remainder
In this case 20 // 6 has quotient 3 and remainder 2.
In other words floor division floors (rounds off to the nearest interest lesser or equal to it) the quotient.

In real division, 20 ÷ 6 = 3.333333...... but in floor division 3.3333... gets floored and becomes 3 and remainder is then 2. (as 3 × 6 +2 = 20)

Extra info: The opposite of flooring is ceiling. Ceiling rounds the number to the nearest integer greater or equal to it.
