Don't understand this.....new to programming and it getting me pissed off

Question

>>> 20 // 6
3
>>> 1.25 % 0.5
0.25

Answer 1

20 // 6 is dividing 20 with 6. however this is integer division so it only sees how many times the integer 6 fits within 20, which is 3.

1.25 % 0.5 returns the remainder when dividing the two numbers. 1.25 / 0.5 = 2 + 0.25, so the answer is 0.25.
