I don't understand the '//' simbol

Question

for example
5 // 2 = ??
300 // 10 = ??

Answer 1

it will take the integer part of the division
7/2 will be 3.5
but
7//2 will give us only the integer 3

Answer 2

In Python this sign // is called the floor division and this % is the modulo operator

The floor division // operator will only provide your answer without remainder

The modulo % operator will only give you the remainder as you answer.

Just in the case of this
>>> 20 // 6 meaning how many times do 6 goes in 20. 6 will go in 20 3times remainder 2 but don't forget your answer will only be 3 because of this sign //

And as for this
>>> 1.25 % 0.5 meaning how many times do 0.5 goes in 1.25. answer = 2.5 remainder

Answer 3

for your example
5 // 2 equals to 2 remainder 1 but your answer should be 2 because floor division operator sign will display the times 2 goes in 5 not the remainder therefore:
5 // 2 = 2

300 // 10 = 30
