why 7%(5//2) is 1?

Answer 1

// is operator for floor division
% is operator for modulo

for example: 10 // 3 = 3 and 10 % 3 = 1
because: 10 = 3*3 + 1

5 // 2 = 2
7 % 2 = 1

Answer 4

@albert (your nick was not the best choice ;-) )
7 % 2 is modulo-division. This means that the output of this operation is the remainder - here 1.

some more examples:
5 % 3 = 2
14 % 5 = 4
7 % 4 = 3
