How does work in Python

Question

What does the % in a calculation? I can't seem to work out what it does.

Does it work out a percent of the calculation for example: 3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6 is apparently equal to 7. How?

Answer 1

The % (modulo) operator yields the remainder from the division of the first argument by the second. The numeric arguments are first converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the absolute value of the result is strictly smaller than the absolute value of the second operand [2].
