Add a parity bit

Python Intermediate alien ages 11-13

The problem

Computers can spot mistakes by adding one extra digit. Write a function add_parity_bit(bits). The text bits is made of 0s and 1s. Add one more digit at the end (0 or 1) so that the whole text has an EVEN number of 1s. Example: "101" becomes "1010", and "111" becomes "1111".

You will practice: error detection, counting, remainder (%), joining text
