Letters In Any Case

A letter menu: A) Add one adds one to a counter and prints Count: <n>, Q) Quit prints Goodbye! and leaves the loop, anything else prints Unknown choice - try again.. The dispatch is written; fix the line that reads the choice so that spaces around the letter and lower-case letters are accepted too, using .strip() and .upper() on what input() returns. Input: one choice per line, the last one q or Q. The prompt Choice: is part of the output, so each message follows it on the same line.
