Was challenging(fun) to code and strung together concepts of randomization, lists, logic(no repeats) and functions. Using dictionaries could of made this easier, had I known how to string together 3 values instead of the regular 2.
Improvements: -Calculating score -Making it so that users do not have to type in quotations for everything.
Use raw_input() instead.
A variant for delete(L,n):
but you could avoid it completely by using
(and replacing otherTwo by secList afterwards).
Also, instead of globally catching the IndexError, replace the infinite loop with:
