This does what you are trying to do, but with all the extraneous code eliminated.
Notice that strings are iterables, just like lists. Any time you are making a list
of single characters, you should probably use a string. Also notice that we write
`'xxx'.upper()`, not `str.upper('xxx')`. Also note that it is silly to write `
if result='N': pass`. Just test for what you want to know.
