+This feeds a regex to re.sub literally "If it doesn't match letters or spaces, convert it to nothing, process this variable."
+Scrub extranous info or typos.
+r marks it as a string literal (no escaping needed)
+[] indicates a set of characters, special characters become normal.
+^ = start of the string. In a set like this, it matches anything that is not in the string.
+a-z matches lowercase letters.
+Z-Z matches caps letters
+ matches a space
++? essential means "try to match this till you can't"
