The variables stats.team1.school and stats.team2.school return ParseResults object and not a string. This causes an TypeError exception to be thrown with this message:
TypeError: cannot concatenate 'str' and 'ParseResults' objects
The remedy is to change the effected lines like this:
if stats.team1.score > stats.team2.score:
result = "won by " + str(stats.team1.school)
else:
result = "won by " + str(stats.team2.school)
adding the str() method to pull out the school's name in a string.
It is not clear to me why the '+' concatenation operator needs this help while further down in the code the 'print' format operation does not.
