Functions and if elif problem

[ndc85430]

Of course it does. On line 9 (and the others really), your condition is wrong. You need to write month == "September" or month == "October" or month == "November".

Non-empty strings evaluate to True, so if month isn't "September", the string "October" is tested and since that evaluates to True (the term used is "truthy") line 10 is executed. See the docs for more info.
