This is one of the gotchas of if/elif chains and I discuss it in my branching topic in the tutorial. Basically you have to sequence the tests to that you gradually filter out the ones you want. > def getcredits(num): > if num < 7: > return 'Freshman' > elif num >= 7: > return 'Sophomore' return exits the construct so you will always exit here or on the line above, you need to move this test to the bottom. I'd suggest a sequence like: > if num < 7: > elif num <16: > elif num < 26: > elif num >= 16: > elif num >= 7: > else: > return 'Senior' But mixing test types makes it really hard to do reliably. Its better to combine tests like this: if num < 7: retiurn 'Freshman' elif 7 <= num < 16: return 'Sophomore' elif 16 <= num < 26: return 'Junior' else: return 'Senior' Which I think is what you are tring to do? If thats too confusing you can use an explicit and test: if num < 7: ... elif (num >= 7) and (num <16): ... etc... The above is simply a shorthand way of writing the combined tests.
