[Python] Try/except

[matiboy]

Explain why your try/finally statement in database.py does not serve the purpose of catching exceptions and edit the code to handle expected exceptions.

Explain why it is bad practice to use except: without specifying the catchable exceptions

[ai550]

The reason I didn't catch exceptions in my try/finally statement is that I get everything right from 1st try and have an optimistic view on life.
Ok, jokes aside. I seriously can't recall how I missed that part. I guess I should just fix that.

Using except without specifying its type may generally cause ambiguity during debugging, where developer's expectations of one error are substituted with another.
