I love how his haircut evolves through the episodes, as well as my knowledge after watching them! Keep it up, very enlightening :)

I am so grateful to all the Anthony explains videos that I get to see all of them early in my career. Would have taken me some time to learn a lot of the concepts on my own.

Personally I prefer: try-except-else-finally
over: try-except-finally-else
Having the finally at the end makes imho more sense. Since it runs after else.

When talking about exceptions, I would also mention, what return statement in the various blocks does.
For me it was confusing at the beginning, so maybe it would help others.
For example:
try:
foo()
return a
except:
...
else:
return b
finally:
return c

Nice compeehensive guide to exceptions. Thanks. It is good reminder for all of that thing.

That was great. I felt pretty confident in my exception handling, but that was very informative.

good one! prob worth noting not all try-except languages (e.g. JS) have the else case.

can you also demonstrate
1) Nested Try /Except
2) A try except inside a while-loop, for example, i have 10 id need to update or do whoever from the db, and any one of the action is fail, do you show a guide on this?
thanks
