So it really isn't "try-else," ... (and finally) being optional.

What happens when you use try and except statements in a function that both have a return statement in them BUT you also have a finally statement?
And what it seems to do is reach the return statement, ignore it, carry out the finally statement and then go back to the return. I don't observe it as being ignored at all: In [10]: def bla(): ...: try: ...: return "bla" ...: except ZeroDivisionError: ...: print("division by zero!") ...: finally: ...: print("finally called") ...: return "not bla" ...: In [11]: bla() finally called Out[11]: 'bla' If it would have ignored it, it would have returned 'not bla'.

September 22, 2020 -
I understand the concept of try: except: block or try: except: else: but I don't seem to understand purpose of the finally: block.Is there a difference between:
try:
*try something*
except:
*catch and handle error
finally:
*continue rest of the script*And:
try:
*try something*
except:
*catch and handle error
*continue rest of the script without 'finally' block*I suppose there must be some difference,but I can't find any

finally will always execute no matter regardless of any exceptions. You don't even have to use except block. It's useful for cleanup. While code outside of try block would be executed when you handle the exception, you don't always want that. Sometimes it's not the best place to do that or you want to re-raise it after partially handling it. Also you shouldn't use bare except, if you don't expect certain type of exception, your code shouldn't catch it.

The statements in the else block are executed if execution falls off the bottom of the try - if there was no exception. Honestly, I've never found a need.
However, Handling Exceptions notes:
The use of the else clause is better than adding additional code to the try clause because it avoids accidentally catching an exception that wasn’t raised by the code being protected by the try ... except statement.
So, if you have a method that could, for example, throw an IOError, and you want to catch exceptions it raises, but there's something else you want to do if the first operation succeeds, and you don't want to catch an IOError from that operation, you might write something like this:
try:
operation_that_can_throw_ioerror()
except IOError:
handle_the_exception_somehow()
else:
# we don't want to catch the IOError if it's raised
another_operation_that_can_throw_ioerror()
finally:
something_we_always_need_to_do()
If you just put another_operation_that_can_throw_ioerror() after operation_that_can_throw_ioerror, the except would catch the second call's errors. And if you put it after the whole try block, it'll always be run, and not until after the finally. The else lets you make sure
- the second operation's only run if there's no exception,
- it's run before the
finallyblock, and - any
IOErrors it raises aren't caught here

There is one big reason to use else - style and readability. It's generally a good idea to keep code that can cause exceptions near the code that deals with them. For example, compare these:
try:
from EasyDialogs import AskPassword
# 20 other lines
getpass = AskPassword
except ImportError:
getpass = default_getpass
and
try:
from EasyDialogs import AskPassword
except ImportError:
getpass = default_getpass
else:
# 20 other lines
getpass = AskPassword
The second one is good when the except can't return early, or re-throw the exception. If possible, I would have written:
try:
from EasyDialogs import AskPassword
except ImportError:
getpass = default_getpass
return False # or throw Exception('something more descriptive')
# 20 other lines
getpass = AskPassword
Note: Answer copied from recently-posted duplicate here, hence all this "AskPassword" stuff.

Answer: It's a default block of code that executes irrespective of exception. It's generally put after the catch block. It only have some default statements to be executed.
