Really good video. I've learned a few things. 'match' with a tuple was completely unknown to me before this video. I've seen '_' used, but now understand it. Can someone tell me when the '_' became a feature? If I use it in Python 3.8 will it cause a problem?

Wow, finally a language where a switch construction does not require "break" after each case!

Great video! Btw, at 33:33, technically `case case` doesn't work as you'd expect - the way case statements work, a single variable name after the keyword is actually assigning a variable to the value of the match statement (in this case, the `match` variable). So here you'd have a shadowed `case` variable inside your case block with whatever value was in the `match` variable.

should have mentioned using only 'throw' in an 'except' block to rethrow and maybe how to use underscore for "private" methods. Apart from that great video 👍

At 33:33 you can't do that. Doing "case case:" will match any number (not just 10) and put it in the variable case. I think that's why your editor is underlining it.

@Indently

Ай бұрын

Well spotted, and noted! I clearly didn't do enough research on that because it was a "case" I thought I'd never even dare to attempt. I appreciate you pointing it out :)

Some useful details: ( Better to write this down before I forget something ) "and"/"or" : because of the short circuit system, these can return any object (non booleans). "None": while these represent the absence of a value (like null in other languages), it doesn't mean that every non declared name equals None. It's more of a special value that any object can take. (btw if we use types, by default it's incorrect to assign None). Also we must be careful when writing "assert x" or "if x:" when we want to check for None , because if x is equal to False, it will act as if it is None. This depends on the __bool__ method of the object in question. Asserts: I've read that they only work if __debug__ is True, so I'm instead using "if x: raise Exception". "del": a non recommended keyword. Its behavior depends on the object involved. If it's a list item, del will remove it from lists. "pass": avoid filling placeholders with pass, since you won't be able to differentiate what is supposed to do nothing (for example, an abstract method) and what has its implementation pending. I prefer to "raise NotImplementedError()"

@marckiezeender

Ай бұрын

Just to add about 'pass': I use pass to denote "this block of code does nothing", I use raise NotImplementedError to denote "this block is missing its implementation", and I use ... to denote "this block of code is abstract" (i.e. for a stub file, Protocol method, or abstract method; note that you can't create instances of abstract classes.)

I actually saw the nonlocal in a script at work, it functioned how I thought, but seeing it then just made me wonder why it's even there. It looked like they were just trying to add more lines of code.

very classy Class explanation, lol, fast forward ahead, when you read the text from the file, can you go to a specific line and input data,

Now this is a separate video on coroutines. yield is not just a 'return' statement. It is also an assignment statement. If in a generator called 'foo', you have: new_value = yield old_value a user, baz, of that generator that has declared: def baz.. bar = foo() can then do: current_result = bar.send(my_value) which gets bars's old_value and stores it locally in baz's current_result while at the same time storing baz's my_value in bar's new_value. bar then waits there until anyone calls next(bar). at which point foo's code restarts execution. confused? good, so am I. But I have used these to write a text "continued line" unwrapper, and a clever spacecraft data packet reader in which the length of the packet is not known until the end of sensor scan--with NO, ZERO, NADA if-then clauses. Cyclic Complexity = 1, but it handles all cases WITHOUT indexing past/present data streams, even though the data reading depends on the values of the data stream at different timestamps (read: indices).

Is it possible to overwrite these keywords, like translate them for instance (even if it is bad practice)?

@Indently

With soft keywords you can assign new values to them, but with the built-in ones you would have to change the implementation of Python itself from what I understand. I once created a script that translated my own keywords into Python code, but it was silly and just for fun.

@owtechS

25 күн бұрын

This variable declaration db: str | None = "myd.db" is using type hints, which are annotations used in Python to indicate the expected types of variables. Let me break it down for you: db: This is the name of the variable. :: This indicates that what follows is the type annotation for the variable. str | None: This part indicates that the variable db can hold either a string (str) or None. = "myd.db": This part initializes the variable db with the value "myd.db". Here, "myd.db" is a string, which satisfies the first part of the type hint (str).

Can we please just agree that it’s insane for true and false to be capitalized???

Apparently Python 3.9 doesn't have a soft keyword list, so I think I need to update. What's really weird is that my keyword list has __peg_parser__ in it and I have no clue what that does.

The amount of annotations ( ":" and "->" ) you use are distracting and confusing for me.
