maiden skiff
I hope you have a good night
vocal basin
yes, [] for generics now
with inferred variance

already discussed here some time ago
maiden skiff
How's work?
it's better than yesterday
vocal basin
shorthand for TypeVars
stuck furnace
It's fairly natural because it matches how you use the type.
rugged root
stuck furnace
So like instead of doing ```py
class Foo(Generic[T]):
...
x: Foo[int]
you can dopy
class Foo[T]:
...
x: Foo[int]
variadic types often require 2-3 TypeVars with different variance
if they, for example, have factory methods
stuck furnace
Yeah it can really slow you down.
vocal basin
typing makes it simpler for me
typeless code takes me more effort to read
stuck furnace
But because it's optional, if you can't figure out the right way to type something, you can always just leave the types off.

def tuple_of_two[T](element: T) -> tuple[T, T]:

no it's not
polymorphism
one of the types of it
why would it be enforced
it does not impact runtime in any way after its parsed unless you pull the annotations out of the functions
@mortal burrow you're thinking of different polymorphism
stuck furnace
As long as you don't do anything to the objects that can't be done to their bounding type, you're good.
vocal basin

def tuple_of_two[T](element: T) -> tuple[T, T]:

this does not need to change behaviour based on the type
if it was something like Rust, it would have to, but not completely
vocal basin
this does not need to change behaviour based on the type
this is true for Java/C#/Python
generics in such languages don't need defining a function for each type
mortal burrow
ahh
stuck furnace
An object's type tells you that it has certain methods and attributes. Any sub-type of that type should also support those same methods and attributes, and they should behave in a compatible way.
vocal basin
whereas in C++/Rust, you do define function per each type
because different types have different sizes

sololearn's courses aren't good
vocal basin
w3schools.com is very easy for learning Python
same for w3schools
both sites seem sub par
lofty crater
I see
vocal basin
sololearn's courses aren't good
specifically for:
-- factual errors
-- incorrect/incomplete definitions/details of some concepts
-- answers lack formatting (one big example is the question where one answers is "None" instead of "None of the above"; and, given that there's no way to tell None and None apart on that site, this is quite confusing)
vocal basin
same for w3schools
w3schools is quite general
they try to offer tutorials for everything
(that doesn't always end up well)
official Python tutorial is more reliable and up-to-date on most of the topics
https://docs.python.org/3/tutorial/index.html
though it lacks interactivity
@lofty crater what do you mean by extended?
adding new options during runtime?
usually that would involve something other than enum
for the following reason
suppose you have two separate pieces of code:
- uses the enum and handles all the possible cases
- adds new value to the enum
this results into first part becoming incorrect
second part breaks the second part
the "contract" of an enum is that it's exactly one of the options provided
how do you use the enum?
if the task you're trying to solve is:
do something based on the type of the value
it's probably better to factor out that behaviour into a method
or something equivalent to a method
you can look into how SQLAlchemy does the table names thing
it doesn't use a separate method but it does use a field/attribute for each type
though, given that it's Python, everything happens during runtime
there are static constructors in languages like C#
not compile-time but works

@midnight agate no, I don't go for the helper role
why is the MyFrame.welcome using root instead of self.root?
currently trying to figure out why self.data isn't showing up in self.winfo_children()
ah, it's a variable not a widget
where does MyFrame's .pack get called?
does MyFrame or any of its children ever get displayed?
it shows
text
button
button
right?
civic zephyr
vocal basin
these aren't children of MyFrame
civic zephyr
vocal basin
these aren't children of `MyFrame`
they are children of root
in welcome
change all root to self
in __init__
add self.pack()
vocal basin
looks like you didn't change to self for the exit button
no
you still have root there
apparently
previous implementation repeatedly called welcome
which created buttons as children of root
therefore those buttons weren't children of self
that's why they weren't cleared
you could've just created the buttons only once
right now self.welcome() gets called repeatedly
it should probably be named something different then
reset given that it does both clear and setup

line 9 in the `...` module is missing `()`

Item is missing __eq__ and __hash__ implementation
seems like subtotal is using k.get_price

now, it treats two items with the same name as equal
in a real, app, I'd expect there to be a separate id field for each Item
if you're guaranteed to create each object no more than once, then the current implementation is fine

self.root -> self

grid should be called on self.dairy_button
partial doesn't have grid
maybe there shouldn't be a self.dairy_button at all
just
Button(
self, text="Dairy", command=partial(self.start, Item.dairy_items)
).grid(row=2, column=5)
you can't do grid inside Button
at least via the .grid method
you'd still have to assign it to something
to a variable, for example

@civic zephyr
I think something like this would look clearer
def subtotal(self):
return sum(item.get_price() * quantity for item, quantity in self.items())
for subtotal
k is item
v is quantity
but this one uses concrete names for what keys/values represent
it's a generator comprehension
sum's parentheses do the job

civic zephyr
vocal basin
height= not set
no
not grid
you have width=2 on the text field
you need to add height=something too
vocal basin
another thing you're missing is row += 1 at the end of the loop
for item in current_items:
...
row += 1
grid is easier there, I think
civic zephyr
vocal basin
and checkout is just missing .grid call
no, you don't need to do that
just use the current value of row with some offset
like it's already done in the code
row
row+1
row+2
row+3
it seems reasonable to have price at column 2
because it's already about prices
vocal basin
all the bN = assignments are unnecessary
vocal basin
use textvariable=self.data as the comment says
you will need textvariable functionality later
vocal basin
use `textvariable=self.data` as the comment says
self.data.set(str(self.cart.subtotal()))
Label(self, textvariable=self.data).grid(row=row, column=1)
instead of this
vocal basin
```py
self.data.set(str(self.cart.subtotal()))
Label(self, textvariable=self.dat...
the purpose of textvariable is the following:
later, when you add something to cart, label's contents should be updated
and, instead of managing complex callback logic, it's simpler to just bind the label to the variable instead

unless you want to say that the screenshot from before is wrong
I'm only basing my code on what I've seen in the screenshots

most situations don't involve row = next(rows)

other usecases are just .grid(row=next(rows)) on one line

yes, those two should be separate

vocal basin
you're refactoring towards incorrect use of `enumerate`
generally, use of values defined during iteration isn't a good practice
in almost any context, whatever, that's in for <here> in, would be treated as (re)defined in a loop not just assigned in a loop
figuring out what code, that's shadowing/redefining variables in such a manner, does is harder, so not a very good way to refactor
there is a way to, in some sense, elevate status of the (parts of) the loop's scope to the outer scope: for-else
for i, _ in enumerate(...):
...
else:
i = ...
