This won't work if v is something like a generator, right?

🙌

I should take a look at that module to see what's there. I keep forgetting about it and while you're right that folks that really need it will likely already have numpy around it's good to know what's a single import away...

Hehehe, that's only until those SEO farmers write sh177y articles and outrank me :)

By the time the C++ is compiled, my Python script has finished running 🤪

Yeah, this is O(n^2) but the focus of this drop is to showcase the behaviour of deque and not suggest that this is the best possible implementation of a sliding window in Python.

When I'm feeling fancy, I define some methods in a more “functional” way.

I just have fun writing code like this for myself 🤪

👇 yay or nay?

We'll race in reverse. Last to submit, wins.

I don't have 0 ideas. I have too many ideas given the 3 proposal limit. I just have to sit down and submit them :)

And I'm still at 0 proposals submitted :P

Oh this is fun :D

Also, remember:

⛔️ NEVER use `assert` with security-related or sensitive checks!

Like, never.

That's a sure-fire way of running into problems because `assert`s can be “turned off”...

And you don't want someone stealing your bank details because an `assert` didn't run!

In front of the expression, add a comma and then a custom string.

That custom string is the error message that will show up in front of the `AssertionError` if the assertion fails during runtime.

Make sure it's a good error message with helpful context!

I was thinking about those 6, yeah: upper, lower, title, capitalize, casefold, swapcase

Oh no! That's the type of bug I would take ages to find...

For example, ALL functions are Truthy, regardless of what they do.

Even a function that does nothing is Truthy.

```py
def foo():
pass

print(bool(foo)) # True
```

(By the way, you can check the Truthy/Falsy value of something with the built-in `bool`.)

Then, all other values are “Truthy”.

E.g., the empty list is Falsy but any other list is Truthy.

So, you can use the Truthy/Falsy value of a list to check if it's empty.

This is very idiomatic in Python.

Some other types don't have Falsy values!
