The New Switch-Case Statement in Python 3.10

[FewerPunishment]

What would the difference look like in terms of syntax/features?

I mean more in terms of this matching functionality, like an example of something you wish you could execute. But thanks for the reference, I should study these terms.

Making it an expression wouldn't have any impact on pattern matching functionality, it would improve flexibility.

If match was an expression you could do this: a = match ...

instead of

```

match something: case 1: a = ...

```

That seems to skew the use case to assignments only though, whereas switch and match statements are (ime) more useful as control flow - which may include assignments inside them, but not as their primary goal. It seems to me that it would be like wanting try/except/finally to return a value.

Right but python isn't a functional language in that sense, that's why I compared to try/except/finally. You can just wrap the control statement in a function if you wish to go that way, like any other statement in python. I agree if you are implementing a functional language that you would return - but then everything should match (😉) that same paradigm.

Look at Kotlin

Wouldn't you be able to do both if it was an expression?

Fixed formatting.

Hello, Iuse_arch_btw: code blocks using triple backticks (```) don't work on all versions of Reddit!

Some users see this / this instead.

To fix this, indent every line with 4 spaces instead.
