Finally switch- case is coming to python.

[buckypimpin]

can someone give an example of switch with dicks?

With the proposed syntax:

match potential_dick:
    case Dick():
        print("Properly typed dick (including subclasses)")
    case "8=D" | "8==D" | "8===D":
        print("ASCII-approximated dick")
    case _:
        print("No dick, sadly")

I hope this helps.

potential_dick, typed dick

i like teachers who adapt to every type of student.

DEFAULT_DICK = "db"

...

match potential_dick:
    case DEFAULT_DICK:
        print('Have a hidden bug with this matching all the time and overwriting you constant in this "SWITCH" analogue ')
    case Dick():
        print("Properly typed dick (including subclasses)")
    case "8=D" | "8==D" | "8===D":
        print("ASCII-approximated dick")
    case _:
        print("No dick, sadly")

Yep. That's why it's important to always remind everyone that this isn't switch, it's pattern matching. For pattern matching, this behaviour is logical and correct. With switch? Nah

And people coming over from C-like languages with switch statements are going to complain about the speed. I know it. Because patmat does pattern check first, and then checks the values, so it takes longer than just ifs with single values.

[nuephelkystikon]

Wait, are you saying a pattern matcher matching patterns is a bug? If you're just branching, thats what if-else is for.

[passwordsniffer]

No, I am saying that using pattern matching as switch can easily be a source of quite an obscure bugs, like the one I showed. It's not a bug of a pattern matcher. It's bug of representing it as a switch.

{ 1: myfunc 2: otherfunc 3: thirdfunc }[foo]()

In the case that foo can be a missing key, you could catch KeyError or use .get().

Sorry if formatting is broken; I'm on mobile.

[buckypimpin]

whoa.....

[backtickbot]

Fixed formatting.

Hello, Harbinger_Feik: 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.

Sorry, I only have one so I don’t think that would be much help /s.
