Why doesn’t Python have a switch statement?

What is the reason Python doesn’t have switch statement?

Answer [by Keltia]: Why doesn’t Python have a switch statement?

Probably because, like in Perl, you don’t need it to express the same thing?

I admit I appreciate Ruby having one though, it makes code cleaner than a series of if..elsif..else. YMMV :)

How can I increment a variable without exceeding a maximum value?

I am working on a simple video game program for school and I have created a method where the player gets 15 health points if that method is called. I have to keep the health at a max of 100 and with my limited programming ability at this point I am doing something like this.

public void getHealed(){ if(health <= 85) health += 15;…

How to: Is there any significant difference between using if/else and switch-case in C#?

Is there any significant difference between using if/else and switch-case in C#?

What is the benefit/downside to using a switch statement vs. an if/else in C#. I can’t imagine there being that big of a difference, other than maybe the look of your code.

Is there any reason why the resulting IL or associated runtime performance would be radically different?

Switch statement fallthrough in C#?

Switch statement fallthrough is one of my personal major reasons for loving switch vs. if/else if constructs. An example is in order here:

static string NumberToWords(int number) { string[] numbers = new string[] { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; string[] tens = new string[] { "", "", "twenty", "thirty", "forty",…

How to: Using {} in a case statement. Why?

Using {} in a case statement. Why?

What is the point with using { and } in a case statement? Normally, no matter how many lines are there in a case statement, all of the lines are executed. Is this just a rule regarding older/newer compilers or there is something behind that?

int a = 0; switch (a) { case 0:{ std::cout << "line1\n"; std::cout << "line2\n"; break; } }

and

int a = 0; switch (a) {…

Why does Java switch on contiguous ints appear to run faster with added cases?

I am working on some Java code which needs to be highly optimized as it will run in hot functions that are invoked at many points in my main program logic. Part of this code involves multiplying double variables by 10 raised to arbitrary non-negative int exponents. One fast way (edit: but not the fastest possible, see…

Multiple Cases in Switch:

I believe I’ve seen this somewhere, but I don’t recall if it was a different language, or if I just can’t remember the syntax well.

Is there a way to fall through multiple case statements without stating case value: repeatedly?

I know this works:

switch (value) { case 1: case 2: case 3: //do some stuff break; case 4: case 5: case 6: //do some different stuff break;…
