Python 3.10 and above

In Python 3.10, they introduced the pattern matching.

Example from the Python documentation:

def http_error(status):
    match status:
        case 400:
            return Bad request
        case 404:
            return Not found
        case 418:
            return Im a teapot
        case _:
            return Somethings wrong with the internet

Before Python 3.10

While the official documentation are happy not to provide switch, I have seen a solution using dictionaries.

For example:

# define the function blocks
def zero():
    print You typed zero.n

def sqr():
    print n is a perfect squaren

def even():
    print n is an even numbern

def prime():
    print n is a prime numbern

# map the inputs to the function blocks
options = {0 : zero,
           1 : sqr,
           4 : sqr,
           9 : sqr,
           2 : even,
           3 : prime,
           5 : prime,
           7 : prime,
}

Then the equivalent switch block is invoked:

options[num]()

This begins to fall apart if you heavily depend on fall through.

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See Replacements for switch statement in Python?.
