Switch-Case Statements Are Coming to Python

Python 3.10 is beginning to fill-out with plenty of fascinating new features. One of those, in particular, caught my attention — structural pattern matching — or as most of us will know it, switch/case statements.
Switch-statements have been absent from Python despite being a common feature of most languages.

Back in 2006, PEP 3103 was raised, recommending the implementation of a switch-case statement. However, after a poll at PyCon 2007 received no support for the feature, the Python devs dropped it.
Fast-forward to 2020, and Guido van Rossum, the creator of Python, committed the first documentation showing the new switch-statements, which have been named Structural Pattern Matching, as found in PEP 634.
What we have here is much more than a simple switch-case statement, however (hence match-case), as we will see soon.

python
example:

http_code = "418"
match http_code:
    case "200":
        print("OK")
        do_something_good()
    case "404":
        print("Not Found")
        do_something_bad()
    case "418":
        print("I'm a teapot")
        make_coffee()
    case _:
        print("Code not found")

there was a lot of alternative for switch case till now but at last switch case is getting added in python 3.10.![]
