Using the “in” operator in Python 3.10 Match Case

Is there a “in” operator in python 3.10 Match Case like with if else statements

if "n" in message:

the in operator doesn’t work in match case

match message:
    case "n" in message:

This doesn’t work. How to have something like the “in” operator in Match-Case.

Answer

In match-case we can use the split() method on the message string.

Example:

def match_case_with_if(command):
    match command.split():
        case [*command_list] if 'install' in command_list:
            print(f"Hey you are installing {command_list[-1]}....")
        case [*command_list] if 'uninstall' in command_list:
            print(f"Are you sure you want to uninstall {command_list[-1]} ?")


match_case_with_if('pip install numpy')
# Output: Hey you are installing numpy....
match_case_with_if('pip uninstall numpy')
# Output: Are you sure you want to uninstall numpy ?

Here, the string can be split into a list and if condition can be applied on it’s contents. Hope this helps!!
