Note that this will only work with Python 3.10 and above.
The match case Statement in Python
A basic implementation of match case statements looks like an if statement
in Python.
>>> command = 'Hello, World!'
>>> match command:
... case 'Hello, World!':
... print('Hello to you too!')
... case 'Goodbye, World!':
... print('See you later')
... case other:
... print('No match found')
Hello to you too!It can simplify the flow control statements and make them a little bit more readable.
>>> def file_handler_v2(command):
... match command.split():
... case ['show']:
... print('List all files and directories: ')
... # code to list files
... case ['remove' | 'delete', *files] if '--ask' in files:
... del_files = [f for f in files if len(f.split('.'))>1]
... print('Please confirm: Removing files: {}'.format(del_files))
... # code to accept user input, then remove files
... case ['remove' | 'delete', *files]:
... print('Removing files: {}'.format(files))
... # code to remove files
... case _:
... print('Command not recognized')This is easier than a if-elif-else or using something like a dict().
