return switcher[command[1]](data.id) if command[1] in switcher else funcE() Also, you can replace if not (data.message is None) with if message and combine it with data.message [0] == "/". As pointed out by @Mark Bailey, since you're already checking if command [1] is in switcher, you can remove the second if statement altogether.In Python 3.10 and later, Python has a special match and case as an alternative to the Switch statement. Now let’s look at ways to implement the Switch case in detail. 1. Using if-elif-else. The if-elif-else statement can easily be used as a switch statement in the case of python. With the if-elif-else statement, you can compare values to an ...

The switch statement could be extended to allow multiple values for one section (e.g. case ‘a’, ‘b’, ‘c’: …). Another proposed extension would allow ranges of values (e.g. case 10..14: …). These should probably be post-poned, but already kept in mind when designing and implementing a first version.
