The main difference is that switch despatches immediately to the case concerned, typically via an indexed jump, rather than having to evaluate all the conditions that would be required in an if-else chain, which means that code at the end of the chain is reached more slowly than code at the beginning.. That in turn imposes some restrictions on the switch statement …

Also, it would be recommended to not use string as the name of a function, it conflicts with string which is a standard module. It would be better to use another name, like string_type or so. Here’s a little trick you can use to emulate switch/case statements in Python using dictionaries and first-class functions.

Step 2: The evaluated value is matched against all the present cases. Step 3A: If the matching case value is found, the associated code is executed. Step 3B: If the matching code is not found, then the default case is executed if present.
