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. switchDict[type(varX)]() For this you would need to move the construction of the dictionary to after all the functions are defined. 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.The switch statement could be extended to allow multiple values for one section (e.g. case ‘a’, ‘b’, ‘c’: …).
