Mutating a python incoming object by reference

Question

I have a legit situation like this where I need to implement a method that changes the incoming object itself (convert list into dict) def f(l): # f is a function that receives a list as input pass # Implement this x = ['Hello', 'World'] f(x) print(x) # x is now a dict {'hello':'world'} How will you implement the above f() ? The key thing is upon calling f() the incoming object itself must be mutated into different type. Note: Genuine answers welcome instead of questioning the situation.

Answer 1

Python does not have a way to do what you want. You cannot change the binding of a variable in the calling context from within a function. Of course, "cannot" has to be qualified: Python has many introspection capabilities, even letting you examine the calling stack, and the globals and locals in calling frames. But I strongly recommend against going that way. I know you said you didn't want people to question the need for this, but I can't help thinking there is a better way to solve the problem.
