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.
