No, Python doesn't even do that, because Python variables aren't names for storage locations to begin with. They're namespace bindings. Passing a variable to a Python function means transferring a namespace binding from the caller's namespace to the function's local namespace.

What is a namespace binding? Can you explain at a low level what that means?

Compare a variable assignment in C and Python.

In C:

  int i = 17;
Means "set aside one int's worth of storage and fill it with the bit pattern for the number 17".

In Python:

  i = 17
means "create an int object with the value 17 and bind it in the current namespace dictionary to the name i".

The semantics are identical.

If you think this, I'm confused about what you mean by "semantics".
