scoping has nothing to do with this.

in Python, a variable is a name associated with an object.

the from-import statement creates new names, in the current
module, which points to existing objects from another module.

assignment also creates new names in the current module.

the above statement doesn't modify the original "x" object;
it creates a new list, and gives it a name.

if the introductory book you used to learn Python didn't explain
this, ask for a refund ;-)

reading the following articles might help:
