The from Statement

By contrast, because from also copies names from one file over to another scope, it allows us to use the copied names directly in the script without going through the module (e.g., printer):

>>> from module1 import printer            # Copy out one variable
>>> printer('Hello world!')                # No need to qualify name
Hello world!

This has the same effect as the prior example, but because the imported name is copied into the scope where the from statement appears, using that name in the script requires less typing: we can use it directly instead of naming the enclosing module.

As you’ll see in more detail later, the from statement is really just a minor extension to the import statement—it imports the module file as usual, but adds an extra step that copies one or more names out of the file.
