■ import statement and as

◆import Prepare directories and files like this.

lesson_package
 ├ __init__.py

    return (word + '!') * 2

lesson.py


import lesson_package.utils

r = lesson_package.utils.say_twice('hello')
print(r)

result


hello!hello!

You can load functions in other files by writing the full path like ʻimport lesson_package.utils`.

◆ from and import

import lesson_package.utils

Is

from lesson_package import utils

You can write it like this. In that case,

lesson.py


from lesson_package import utils

r = utils.say_twice('hello')
print(r)

It can be used like this.

◆as

lesson.py


from lesson_package import utils as ut

r = ut.say_twice('hello')
print(r)

By specifying a character string with as, you can call it with your favorite character string.
