Another Introduction to Python Import

Demo 1: Simple module importing

This is a demo of simple module importing. Nothing fancy.

$ python main.py

module_foo: this is foo

Demo 2: Intra-package importing

This is a broken package importing.

$ python main.py

import pkg_foo.module_foo
Traceback (most recent call last):
  File "main.py", line 1, in <module>
    from pkg_foo.module_foo import print_foo
  File "/Users/nanwang/Codes/nan-wang/python-meetup-hangzhou-202203/demo2/pkg_foo/module_foo.py", line 4, in <module>
    from module_bar import bar_var
ModuleNotFoundError: No module named 'module_bar'

🗝 Solution

Demo 3: Package importing

This is another broken package importing.

$ python scripts/main.py

Traceback (most recent call last):
  File "scripts/main.py", line 1, in <module>
    from pkg_foo.module_foo import print_foo
ModuleNotFoundError: No module named 'pkg_foo'

###🗝 Solution

Demo 4: Jina importing

This is a demo how Jina import customized executors.

$python main.py
