Literacy Sticker---about if __name__ = = ' __main__ ' in Python

For __name__ variables in Python, the value of the __name__ variable varies depending on how the Python file is called. If I had a Python script called hello_world.py, when I was aiming to run the file "Python hello_world.py" directly, the value for hello_world.py's __name__ variable was "__ Main__ ". But when we put hello_world.py as a module by introducing another module to "Import Hello_world", the value of __name__ variable in hello_world.py is the python filename "hello_ World ".

Example:

1. Python script named Hello_world

2. When running the hello_world.py Python script directly

3. After the hello_world.py module is introduced into the hello_world01.py script

4. Script to run hello_worlld01.py
