Use functions or APIs from external libraries to develop a computer program : Name and Main

The video tutorial explains the significance of the __name__ and __main__ variables in Python, demonstrating how they help determine if a file is being run as a script or imported as a module. It covers creating and running Python files, using __name__ to check script execution, and importing functions. Practical applications, such as using a script for web scraping, are discussed, along with testing methods. The tutorial emphasizes the commonality of these practices in Python programming.

What is the output when a Python file is run as a program versus when it is imported?

How can you test if a Python file is functioning correctly when imported?

What are some common practices when writing Python scripts that may be reused as modules?
