Understanding the double underscore name in Python

❓The double underscore name is a special variable in Python that is automatically set depending on how a file is executed.

❗When a Python file is executed directly, the double underscore name is set to 'double underscore main'.

✅The double underscore name can be used to determine if a file is being run directly or imported.

🔑Checking the value of double underscore name can allow code to be executed only when the file is run directly.

📚Importing a file in Python sets the double underscore name to the name of the imported file.

What is the purpose of the double underscore name in Python?

—The double underscore name is used to determine if a file is being run directly or imported.

How is the double underscore name set?

—When a Python file is executed directly, the double underscore name is set to 'double underscore main'. When a file is imported, it is set to the name of the imported file.

How can the double underscore name be used?

—By checking the value of the double underscore name, code can be executed conditionally, allowing certain code to run only when the file is run directly.

Is the double underscore name a reserved keyword in Python?

—No, the double underscore name is not a reserved keyword in Python. It is a special variable that is automatically set by the Python interpreter.

Can the double underscore name be modified in Python?

—No, the value of the double underscore name is automatically set by the Python interpreter and cannot be modified.
