The video tutorial explains how to use the Python REPL for executing code line by line, defining functions, and testing code. It covers using the interactive mode to test Python files and demonstrates how to open and test Python modules using the REPL. The tutorial highlights features like the i flag for interactive mode and the M flag for module testing, providing practical examples with variables, functions, and modules like random and logger.

What does the Python REPL allow you to do?

• Create graphical user interfaces

• Manage Python package installations

• Compile Python code into machine code

• Execute Python code line by line

How can you exit the Python REPL?

• By pressing Ctrl+C

• By using the 'quit' or 'exit' function

• By closing the terminal window

• By typing 'stop'

What is the purpose of using the 'i' flag with the Python command?

• To run Python scripts in silent mode

• To open a Python file in interactive mode

• To install Python packages

• To compile Python code

Which feature allows you to recall previous commands in the REPL?

• Using the 'back' command

• Typing 'recall'

• Pressing the upper arrow key

• Using the 'history' command

What does the 'M' flag do when used with the Python command?

• It compiles a Python script

• It opens a Python module

• It runs a Python script in debug mode
