Final answer:
Python code can indeed be executed by typing it in at the Python command line, which is useful for learning and debugging purposes.
Step-by-step explanation:
True, Python code can be executed by typing it in at the Python command line, also known as the Python interpreter or the REPL (Read-Eval-Print Loop). This enables users to write and execute their code line by line, which is particularly useful for learning, experimenting, and debugging. When you start the Python interpreter, you're able to input Python code directly, and it will execute immediately, displaying any output to the screen. This instant feedback can be very helpful for beginners who are trying to understand how different pieces of code work.
