          "@type": "Answer",
          "text": "

You start the REPL by running the python command in your terminal without any arguments. This command opens an interactive session where you can type and execute Python code and get immediate feedback.

" } }, { "@type": "Question", "name": "What is the difference between script mode and interactive mode?", "acceptedAnswer": { "@type": "Answer", "text": "

In script mode, you run Python code from a file, and the interpreter executes it line by line. In interactive mode, you type code directly into the REPL environment and get immediate feedback.

" } }, { "@type": "Question", "name": "How can you terminate a Python REPL session?", "acceptedAnswer": { "@type": "Answer", "text": "

You can terminate the REPL by running exit() or quit(), raising SystemExit, or using keyboard shortcuts like Ctrl+D on Unix systems or Ctrl+Z then Enter on Windows. Any of these will return you to your system shell. In Python 3.13 and later, you can also use the exit and quit commands without parentheses.

" } }, { "@type": "Question", "name": "What is the purpose of the _ variable in the REPL?", "acceptedAnswer": { "@type": "Answer", "text": "

In a REPL session, the _ variable stores the result of the last evaluated expression. You can reuse it in new expressions without retyping the previous result.

" } }, { "@type": "Question", "name": "What are some benefits of using the Python REPL?", "acceptedAnswer": { "@type": "Answer", "text": "

You can use the Python REPL to quickly test ideas, debug code, explore Python syntax, introspect objects, and get help on modules or functions. The REPL gives you immediate feedback, which makes it a powerful learning and development tool.
