如何从Python代码放入REPL(读取，评估，打印，循环) [英] How to drop into REPL (Read, Eval, Print, Loop) from Python code

问题描述

即使脚本是从命令行启动的，有没有办法以编程方式强制Python脚本在执行的任意时刻掉入REPL?

Is there a way to programmatically force a Python script to drop into a REPL at an arbitrary point in its execution, even if the script was launched from the command line?

我正在编写一个快速而肮脏的绘图程序，我想从stdin或文件中读取数据，对其进行绘图，然后放入REPL中以自定义绘图.

I'm writing a quick and dirty plotting program, which I want to read data from stdin or a file, plot it, and then drop into the REPL to allow for the plot to be customized.

推荐答案

您可以尝试对python使用交互式选项:

You could try using the interactive option for python:

python -i program.py

这将执行program.py中的代码，然后转到REPL.您在program.py顶层定义或导入的所有内容都将可用.

This will execute the code in program.py, then go to the REPL. Anything you define or import in the top level of program.py will be available.
