据我所知，一旦它开始在该进程中运行另一个脚本，就没有简单的方法来连接到现有的python进程.

As far as I know there is no easy way to connect to an existing python process once it is started to run another script within this process.

您可以选择在交互式会话中工作，例如在IPython中.在那里你可以创建你的情节并在你前进时对其进行操纵.

The option you have is to work in an interactive session, e.g. within IPython. There you may create your plot and manipulate it as you advance.

例如

   1: import matplotlib.pyplot as plt
   2: import numpy as np
   3: fig, ax = plt.subplots()
   4: line, = ax.plot([1,3,2])
   5: plt.ion()
   6: plt.show()                   # shows the figure
   7: line2, = plt.plot([2,2,1])   # inside the figure shows another line
   8: line.remove()                # removes the first line from the figure
