如何在 Google Colab 中打开交互式 Python 提示？

Question

How does one open an interactive Python console/shell/prompt within Google Colab? Is it possible? An iPython prompt would be ideal but a regular prompt would suffice.

Also, it would be significantly more useful if the console's interpreter shared access to the variables/state with the Colab notebook's kernel.

Answer 1

!jupyter console --existing appears to hang with no output because it is waiting to acquire the GIL in the same process as the notebook's runtime that is executing the, magic. which isn't going to give it up until the. is done. For the same reason I don't think it's going to be easy to get a subprocess invocation to share state with the notebook's runtime. Obvs. you could program your own input() + eval() in a loop to simulate a py prompt that shared the env with your notebook.
