如何将标准输入发送到 IPython？

Question

I'm having trouble trying to send data through stdin to IPython, it seems that EOF is interpreted as an exit command for ipython ?

Example:

echo '"hello"' |ipython

Python 3.9.2 (default, Feb 28 2021, 17:03:44)
Type 'copyright', 'credits' or 'license' for more information
IPython 8.2.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: Out[1]: 'hello'

In [2]: Do you really want to exit ([y]/n)?

And the process quits without me doing anything else.

Is there a parameter to set or something ?

---

Edit: To make the context clearer, the real scenario where I want to do this is the following:

program1 | ipython -i -c "%run script"

program1 would output something (a json), and ipython would run a script that load the thing into something I can use, then leave me to a IPython interpreter where I can play with it.

Answer 1

Same as comment. your question is quite unclear.

Maybe pipe some python command to a python interperter?

try this

$ (echo 'a=123' && cat ) | ipython -i
Python 3.6.9 (default, Mar 15 2022, 13:55:28)
Type 'copyright', 'credits' or 'license' for more information
IPython 7.16.3 -- An enhanced Interactive Python. Type '?' for help.

In [1]:
In [2]: print(a)
123

this will execute a=123 and make python into interative mode which take your keyboard input
