- emacs -q
- (setq python-shell-interpreter "ipython3")
- M-x run-python
- Enter 1 + 2 into the IPython prompt.

After hitting Enter, the '2' displays twice:

Python 3.8.6 (default, Sep 23 2020, 13:54:27) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.17.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: 1 + 2
1 + 22
Out[1]: 3

Not only that, it grows progressively weirder:

In [1]: 1 + 2
1 + 22
Out[1]: 3

This is solved by adding the following extra argument to ipython:

(setq python-shell-interpreter "ipython3"
      python-shell-interpreter-args "--simple-prompt")

Should the defaults in python.el be changed?

No, the defaults are good.  But there's a pitfall: if you change the
interpreter from "python" to the fancier "ipython", you need to add the
extra "--simple-prompt" argument.

Ah, I see.  I've now amended the doc string of
`python-shell-interpreter' to mention this.  And I think that should be
sufficient here, and I'm closing this bug report.
