If you type andunderscore in the name of a function

defpublic_`# I want def public_ip():

it deletes the current line and returns back at the start of the history.

after I have typed a dot it shows the possible completions but when I digit acapital P it deletes the current line and returns back at the start of the history.

http=urllib3.P# I want http = urllib3.PoolManager()

Note
Actually this is a big problem ofbpython-cursesalso on Linux (I've tested it on my Fedora 32, last version) and indeed it is deprecated, but the crucial point is that the realbpython is running on Linux but not on Windows.
