Using pwntools process interactive mode to control python3

I am trying to use pwntools to control a python3 session. Here is my code:
from pwn import process
r = process(['python3'])
r.interactive()
However, after I enter r.interactive(), when I type into the terminal, the python3 sub-process has strange reactions. At least I do not see my commands echoed back most of the times.
I also tried to call python3 in a bash session, but the same thing happens.
$ python3
Python 3.8.5 (default, Jan 27 2021, 15:41:15)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pwn import process
>>> r = process(['bash'])
[x] Starting local process '/usr/bin/bash'
[+] Starting local process '/usr/bin/bash': pid 119080
>>> r.interactive()
[*] Switching to interactive mode
echo hello
hello
echo this is bash
this is bash
python3
print(1)
print(2)
print(3)
exit
echo hello
File "<stdin>", line 5
echo hello
^
SyntaxError: invalid syntax
Why is this happening? Is it a bug in pwntools, or are there some configurations I overlook?

You need to specify the PTY in your shell, so like this:
$ python3
Python 3.9.2 (default, Feb 28 2021, 17:03:44)
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pwn import *; r = process(['python3'], stdin=PTY, raw=False); r.interactive()
[x] Starting local process '/usr/bin/python3'
[+] Starting local process '/usr/bin/python3': pid 2984281
[*] Switching to interactive mode
Python 3.9.2 (default, Feb 28 2021, 17:03:44)

Mac Pycharm Interpreter not working

I can't run my python programs in pycharm. I installed python3, pycharm and anaconda. I can open the project and write python code, but can't run the program in pycharm. I can use the terminal to run my program and it works fine. Any ideas how to use the right interpreter? Where can I find it? BTW I work with a mac.
When I try to add an interpreter I can add an Virtualenv Environment, Conda Environment or System Interpreter. When I click on System interpreter and choose one, it wont work. I tried to find my python version with the terminal and use it in pycharm, but it wont do anything.
Thats what I see:
entire screen
The icon also seems weird (red cross):

Greetings, Stefan

Inspect your conda python installation via:
$ conda info
Mine is: /root/miniconda, so basic grepping shows what pythons do I have:
root#d03107c14a07:/notebook# ls -al /root/miniconda/bin/ | grep python
-rwxrwxr-x 1 root root 129 Apr 16 16:20 ipython
-rwxrwxr-x 1 root root 129 Apr 16 16:20 ipython2
lrwxrwxrwx 1 root root 9 Apr 16 16:20 python -> python2.7
-rwxrwxr-x 1 root root 1689 Apr 16 16:20 python-config
lrwxrwxrwx 1 root root 9 Apr 16 16:20 python2 -> python2.7
-rwxrwxr-x 1 root root 10302 Dec 21 2016 python2.7
And running it like below shows it works:
root#d03107c14a07:/notebook# /root/miniconda/bin/python
Python 2.7.13 |Anaconda 4.4.0 (64-bit)| (default, Dec 20 2016, 23:09:15)

Anaconda is brought to you by Continuum Analytics.
Please check out: http://continuum.io/thanks and https://anaconda.org
>>>
We have the path, for me it's: /root/miniconda/bin/python
So, as we have it localized, we need to set it up with our Pycharm.
Go to Settings/Preferences and into Project interpreter, choose a settings wheel and Add - On the left you've got three options, choose Conda, your env might be found automatically, but if it isn't then you have the path to paste ;)

Change Apache Livy's Python Version

I have Apache Livy installed. Got this error when submit my code to Livy. How to change default Python Version in Apache Livy?

eshell starts python IDLE instead of running script when editing remotely

With Emacs 24.3.1, I get this when editing through Tramp/ssh in eshell:
/<remotepath> $ bash
/<remotepath> $ python test.py
hello world!
/<remotepath> $ exit
exit
/<remotepath> $ python test.py
Python 2.6.6 (r266:84292, Oct 12 2012, 14:23:48)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
The file test.py is:
print "hello world!"
Bash is version 4.1.2. Does anyone have any explanation for this behavior?

I don't know eshell, but my guess is you forget to pass the positional parameters when creating your alias:
# don't forget the quotes
# ▼ ▼
~ $ alias python '/path/to/alternate/python $*'
# ▲▲
# don't forget positional parameters

Unknown screen output of manually installed Python 2.7

I installed Python 2.7 today using:
./configure --prefix=/home/zhanwu/local --enable-shared --enable-profiling --with-pydebug
make install
Then I keep getting something like "[37745 refs]" on screen after each function call:
[zhanwu#cluster ~]$ ~/local/bin/python
Python 2.7.1 (r271:86832, Jun 16 2011, 17:45:05)

>>> import sys
[37745 refs]
>>> print 'test'
test
[37745 refs]
>>> sys.exit()
[18048 refs]
[zhanwu#cluster ~]$
What does those numbers mean? Anything wrong here and can I get rid of them?
uname -a result:
[zhanwu#cluster ~]$ uname -a

You get these because you configured the build with --with-pydebug. They denote the number of references Python is currently keeping track of. To get rid of them, configure without --with-pydebug.
