Python Shell not showing input code

### What did you expect to happen?

When opening a python buffer I expect the code I manually input on the buffer to work fine (here showing additional characters).

On the other hand, when sending the whole buffer, I expect the code to show up in the buffer (the input as well as the output). Something similar to the behavior obtained with SLIME.

### What actually happened?


### Describe your attempts to resolve the issue

I tried to change the python configuration to use --simpe-args, and to change the interpreter from python to python but no option is working at the moment.

### Steps to reproduce

1. Open emacs
2. Load virtualenv with Pyvenv-workon
3. Open code
4. Open python buffer
5. Send code with C-c C-c
