标准python解释器有一个vi命令模式？

pip install prompt_toolkit

from prompt_toolkit import PromptSession
from prompt_toolkit.history import FileHistory
from prompt_toolkit.auto_suggest import AutoSuggestFromHistory
from prompt_toolkit.contrib.python_input import PythonInput
from prompt_toolkit.key_binding.manager import KeyBindingManager
from prompt_toolkit.shortcuts import clear

def main():
    session = PromptSession(
        history=FileHistory('history.txt'),
        auto_suggest=AutoSuggestFromHistory(),
        key_bindings_registry=KeyBindingManager.registry,
    )

    while True:
        try:
            text = session.prompt('>>> ', input_processors=[PythonInput()])
            code = compile(text,<input>', 'exec')
            exec(code)
        except KeyboardInterrupt:
            clear()
        except EOFError:
            break
        except Exception as e:
            print(f'Error: {e}')

if __name__ == '__main__':
    main()
