Building Python Command Prompt Interface

Question

Is there a way to build a simple Python Command Prompt Interface. It only needs to input text and Output something.

In the end the Interface should something look this:

sample

From Pycharm 2017 i get these error.

Traceback (most recent call last): File "C:/Users/Main/Desktop/Py Sandbox/Keylogger/test.py", line 4, in user_input = prompt('>') File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\shortcuts.py", line 548, in prompt eventloop=eventloop) File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\shortcuts.py", line 576, in run_application output=create_output(true_color=true_color)) File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\shortcuts.py", line 118, in create_output return Win32Output(stdout) File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\terminal\win32_output.py", line 80, in init info = self.get_win32_screen_buffer_info() File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\terminal\win32_output.py", line 172, in get_win32_screen_buffer_info raise NoConsoleScreenBufferError prompt_toolkit.terminal.win32_output.NoConsoleScreenBufferError: No Windows console found. Are you running cmd.exe?

And from the default Python IDLE i get this eroor:

Traceback (most recent call last): File "C:/Users/Main/Desktop/adusgisdhui.py", line 4, in user_input = prompt('>') File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\shortcuts.py", line 548, in prompt eventloop=eventloop) File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\shortcuts.py", line 576, in run_application output=create_output(true_color=true_color)) File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\shortcuts.py", line 118, in create_output return Win32Output(stdout) File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\terminal\win32_output.py", line 80, in init info = self.get_win32_screen_buffer_info() File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\terminal\win32_output.py", line 162, in get_win32_screen_buffer_info self.flush() File "C:\Users\Main\AppData\Local\Programs\Python\Python35\lib\site-packages\prompt_toolkit\terminal\win32_output.py", line 288, in flush self.stdout.flush() AttributeError: 'NoneType' object has no attribute 'flush'

You don't need a separate module. The `input` function is a built-in. — Arya McCarthy, May 12 '17 at 18:08

Are you really wanting to build a virtual terminal with a user interface that looks rather identical to the windows/python command interface? Or just get user input from the windows command prompt? — chickity china chinese chicken, May 12 '17 at 18:11

Here is a great article about building command line interfaces for you python programs CLI Python. One of the methods is to use the prompt_toolkit:

from prompt_toolkit import prompt

while 1:
    user_input = prompt('>')
    print(user_input)

This will then continually ask the user for input. It also has features such as command history and auto-suggestion.
