从控制台 Python3 中删除 input() 文本

Question

I want to clear the line of text created after the input() function. I've tried \033[a, \r, end='' but either I'm doing it wrong or it doesn't work. Is there a better way:

Code is:

rawguess = input('Enter a 5 letter word: ')
print('words go here')

I've tried:

rawguess = input('\033[A' + 'Enter a 5 letter word: ' + '\033[A')
print('words go here')

rawguess = input('Enter a 5 letter word: ')
print('\rwords go here')

rawguess = input('Enter a 5 letter word: ')
print('\r', end='')
print('words go here')

And other variations of these three but nothing's worked so far.

I didn't know this before, but apparently Windows now supports Console Virtual Terminal Sequences , which include using ESC [ <n> A to move the cursor up (like on *nix). So we can call the Win32 API with ctypes.windll and enable Virtual Terminal Sequences, which will allow us to use '\x1b[1A' .

import sys

# Only do this on Windows, so that *nix users
# can also run the program without errors
if sys.platform.startswith('win'):
    import ctypes
    from ctypes.wintypes import *

    STD_OUTPUT_HANDLE = -11
    ENABLE_VIRTUAL_TERMINAL_PROCESSING = 4

    kernel32 = ctypes.windll.kernel32

    h = kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
    m = DWORD()
    kernel32.GetConsoleMode(h, ctypes.pointer(m))
    m.value |= ENABLE_VIRTUAL_TERMINAL_PROCESSING
    kernel32.SetConsoleMode(h, m)

rawguess = input('Enter a 5 letter word: ')
print('\x1b[1A' + 'words go here')

Well I just found a piece of dark magic allowing you to enable terminal controls in Python:

import subprocess
subprocess.run("", shell=True)
input('Enter a 5 letter word: ')
print('\x1b[1A' + 'words go here       ')
