有没有办法提示用户输入并在设置的字符数后继续，以避免在 python 3 中等待回车键？

Question

我正在尝试编写一个 python 打字测试，它在 60 秒的定时 while 循环中显示列表中的 5 个字母单词。如果用户在每个键入的单词后按回车键，一切都会正常，但这允许退格，这不是我的目标。在没有按下回车键的情况下输入 5 个键（包括箭头键和退格键）后 input() 是否能够继续？就像按下回车键一样继续下一个单词？

import time
import random

                           
t_end = time.time() + 60    # Set timer for 60 seconds


correct = 0
incorrect = 0
attempts = 0
accuracy = 0

words=["buggy", "Help!", "etc.."]    #TODO: put lots of 5 character words a list

while time.time() < t_end:
    for word in random.sample(words, 1):
        print(word, end=" ")
        wpm_count += 1
        user_txt = input("  ")
        if (user_txt == word):
            correct += 1
            
        else:
            incorrect += 1

#Calculate and display results
accuracy = (correct / attempts ) * 100
print("=-=-=- Results: -=-=-= \nCorrect: " + str(correct) + " \nErrors: " + str(incorrect) + " \n Total WPM: " + str(attempts) + "\nAccuracy: " + str(accuracy) )

是的，您可以使用 curses 模块中的 getch() 函数来读取键盘输入，而无需用户在每个单词后按 Enter 键。这是使用 getch() 实现代码的示例：

import time
import random
import curses

t_end = time.time() + 60    # Set timer for 60 seconds

correct = 0
incorrect = 0
attempts = 0
accuracy = 0

words=["buggy", "Help!", "etc.."]    #TODO: put lots of 5 character words a list

# initialize the curses module
stdscr = curses.initscr()
curses.cbreak()
stdscr.keypad(True)

# loop until the timer runs out
while time.time() < t_end:
    for word in random.sample(words, 1):
        stdscr.addstr(word + " ")
        stdscr.refresh()
        
        # read input without requiring Enter
        user_txt = ""
        while len(user_txt) < len(word):
            c = stdscr.getch()
            if c == curses.KEY_BACKSPACE:
                user_txt = user_txt[:-1]  # remove last character
            elif c >= 32 and c <= 126:  # printable characters
                user_txt += chr(c)
            elif c == 27:  # escape key
                break
        
        # compare input to expected word
        attempts += 1
        if user_txt == word:
            correct += 1
        else:
            incorrect += 1

# cleanup curses module
curses.nocbreak()
stdscr.keypad(False)
curses.echo()
curses.endwin()

# calculate and display results
accuracy = (correct / attempts ) * 100
print("=-=-=- Results: -=-=-= \nCorrect: " + str(correct) + " \nErrors: " + str(incorrect) + " \n Total WPM: " + str(attempts) + "\nAccuracy: " + str(accuracy) )
