Question

创建一个程序，用于计算用户正确键入字母所需的时间。它不会停止计时器，直到他们正确键入它，如果他们犯了错误，它将显示一条消息，他们将不得不尝试再次键入它。一旦他们成功地设法输入正确的字母，它将告诉他们花了多长时间，然后问他们是否想再次尝试，看看他们是否可以打败他们以前的时间。

我成功完成了第一部分：

import time

starttime = time.time()

def ask_question1():
answer1= input("Type in the alphabet as fast as you can then press enter: ")
return answer1

if __name__=="__main__":
    answer1=ask_question1()
    while answer1 != "abcdefghijklmnopqrstuvwxyz":
        print("You made a mistake. ")
        answer1=input("Try again: ")

endtime=time.time()
print("It took you ",round(endtime-starttime, 2), " seconds")

但是我无法再问这个问题并重复这个过程。

Answer 1

您似乎需要拨打ask_question1而不是answer1=input("Try again: ")

Answer 2

使用raw_input（）而不是input（），这会将其作为字符串返回。

import time

starttime = time.time()

def ask_question1():
    return raw_input("Type in the alphabet as fast as you can then press enter: ")

if __name__=="__main__":
    while ask_question1() != "abcdefghijklmnopqrstuvwxyz":
        print("You made a mistake. ")

endtime=time.time()
print("It took you ",round(endtime-starttime, 2), " seconds")

Answer 3

这应该有用;使用raw_input并递归调用函数。

import time

starttime = time.time()

def ask_question1():
    answer1= raw_input("Type in the alphabet as fast as you can then press enter: ")
    return answer1

if __name__=="__main__":
    answer1=ask_question1()
    while answer1 != "abcdefghijklmnopqrstuvwxyz":
        print("You made a mistake. ")
        answer1=ask_question1()

    endtime=time.time()
    print("It took you ",round(endtime-starttime, 2), " seconds")

Answer 4

import time

starttime = time.time()

def ask_question1():
    return raw_input("Type in the alphabet as fast as you can then press enter: ")

if __name__=="__main__":
    while ask_question1() != "abcdefghijklmnopqrstuvwxyz":
        print("You made a mistake.Try again: ")

endtime=time.time()
print("It took you ",round(endtime-starttime, 2), " seconds")

Answer 5

你可以尝试这样的事情。

Answer 6

import time
starttime = time.time()

def ask_question1():
    answer1= raw_input("Type in the alphabet as fast as you can then 
press enter: ")
    return replying_question1(answer1)

def replying_question1(answer):
    while answer in "abcdefghijklmnopqrstuvwxyz":
        endtime=time.time()
        print("It took you ",round(endtime-starttime, 2), " seconds")
        return round(endtime-starttime, 2)
    print("You made a mistake. ")
    ask_question1()
if __name__=="__main__":
    ask_question1()

输出将是：失败：

Type in the alphabet as fast as you can then press enter: 3
You made a mistake.

正确：

Type in the alphabet as fast as you can then press enter: e
('It took you ', 3.32, ' seconds')

而不是raw_input只有在使用python 3时才能使用input（）。

Answer 7

不需要ask_question1功能，您可以使用input 在Python 3中或在Python 2中raw_input。
您无需编写"abcdefghijklmnopqrstuvwxyz"，您可以使用 Python 2中的string.lowercase或Python中的string.ascii_lowercase
你可以永远做一段时间;）发牢骚while True并使用brake 退出循环。

Python 2：

import time
import string

if __name__=="__main__":
    starttime = time.time()
    answer1 = raw_input("Type in the alphabet as fast as you can then press enter: ")
    while True:
        if answer1 != string.lowercase:
            print("You made a mistake. ")
            answer1 = raw_input("Try again: ")
        else:
            endtime = time.time()
            print("It took you " + str(round(endtime-starttime, 2)) + " seconds")
            break

Python 3：

import time
import string

if __name__=="__main__":
    starttime = time.time()
    answer1 = input("Type in the alphabet as fast as you can then press enter: ")

    while True:
        if answer1 != string.ascii_lowercase:
            print("You made a mistake. ")
            answer1=input("Try again: ")
        else:
            endtime=time.time()
            print("It took you ",round(endtime-starttime, 2), " seconds")
            break
