Question

我是Python的新手，我正在尝试编写一个基本上用作闹钟的程序。我提示用户在特定时间设置闹钟，然后当该时间发生时，将播放从txt文件中的YouTube视频列表中获取的YouTube视频。但是，我不太清楚为什么我会收到这个错误，因为我仍然对python语法很不熟悉。这是我的代码：

import time

def addVideo():
    videoToAdd = raw_input("Enter the url of the video to add: ")
    with open('alarmVideos.txt', 'w') as f:
        f.write(videoToAdd + '\n')

alarmTime = raw_input("When would you like to set your alarm to?: \nPlease use this format: 01:00\n")

localTime = time.strftime("%H:%M") 

addVideo = raw_input("Would you like to add a video to your list? (y/n): \n")

if addVideo == 'y' or addVideo == 'n':
    addVideo()


print "Your alarm is set to:", alarmTime

我收到了这个错误：

Traceback (most recent call last):
  File "C:\Users\bkrause080\Desktop\Free Time Projects\LearningPythonProjects\alarmClock.py", line 15, in <module>
    addVideo()
TypeError: 'str' object is not callable

如果在用户输入y / n后是否有助于发生此错误，他们是否想要将视频添加到其列表中。谢谢你的帮助！

Answer 1

问题是因为你将函数名和变量命名为同名（addVideo），Python＆＃39; confuse＆＃39;函数和变量。重命名其中任何一个：

import time

def addVideo():
    videoToAdd = raw_input("Enter the url of the video to add: ")
    with open('alarmVideos.txt', 'w') as f:
        f.write(videoToAdd + '\n')

alarmTime =raw_input("When would you like to set your alarm to?: \nPlease use this format: 01:00\n")

localTime = time.strftime("%H:%M")

add_Video = raw_input("Would you like to add a video to your list? (y/n): \n")

if add_Video == 'y' or add_Video == 'n':
    addVideo()


print( "Your alarm is set to:", alarmTime)

输出：

When would you like to set your alarm to?: 
Please use this format: 01:00

Would you like to add a video to your list? (y/n): 
n
Enter the url of the video to add: grg
Your alarm is set to:

Answer 2

您正在使用字符串addVideo = raw_input("Would you like ...")

覆盖函数addVideo（）

您需要重命名该功能或变通。

addVideoResult = raw_input("Would...")

if addVideoResult == 'y' or addVideoResult == 'n':
    addVideo()

Answer 3

由于要覆盖函数，因此raw_input("Would you like to add a video to your list? (y/n): \n")需要不同的名称引用：

run = raw_input("Would you like to add a video to your list? (y/n): \n")
if run == 'y' or run == 'n':
    addVideo()

TypeError'st'对象不可调用 - Python
