TypeError：“模块”对象不可调用 - 使用日期时间

Question

抱歉，没有找到任何其他解决方法，所以我创建了一个新问题。 我正在尝试运行一个将当前小时、分钟和秒打印到屏幕上的代码。我用来执行此操作的代码是：

def time():
    import datetime
    import time
    time.sleep(1)
    nowTime = datetime.now()
    print ('Right now it's %s hours, %s minutes and %s seconds.' % (nowTime.hour,nowTime.minute,nowTime.second))
    time.sleep(5)

当这段代码尝试执行时，我收到以下错误：

Traceback (most recent call last):
  File "/Users/Teolicht/Desktop/Python/testy.py", line 219, in <module>
    start()
  File "/Users/Teolicht/Desktop/Python/testy.py", line 18, in start
    questions()
  File "/Users/Teolicht/Desktop/Python/testy.py", line 34, in questions
    day()
  File "/Users/Teolicht/Desktop/Python/testy.py", line 52, in day
    time()
TypeError: 'module' object is not callable

start()、questions() 和day() 是程序在通过time() 之前经过的一些其他功能。如果我尝试直接执行time()，它会起作用！所以，这是time()函数从开始到结束的整个代码：

from datetime import datetime
import time
import random
import sys

def start():
    import time
    name = input('Hi. What is your name? ')
    print ('Nice to meet you, ' + str(name) + '.')
    time.sleep(1)
    print ('How old are you?')
    age = input()
    time.sleep(1)
    print (age + '! Cool.')
    time.sleep(2)
    questions()

def questions():
    import time
    print ('Some things you can ask me:')
    time.sleep(1)
    print ('• What day is today? (qdh)')
    time.sleep(1)
    print ('• What time is it? (qhs)')
    time.sleep(1)
    print ('• I want to play a game! (qjj)')
    time.sleep(1)
    print ('• How many days till my birthday? (qda)')
    time.sleep(1)
    questionsAnswer = input()
    if questionsAnswer == 'qdh':
        day()
    elif questionsAnswer == 'qhs':
        time()
    elif questionsAnswer == 'qjj':
        game()
    else:
        birthday()

def day():
    import time
    time.sleep(1)
    nowDay = datetime.now()
    print ('Today is %s/%s/%s' % (nowDay.day,nowDay.month,nowDay.year))
    time.sleep(2)
    dayAnswer = input('Want to know what time it is? "Y" for yes and "N" for no: ').lower()
    if dayAnswer == 'n':
        questions()
    else:
        time()

def time():
    import time
    time.sleep(1)
    nowTime = datetime.now()
    print ('Right now it's %s hours, %s minutes and %s seconds.' % (nowTime.hour,nowTime.minute,nowTime.second))
    time.sleep(5)
        questions()
       ...

可能是 start()、questions() 或 day() 中的某些内容导致错误。有任何想法吗？非常感谢！

Answer 1

它对我有用，尽量不要创建自己的 time() 方法，我将它重命名为“my_time()”。

时间模块定义了很多函数，或者你只是“导入时间”，或者你需要指定你想要导入的每个函数，比如“从时间导入睡眠”

from datetime import datetime
from time import time, sleep
import random
import sys

def questions():
    print ('Some things you can ask me:')
    sleep(1)
    print ('• What day is today? (qdh)')
    sleep(1)
    print ('• What time is it? (qhs)')
    sleep(1)
    print ('• I want to play a game! (qjj)')
    sleep(1)
    print ('• How many days till my birthday? (qda)')
    sleep(1)
    questionsAnswer = input()
    if questionsAnswer == 'qdh':
        day()
    elif questionsAnswer == 'qhs':
        my_time()
    elif questionsAnswer == 'qjj':
        my_game()
    else:
        my_birthday()

def day():
    sleep(1)
    nowDay = datetime.now()
    print ('Today is %s/%s/%s' % (nowDay.day,nowDay.month,nowDay.year))
    sleep(2)
    dayAnswer = input('Want to know what time it is? "Y" for yes and "N" for no: ').lower()
    if dayAnswer == 'n':
        questions()
    else:
        my_time()

def my_time():
    sleep(1)
    nowTime = datetime.now()
    print ('Right now it\'s %s hours, %s minutes and %s seconds.' % (nowTime.hour, nowTime.minute, nowTime.second))
    sleep(5)
    questions()

def my_game():
    pass

def my_birthday():
    pass

#def start():
name = input('Hi. What is your name? ')
print ('Nice to meet you, ' + str(name) + '.')
sleep(1)
print ('How old are you?')
age = input()
sleep(1)
print (age + '! Cool.')
sleep(2)
questions()

Answer 2

在你的指挥下

nowTime = datetime.now()

datetime 是 module，它没有方法 now()。

你可能想要

nowTime = datetime.datetime.now()

其中第一个datetime 是module，第二个是其中的class - 使用类方法now() 创建具有当前本地日期和时间的object。

Answer 3

将您的 import time 替换为 from time import time。
