我遇到了 Python 错误。请参阅下面的代码示例。我运行 event_timer.py 并收到以下错误消息。下面列出的两个文件都在同一个文件夹中。
Traceback (most recent call last):
File "E:\python\event_timer\event_timer.py", line 7, in
timer = EventTimer()
TypeError: 'module' object is not callable
What am I missing?
event_timer.py:
import EventTimer
timer = EventTimer()
timer.addStep("Preheat Oven", seconds = 10)
timer.addStep("Cook Pizza", seconds = 20)
timer.addStep("Done!")
timer.start()
事件定时器.py:
import time
class Timer:
event = 'Event'
steps = []
def __init__(self, event = None):
if event is not None:
self.event = event
def addStep(self, step, seconds = None, minutes = None, hours = None, days = None):
if seconds is not None:
unit = 'seconds'
amount = seconds
elif minutes is not None:
unit = 'minutes'
amount = minutes
elif hours is not None:
unit = 'hours'
amount = hours
elif days is not None:
unit = 'days'
amount = days
else:
print 'Invalid arguments'
return False
self.steps.append({'unit': unit, 'amount': amount})
return True
def __timeInSeconds(self, unit, amount):
if unit == 'seconds':
return amount
elif unit == 'minutes':
return amount * 60
elif unit == 'hours':
return amount * 60 * 60
elif unit == 'days':
return amount * 60 * 60 * 24
else:
print 'Invalid unit'
return False
def start(self):
if len(self.steps) == 0:
print 'No steps to complete'
return False
print "{0} has started.".format(self.event)
for step in self.steps:
print step.step
time.sleep(self.__timeInSeconds(step.unit, step.amount))
print "Completed"
print 'Event complete'
最佳答案
当你写作时
import EventTimer
您创建了一个新变量，EventTimer，指向一个模块——您刚刚编写的模块!该模块内部是一个类 Timer。所以要创建该类的实例，您可以
timer = EventTimer.Timer()
