问题描述

这是我的交易类:

  ):
def __init __(self,company,num,price,date,is_buy):
self.company = company
self.num = num
self.price = price
self.date = datetime.strptime(date,%Y-%m-%d)
self.is_buy = is_buy

当我试图运行 date 函数时:

  tr = Transaction('AAPL',600,'2013-10-25')
print tr.date
pre>

我收到以下错误:

  date = datetime.strptime(self.d,%Y-%m-%d)
AttributeError:'module'对象没有属性'strptime'
pre>

如何解决?

解决方案

你猜到了:

  import datetime 

。这意味着您必须这样做:

  datetime.datetime.strptime(date,%Y-%m-%d )

以访问 strptime 方法。或者,您可以将import语句更改为:

 来自datetime import datetime 



并且按原样存取。



datetime 模块也命名为class datetime

  #module类方法
datetime.datetime.strptime(date,%Y-%m-%d)


Here is my Transaction class:

class Transaction(object):
    def __init__(self, company, num, price, date, is_buy):
        self.company = company
        self.num = num
        self.price = price
        self.date = datetime.strptime(date, "%Y-%m-%d")
        self.is_buy = is_buy

And when I'm trying to run the date function:

tr = Transaction('AAPL', 600, '2013-10-25')
print tr.date

I'm getting the following error:

   self.date = datetime.strptime(self.d, "%Y-%m-%d")
 AttributeError: 'module' object has no attribute 'strptime'

How can I fix that?

解决方案

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")
