[英]datetime.date: TypeError: an integer is required. Why?
class Photo:
'Fields: size, pdate'
def __init__(self, size, pdate):
self.size = size
self.pdate = pdate
def create_photo_name_dict(pdel):
photo_dictionary = {}
for photo in pdel:
photo_dictionary[photo[0]] = Photo(photo[1],datetime.date(photo[2:]).isoformat())
return photo_dictionary
create_photo_name_dict([["DSC315.JPG",55,2011,11,13],["DSC316.JPG",53,2011,11,12]])
This produces TypeError: an integer is required
. 这将产生
TypeError: an integer is required
。 What is the problem? 问题是什么?
datetime.date
needs an integer as its parameters. datetime.date
需要一个整数作为其参数。 With photo[2:]
You are passing a slice, which is a list. 使用
photo[2:]
您正在传递一个切片,这是一个列表。 Hence the error. 因此,错误。
To solve this, unpack the list: 要解决此问题,请解压缩列表:
photo_dictionary[photo[0]] = Photo(photo[1],datetime.date(*photo[2:]).isoformat())
Here is an example: 这是一个例子:
>>> datetime.date([2010,8, 7])
Traceback (most recent call last):
File "<pyshell#71>", line 1, in <module>
datetime.date([2010,8, 7])
TypeError: an integer is required
>>> datetime.date(*[2010,8, 7])
datetime.date(2010, 8, 7)
photo_dictionary[photo[0]] = Photo(photo[1],datetime.date(photo[2:]).isoformat())
Here, you are getting string in photo[0]
.. you need to typecast it using int(photo[0])
. 在这里,您在
photo[0]
中得到字符串。.您需要使用int(photo[0])
进行类型转换。
Also Check whether you are getting photo[0]
int
in string
format 另请检查您是否正在以
string
格式获取photo[0]
int
photo_dictionary[int(photo[0])] = Photo(photo[1],datetime.date(photo[2:]).isoformat())
