问题描述
大家好，
我有一本设置字典。 settinfgs可以是字符串，整数
或bools。我想将这个列表动态地写入磁盘中的一个很大的
for循环，不幸的是bool需要写入0或1到带有WriteInt的
配置，整数也用WriteInt和字符串
用简单的写。
列表是这样的;
options [A] = True
options [b] = 1
options [C] =" Hello"
I想使用isinstance来确定它是bool还是int或
字符串。但是我很困惑在交互式编辑器中尝试它;
.... print" OK"
....
OK
.... print" OK"
....
OK
我收不到。是以某种方式从''int'派生的bool？什么是
检查我想写的配置是int还是
bool的最好方法是什么？
问候，

... print" OK"
...
OK
...打印OK
...
OK
我不明白。是以某种方式从''int'派生的bool？
显然：是的！ - ）
False
False
但无论如何，我不明白这一点，因为需要写出bool
为0或1的配置与WriteInt，整数也与WriteInt。
所以你只是不在乎它是否是一个bool？或者我错过了什么？
...打印OK
...
OK>> if isinstance（a，int）：
...打印OK
...
好的

这是在过去两周的讨论中提出但我不能找到
找到它在搜索谷歌。
看来你可以得到确切的类（而不是这是
类或衍生物那个isinstance（）似乎提供了具有__class__属性的
：
True
False
True
False
Hi All,
I have a dictionary with settings. The settinfgs can be strings, ints
or bools. I would like to write this list dynamically to disk in a big
for loop, unfortunately the bools need to be written as 0 or 1 to the
config with WriteInt, the integers also with WriteInt and the strings
with a simple Write.
The list is something like;
options[A] = True
options[b] = 1
options[C] = "Hello"
I wanted to use isinstance to determine if it is a bool or an int or a
string. However I am confused trying it out in the interactive editor;
.... print "OK"
....
OK
.... print "OK"
....
OK
I don''t get it. is the bool derived from ''int'' in some way? What is
the best way to check if the config I want to write is an int or a
bool ?
Regards,

... print "OK"
...
OK
... print "OK"
...
OK
I don''t get it. is the bool derived from ''int'' in some way?
Obviously : yes !-)
False
False
But anyway, I don''t get the point, since "the bools need to be written
as 0 or 1 to the config with WriteInt, the integers also with WriteInt".
So you just don''t care if it''s a bool or not ? Or did I miss something ?
... print "OK"
...
OK>>if isinstance(a, int):
... print "OK"

This came up in a discussion within the last two weeks but I cannot
find it in a search of google.
It appear that you can get the exact class (as opposed to "is this
class or a derivative" that isinstance() seems to provide)
with the __class__ attribute:
True
False
True
False
