向课程添加列表? [英] Add lists to class?
问题描述
我有一个列表,其中包含一些字符串,''一个',''两个''''三'',所以
on。我想将列表添加到具有这些名称的类中。我没有
的方式知道列表中的内容或列表将在多长时间内提前
.
类似的东西:
班主:
def __init __(自我,列表):
self.count = len(list)
列表中的行:
self.line = []#显然这不起作用
list = [ ''one'',''two'',''three'']
a =主人(清单)
所以我得到:
dir(a)
[''_doc__'',''_ init__'',''_ module _'',' '一'',''两'',''三'']
而不是:
dir(a)
[''_doc__'',''_init__'',''_ module__'',''line'']
TIA,

感谢慷慨的Pyhtonista回复了指向setattr()的指针。

我想你想要的是这个(未经测试):
班主:
def __init __(self,list):
self.count = len(list)
列表中的条目:
self .__ dict__ [entry] = []
这将使你获得具有三个属性的大师级
a = master(list)
a.one
a.two
a.three
每个包含一个空列表。你可以做一些事情
喜欢:
a.one.append(某事物)
a.three.append(某物) )

类似于:

def __init __(自我,列表):
self.count = len(list)
列表中的行:
self.line = []#显然这不是'工作
list = [''one'',''two'',''three'']
a = master(list)
所以我得到:
dir(a)
[''_doc__'',''_init__'',''_ module _'',''一个'',''''',''三个'']
代替:
dir(a)
['' _doc__'',''_init__'',''_ _ module__'',''line'']

测试和工作......

I have a list with some strings in in it, ''one'', ''two'' ''three'' and so
on. I would like to add lists to a class with those names. I have no
way of knowing what will be in the list or how long the list will be in
advance.
Something like:
class master:
def __init__(self, list):
self.count = len(list)
for line in list:
self.line = [] # obviously this doesn''t work
list = [''one'', ''two'', ''three'']
a = master(list)
so that I get:
dir(a)
[''_doc__'', ''_init__'', ''_module__'', ''one'', ''two'', ''three'']
instead of:
dir(a)
[''_doc__'', ''_init__'', ''_module__'', ''line'']

Thanks to a generous Pyhtonista replied with a pointer to setattr().

I think what you want is this (not tested):
class master:
def __init__(self, list):
self.count = len(list)
for entry in list:
self.__dict__[entry]= []
This will get you master class with three attributes
a = master(list)
a.one
a.two
a.three
each containing an empty list. You can then do things
like:
a.one.append(something)
a.three.append(something)
