[英]How to iterate over class attributes but not functions and returning the attribute values in python?
Building on this question looping over all member variables of a class in python基于这个问题,在 python 中循环一个类的所有成员变量
Regarding how to iterate over a class' attributes / non functions.关于如何迭代类的属性/非函数。 I want to loop over the class variable values and store in a list.
我想遍历类变量值并存储在列表中。
class Baz:
a = 'foo'
b = 'bar'
c = 'foobar'
d = 'fubar'
e = 'fubaz'
def __init__(self):
members = [attr for attr in dir(self) if not attr.startswith("__")]
print members
baz = Baz()
Will return ['a', 'b', 'c', 'd', 'e']
将返回
['a', 'b', 'c', 'd', 'e']
I would like the class attribute values in the list.我想要列表中的类属性值。
Use the getattr
function使用
getattr
函数
members = [getattr(self, attr) for attr in dir(self) if not attr.startswith("__")]
getattr(self, 'attr')
is equivalent of self.attr
getattr(self, 'attr')
相当于self.attr
Use the getattr method:使用getattr方法:
class Baz:
a = 'foo'
b = 'bar'
c = 'foobar'
d = 'fubar'
e = 'fubaz'
def __init__(self):
members = [getattr(self,attr) for attr in dir(self) if not attr.startswith("__")]
print members
baz = Baz()
['foo', 'bar', 'foobar', 'fubar', 'fubaz']
