如果我有这样的课程。
class Person():
def __init__(self, name):
self._name = name
self._name_list = []
if(self._name not in self._name_list):
self._name_list.append(self._name)
father = Person("Michael")
mother = Person("Sharon")
>>>self._name_list
["Michael", "Sharon"]
如何在不创建全局变量的情况下执行此操作?每次我实例化一个新人时,它都会创建自己的列表。但是我需要在每个创建新人时附加名称的类范围内的列表。

您可以将其保存在类本身中,如下所示:
var opt = {
url: 'https://tartan.plaid.com/connect',
form: {
// ...
}
};
request.post(opt, function (error, response, body) {
console.log(body)
});
输出:
class Person():
_name_list = []
def __init__(self, name):
self._name = name
if self._name not in self._name_list:
self._name_list.append(self._name)
father = Person("Michael")
mother = Person("Sharon")
print(Person._name_list)

你可以试试这个:
people = []
class Person():
def __init__(self, name):
self._name = name
if self._name not in people:
global people
people.append(self._name)
person = Person('name1')
person1 = Person('name2')
print(people)
输出:
['name1', 'name2']
