如何使用python中的循环创建多个类对象？ [英] How to create multiple class objects with a loop in python?

问题描述

假设您必须在python中创建10个类对象，并对它们执行一些操作，例如：

Suppose you have to create 10 class objects in python, and do something with them, like:

obj_1 = MyClass()
other_object.add(obj_1)
obj_2 = MyClass()
other_object.add(obj_2)
.
.
.
obj_10 = MyClass()
other_object.add(obj_10)

你使用一个循环，并为每个对象（如 obj_1 ）分配一个变量，使代码更短？

How would you do it with a loop, and assign a variable to each object (like obj_1), so that the code will be shorter? Each object should be accessible outside the loop

obj_1.do_sth()

推荐答案

这个问题每天都会出现在某些变体中。答案是：保留您的数据超出您的变量名称，并这是必须的博客帖子。

This question is asked every day in some variation. The answer is: keep your data out of your variable names, and this is the obligatory blog post.

在这种情况下，为什么不列出objs？

In this case, why not make a list of objs?

objs = [MyClass() for i in range(10)]
for obj in objs:
    other_object.add(obj)

objs[0].do_sth()
