Python-创建多个对象的巧妙方法? [英] Python - neat way of creating multiple objects?

问题描述

我对Python还是很陌生，我对创建具有不同属性的多个对象的巧妙方法有疑问.目前，我必须像这样专门创建每个人:

I'm fairly new to Python and I have a question about a neat way of creating multiple objects with different properties. At the moment I am having to specifically create each one like this:

object1 = MyClass(property=foo,property2=bar)
object1.DoStuff(variable = foobar)

object2 = MyClass(property=foo,property2=bar2)
object2.DoStuff(variable = foobar)

object3 = MyClass(property=foo,property2=bar3)
object3.DoStuff(variable = foobar)

我的问题是我想以这种方式创建许多对象，并且不得不像这样手动创建每个对象，这似乎是非常糟糕的编程.有没有更好的方法来创建多个属性稍有不同的对象?

My problem is that I want to create dozens of objects in this way and having to manually create each one like this seems like very bad programming. Is there a better way to create multiple objects with slightly different properties?

我想我想要要做的事情是这样的:

I guess what I want to do is something like:

list = [prop1, prop2, prop3, prop4, prop5]
while i < len(list)
    object_i = MyClass(property=foo,property2=list[i])
    object_i.DoStuff(variable = foobar)
    i+=1

并创建5个名为object_1，object_2等的对象

And have this create 5 objects named object_1, object_2, etc etc

这可能吗?

推荐答案

如果您有名称为object_1，object_2等的对象，并且希望对所有这些对象执行通用操作，则这清楚地表明您实际上应该使用列表objects，并使用循环执行常见操作.

If you have objects with the names object_1, object_2 etc. and want to perform common operations on all these objects, this is a clear sign that you should actually be using a list objects, and use loops to perform the common operations.

props = <some list here>
objects = [MyClass(property=foo, property2=prop) for prop in props]
for obj in objects:
    obj.do_stuff(variable=foobar)
