Question

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)

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?

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

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

Is this possible?

Answer 1

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)
