x = SimpleClass()<\/code> creates the instance of class<\/a> (something like an object of this type).<\/p>\n

If you run it outside the loop, you have exactly one object and try to change it. simplelist.append(x)<\/code> in this case will append this unique object to list (and will change it each time) so you will have a list which contains many copies of one object.<\/p>\n

If you run it inside the loop, you have several various object instantiating one class. simplelist.append(x)<\/code> in this case will append each new object to list so you will have a list which contains many different objects.<\/p>\n

From the official Python docs:<\/p>\n

\n

Class instantiation uses function notation. Just pretend that the class object is a parameterless function that returns a new instance of the class. For example (assuming the above class):<\/p>\n

x = MyClass()<\/code><\/p>\n

creates a new instance of the class and assigns this object to the local variable x.<\/p>\n

The instantiation operation (\u201ccalling\u201d a class object) creates an empty object. Many classes like to create objects with instances customized to a specific initial state.<\/p>\n<\/blockquote><\/div>\n
