What does super() do?

Question

Hey guys,
at the moment I'm working with Python and PyQT and I found that some people are using the super() command. So my question is what does it do?

Class programm(QDialog):
def __init__(self):
super(programm, self).__init__() <----
loadUi('path', self)

Answer 1

With super() you invoke the class from which you inherit.

That can for example be useful when your derived class constructor takes more arguments than the base constructor.

You overwrite __init__ with the higher number of args, then from inside there you call super().__init__() with the number of args mommy class can handle. Like this you don't have to rewrite that code.

The additional args you treat manually after that.
