Trouble understanding a line of code in PyQt

I am trying to learn PyQt on my own from rapid gui programming with python and qt and having trouble understanding the meaning/requirement of below line of code mentioned in one of the example in the book.

class Form(QDialog):

        def __init__(self,parent=None):
                super(Form,self).__init__(parent) # Trouble understanding here

So, my question is what is the need of super(Form,self).__init__(parent) or what purpose it is trying to full fill in this code.

Take a look at the documentation of super():

Return a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used by getattr() except that the type itself is skipped.

So basically this line of code:

super(Form,self).__init__(parent)

finds the "closest" set __init__() method in classes from which current class (Form) is inheriting and initiates self object using this method and passing parent as the first argument.
