If you are familiar to C++ or a similar language, the concept of the this pointer might not be alien to you. self in this context is basically a reference to the class itself. Hence self.file is creating a class member and setting to the input from file.
As Gary pointed out, during initialization, only the latter parameter i.e. file is being passed to __init__ You can get a brief tutorial from http://docs.python.org/tut/node11.html about classes in python.
