Hi forum! i didnt know where to post in this forum, so well… i posted here.

Can anyone help me with a few questions on python?
Im studying with a book, but the book doesnt explain a few things… Since im a java programmer, im obviously trying to see the differences between the two languages and i know python can be procedural language too… Anyway, can anyone help me with this simple code?


class Application():

    #THis is the constructor?
    #Why it receives self?
    def __init__(self):
        print "__init__"

    #Why it receives self?
    def printText(self, text):
        print text


class Example():
    def run(self):
        print "Hello, world!"





a = Application()
#Why i dont need to pass, 'a" as a first parameter
a.printText("Hi World")


# i Dont get this :
if __name__ == '__main__':
    Example().run()
