Python doesn't have a main method. It's files are scripts and not programs. It's just like a shell script- everything is run. Unlike Java where everything has to be in a method in a class, you can have actions performed at the module level in Python. What you'll find is a lot of "if __name__ == '__main__'" conditionals. The name of the script that is run is always __main__, so you can use this to only run certain commands when the script is run directly as opposed to be imported by another module. __init__ is the equivalent of a Java constructor. > > > Thanks for clearing it up.
