Hi Fatwallet, May I have some of your money? Oh, sorry, the main function... The main function is *not* like that of Java, if Java is ike C in that execution starts in main(). In Python, you can create a function called main and it behaves just like any other function. Stick that function in a file and the python interpreter will create a function object out of it, assigned to the name main. Now, while directly interpreting a python file, the interpreter sets the global name __name__ to the value '__main__' If the file is being interpreted due to it being referenced via an import statement, then __name__ is set to the name of the module being imported. You can therefore use the value of the __name__ variable to get a file to do different things when imported versus when directly run. Some people arrange for a function called main to be called when directly interpreted; other don't. Its a convention only. Others use the trick to call test functions when directly executed, when the file is normally imported as a module. > and what is > __name__ > __main__ > > use for in terms of Java? > With respect, (hehe), maybe you need to indicate that you've searched the Python documentation on __name__ and __main__?
