Java main-class in python-syntax

this is an example Java Class with a main method.

public class MyMainClass{
    public static void main(){
        doThings();
    }
}

To start it i have to do a "javac" on it and then a "java" on its output.

I've been experimenting quite a bit with python lately, but i couldn't figure out how to structure my py-document to function exactly like a Java Class with main function. For example i tried to code Python like this:

class MyClass:
    def method(self):
        print("in main")

def main():
    mc = MyClass()
    mc.method()

if __name__ == "__main__":
    main()

But it doens't work. The output i get when starting the interpreter is:

   C:\Users\altug>python MyClass.py
   Traceback (mos开发者_Go百科t recent call last):
   File "MyClass.py", line 9, in <module>
   main()
   NameError: name 'main' is not defined

Something is wrong with its indentation or i admit even logical errors on my behalf. Can someone help me to code a Python-main-class that looks exactly like a Java class?

Why not...

class MyClass:
    def method(self):
        print("in main")

if __name__ == "__main__":
    MyClass().method()

That's the closest thing to Java that you'll get here.

It seems OK to me:

Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53)

>>> class MyClass:
...     def method(self):
...         print("in main")
... 
>>> def main():
...     mc = MyClass()
...     mc.method()
... 
>>> if __name__ == "__main__":
...     main()
... 
in main

What is the problem that you are experiencing?

Or, are you looking for something like the following?

Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53)

>>> class MyClass:
...     @staticmethod
...     def main():
...         print("in main")
... 
>>> if __name__ == "__main__":
...     MyClass.main()
... 
in main

The Python equivalent of your Java Class with a main method would be:

class MyClass:
    def main(self):
        print("in main")
        doThings()

You create an instance and call its method:

mc = MyClass()
mc.main()

I think the confusion is that you are using a main() function for your program, which isn't necessary, but is good practice. But your code seems fine.
