[Tutor] The def command

[Ivan Van Laningham]

Hi All--


You asked this earlier, as "how do I use the __def__ command to create
an object."

Def is not a command.  It's a statement.  You use it to create function
objects.  Like this:

def myfunction(s):
        print s

Then you can call it like this:

if __name__ == "__main__":
        myfunction("Hello, world!")

You can also do things like this:

xx = myfunction

(note the absence of parentheses after the name of the function; parens
after an object mean it is callable, like a function.)

Then, you can do things like this:

xx("Goodbye, Cruel World!")

If you want to know about objects like classes, look at the docs at
www.python.org, or as the tutor list some more specific question.
