Hi Dick,

Ah.  Unwritten community knowledge.  *grin* Take a look at:


which explains that construct in detail.  Here's a three-sentence

When a Python program file is executed directly, a special variable called
'__name__' is set to the string "__main__".

The same program file, however, can be used as a module too, and on an
'import', the '__name__' ends up being something else.

So the 'if' statement above lets us do something different if the program
is being run directly, as opposed to being imported.

Hope this helps!
