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!
