When a module is first introduced by another program, its main program will run.

1. If you want a block in the module not to execute when the module is introduced, you can use the name attribute to make the block execute only when the module itself is running.

Note: there is a double underscore under * name* and * main*, and the space in the middle is removed in this way.
