  1. 4.1. Structure of a program
  2. ===========================
  3.  
  4. A Python program is constructed from code blocks. A *block* is a piece
  5. of Python program text that is executed as a unit. The following are
  6. blocks: a module, a function body, and a class definition. Each
  7. command typed interactively is a block.  A script file (a file given
  8. as standard input to the interpreter or specified as a command line
  9. argument to the interpreter) is a code block.  A script command (a
  10. command specified on the interpreter command line with the "-c"
  11. option) is a code block. A module run as a top level script (as module
  12. "__main__") from the command line using a "-m" argument is also a code
  13. block. The string argument passed to the built-in functions "eval()"
  14. and "exec()" is a code block.
  15.  
  16. A code block is executed in an *execution frame*.  A frame contains
  17. some administrative information (used for debugging) and determines
  18. where and how execution continues after the code block's execution has
  19. completed.
