MODULES

• any python script (*.py) can be used as a module
• global variables are in a module scope (accidental override prevention)
• global module variables can be accessed using moduleName.varName
• the command 'from moduleName import *' does not import names starting with the '_' letter (hiding)
• modules can be pre-compiled to bytecode
• dir() function used for reflection - lists names defined in a module
• separate inspect module for reflection of names
• modules can be explicitly reloaded - reload() function
