      - pip install colorama
      - pip install package (requests)
- - - - file imports module - only access global attributes and functions
      - import multiple files at the same time: import a, b, c (should limited) -> instead that we will do:
        import a
        import b
        import c
      - when use import statement -> created one object with Module type
      - although "import" statements are called many times, but it only execute 1 time
      - can change value of attributes
      - reload module: from importlib import reload
    - - import more than one attribute, method ->
        import attributes, methods
      - import all attributes and method ->
        from a import * -> but suggestion
      - although "import" statements are called many times, but it only execute 1 time
      - can't change value of attributes (just copy) except object with list type
  - - - import folder.file
      - can import a package but shouldn't because can't access any module on that package, can do that through init.py file
    - - automatically run once package is imported
      - initialize variables at the same time
    - - use to import all modules of one package which are defined on init file
      - syntax: all = ['module_a',]
  - - - is a built-in variable which evaluates to the name of the current module
      - If the source file is executed as the main program, the interpreter sets the name variable to have a value “main”
      - name will be set to the module’s name
