# Built-in Python Interpreter

A python interpreter can be activated by pressing the keys CTRL + i in Windows and Linux and by using COMMAND + i in OS/X.

The `locals()` of the python interpreter are:

> - `cocos`

> - `director`

> - `self`

The interpreter also has some attributes that can be changed in runtime, like:

> - `opacity`

> - `color`

> - `cfg['code.font_size']`

> - `cfg['code.font_name']`

> - `cfg['code.font_color']`

For example:

    # 0 means, no opacity
    # 255 means,  full opacity
    self.opacity = 50

    # changing layer color to a reddish one
    self.color = (204, 32, 32 )

    # changing the font color to white
    self.cfg['code.font_color'] = (255,255,255)

    # changing the font size
    self.cfg['code.font_size'] = 24

    # changing the font name
    self.cfg['code.font_name'] = 'Courier New'

    # obtaining the current scene:
    current_scene = director.scene

Once the interpreter was activated, it will remain in memory. From now on, you can hide it and show it by pressing (again) the CTRL+i (or COMMAND+i) keys.
