pygame module to work with the keyboard
This module contains functions for dealing with the keyboard.
The event queue gets pygame.KEYDOWN and pygame.KEYUP events when the keyboard buttons are pressed and released. Both events have a key attribute that is a integer ID representing every key on the keyboard.
The pygame.KEYDOWN event has additional attributes unicode and scancode. unicode represents a single character string that is the fully translated character entered. This takes into account the shift and composition keys. scancode represents the platform-specific key code. This could be different from keyboard to keyboard, but is useful for key selection of weird keys like the multimedia keys.
There are many keyboard constants, they are used to represent keys on the keyboard. The following is a list of all keyboard constants:

The keyboard also has a list of modifier states that can be assembled by bitwise-ORing them together.
KMOD_NONE, KMOD_LSHIFT, KMOD_RSHIFT, KMOD_SHIFT, KMOD_CAPS, KMOD_LCTRL, KMOD_RCTRL, KMOD_CTRL, KMOD_LALT, KMOD_RALT, KMOD_ALT, KMOD_LMETA, KMOD_RMETA, KMOD_META, KMOD_NUM, KMOD_MODE
pygame.key.get_focused() -> booltrue if the display is receiving keyboard input from the system
This is true when the display window has keyboard focus from the system. If the display needs to ensure it does not lose keyboard focus, it can use pygame.event.set_grab() to grab all input.
pygame.key.get_pressed() -> boolsget the state of all keyboard buttons
Returns a sequence of boolean values representing the state of every key on the keyboard. Use the key constant values to index the array. A True value means the that button is pressed.
Getting the list of pushed buttons with this function is not the proper way to handle text entry from the user. You have no way to know the order of keys pressed, and rapidly pushed keys can be completely unnoticed between two calls to pygame.key.get_pressed(). There is also no way to translate these pushed keys into a fully translated character value. See the pygame.KEYDOWN events on the event queue for this functionality.
pygame.key.get_mods() -> intdetermine which modifier keys are being held
Returns a single integer representing a bitmask of all the modifier keys being held. Using bitwise operators you can test if specific shift keys are pressed, the state of the capslock button, and more.
pygame.key.set_mods(int) -> Nonetemporarily set which modifier keys are pressed
Create a bitmask of the modifier constants you want to impose on your program.
pygame.key.set_repeat() -> Nonepygame.key.set_repeat(delay, interval) -> Nonecontrol how held keys are repeated
When the keyboard repeat is enabled, keys that are held down will generate multiple pygame.KEYDOWN events. The delay is the number of milliseconds before the first repeated pygame.KEYDOWN will be sent. After that another pygame.KEYDOWN will be sent every interval milliseconds. If no arguments are passed the key repeat is disabled.
When pygame is initialized the key repeat is disabled.
pygame.key.get_repeat() -> (delay, interval)see how held keys are repeated
When the keyboard repeat is enabled, keys that are held down will generate multiple pygame.KEYDOWN events. The delay is the number of milliseconds before the first repeated pygame.KEYDOWN will be sent. After that another pygame.KEYDOWN will be sent every interval milliseconds.
When pygame is initialized the key repeat is disabled.
New in pygame 1.8.
pygame.key.name(key) -> stringget the name of a key identifier
Get the descriptive name of the button from a keyboard button id constant.
