This module contains functions for dealing with the keyboard.

The pygame.eventpygame module for interacting with events and queues queue gets pygame.KEYDOWN and pygame.KEYUP events when the keyboard buttons are pressed and released. Both events have key and mod attributes.

• key: an integer ID representing every key on the keyboard

• mod: a bitmask of all the modifier keys that were in a pressed state when the event occurred

The pygame.KEYDOWN event has the additional attributes unicode and scancode.

• unicode: a single character string that is the fully translated character entered, this takes into account the shift and composition keys

• scancode: the platform-specific key code, which could be different from keyboard to keyboard, but is useful for key selection of weird keys like the multimedia keys

New in pygame 2.0.0: The pygame.TEXTINPUT event is preferred to the unicode attribute of pygame.KEYDOWN. The attribute text contains the input.

The following is a list of all the constants (from pygame.localspygame constants) used to represent keyboard keys.

Portability note: The integers for key constants differ between pygame 1 and 2. Always use key constants (K_a) rather than integers directly (97) so that your key handling code works well on both pygame 1 and pygame 2.

The keyboard also has a list of modifier states (from pygame.localspygame constants) that can be assembled by bitwise-ORing them together.

pygame
Constant      Description
-------------------------
KMOD_NONE     no modifier keys pressed
KMOD_LSHIFT   left shift
KMOD_RSHIFT   right shift
KMOD_SHIFT    left shift or right shift or both
KMOD_LCTRL    left control
KMOD_RCTRL    right control
KMOD_CTRL     left control or right control or both
KMOD_LALT     left alt
KMOD_RALT     right alt
KMOD_ALT      left alt or right alt or both
KMOD_LMETA    left meta
KMOD_RMETA    right meta
KMOD_META     left meta or right meta or both
KMOD_CAPS     caps lock
KMOD_NUM      num lock
KMOD_MODE     AltGr

The modifier information is contained in the mod attribute of the pygame.KEYDOWN and pygame.KEYUP events. The mod attribute is a bitmask of all the modifier keys that were in a pressed state when the event occurred. The modifier information can be decoded using a bitwise AND (except for KMOD_NONE, which should be compared using equals ==). For example:

for event in pygame.event.get():
    if event.type == pygame.KEYDOWN or event.type == pygame.KEYUP:
        if event.mod == pygame.KMOD_NONE:
            print('No modifier keys were in a pressed state when this '
                  'event occurred.')
        else:
            if event.mod & pygame.KMOD_LSHIFT:
                print('Left shift was in a pressed state when this event '
                      'occurred.')
            if event.mod & pygame.KMOD_RSHIFT:
                print('Right shift was in a pressed state when this event '
                      'occurred.')
            if event.mod & pygame.KMOD_SHIFT:
                print('Left shift or right shift or both were in a '
                      'pressed state when this event occurred.')

pygame.key.get_focused()

true if the display is receiving keyboard input from the system

get_focused() -> bool

Returns 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()control the sharing of input devices with other applications to grab all input.

pygame.key.get_pressed()

get the state of all keyboard buttons

get_pressed() -> bools

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 that the button is pressed.

Note

Getting the list of pushed buttons with this function is not the proper way to handle text entry from the user. There is 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 pygame.eventpygame module for interacting with events and queues queue for this functionality.

pygame.key.get_mods()

determine which modifier keys are being held

get_mods() -> int

Returns a single integer representing a bitmask of all the modifier keys being held. Using bitwise operators you can test if specific modifier keys are pressed.

pygame.key.set_mods()

temporarily set which modifier keys are pressed

set_mods(int) -> None

Create a bitmask of the modifier key constants you want to impose on your program.

pygame.key.set_repeat()

control how held keys are repeated

set_repeat() -> None

set_repeat(delay) -> None

set_repeat(delay, interval) -> None

When the keyboard repeat is enabled, keys that are held down will generate multiple pygame.KEYDOWN events. The delay parameter is the number of milliseconds before the first repeated pygame.KEYDOWN event will be sent. After that, another pygame.KEYDOWN event will be sent every interval milliseconds. If a delay value is provided and an interval value is not provided or is 0, then the interval will be set to the same value as delay.

To disable key repeat call this function with no arguments or with delay set to 0.

When pygame is initialized the key repeat is disabled.

Raises

ValueError -- if delay or interval is < 0

Changed in pygame 2.0.0: A ValueError is now raised (instead of a pygame.error) if delay or interval is < 0.

pygame.key.get_repeat()

see how held keys are repeated

get_repeat() -> (delay, interval)

Get the delay and interval keyboard repeat values. Refer to pygame.key.set_repeat()control how held keys are repeated for a description of these values.

New in pygame 1.8.

pygame.key.name()

get the name of a key identifier

name(key) -> string

Get the descriptive name of the button from a keyboard button id constant.

pygame.key.key_code()

get the key identifier from a key name

key_code(name=string) -> int

Get the key identifier code from the descriptive name of the key. This returns an integer matching one of the K_* keycodes. For example:

>>> pygame.key.key_code("return") == pygame.K_RETURN
True
>>> pygame.key.key_code("0") == pygame.K_0
True
>>> pygame.key.key_code("space") == pygame.K_SPACE
True

Raises

• ValueError -- if the key name is not known.

• NotImplementedError -- if used with SDL 1.

New in pygame 2.0.0.

pygame.key.start_text_input()

start handling Unicode text input events

start_text_input() -> None

Start receiving pygame.TEXTEDITING and pygame.TEXTINPUT events. If applicable, show the on-screen keyboard or IME editor.

For many languages, key presses will automatically generate a corresponding pygame.TEXTINPUT event. Special keys like escape or function keys, and certain key combinations will not generate pygame.TEXTINPUT events.

In other languages, entering a single symbol may require multiple key presses, or a language-specific user interface. In this case, pygame.TEXTINPUT events are preferable to pygame.KEYDOWN events for text input.

A pygame.TEXTEDITING event is received when an IME composition is started or changed. It contains the composition text, length, and editing start position within the composition (attributes text, length, and start, respectively). When the composition is committed (or non-IME input is received), a pygame.TEXTINPUT event is generated.

Text input events handling is on by default.

New in pygame 2.0.0.

pygame.key.stop_text_input()

stop handling Unicode text input events

stop_text_input() -> None

Stop receiving pygame.TEXTEDITING and pygame.TEXTINPUT events. If an on-screen keyboard or IME editor was shown with pygame.key.start_text_input(), hide it again.

Text input events handling is on by default.

To avoid triggering the IME editor or the on-screen keyboard when the user is holding down a key during gameplay, text input should be disabled once text entry is finished, or when the user clicks outside of a text box.

New in pygame 2.0.0.

pygame.key.set_text_input_rect()

controls the position of the candidate list

set_text_input_rect(Rect) -> None

This sets the rectangle used for typing with an IME. It controls where the candidate list will open, if supported.

New in pygame 2.0.0.
