**I made this to handle AZERY, QWERTY, and special characters on windows **
Take full control of your keyboard with this small Python library. Hook global events, register hotkeys, simulate key presses and much more.
- Global event hook on all keyboards (captures keys regardless of focus).
- Listen and send keyboard events.
- Works with Windows and Linux (requires sudo), with experimental OS X support (thanks @glitchassassin!).
- Pure Python, no C modules to be compiled.
- Zero dependencies. Trivial to install and deploy, just copy the files.
- Python 2 and 3.
- Complex hotkey support (e.g.
ctrl+shift+m, ctrl+space) with controllable timeout. - Includes high level API (e.g. record and play, add_abbreviation).
- Maps keys as they actually are in your layout, with full internationalization support (e.g.
Ctrl+ç). - Events automatically captured in separate thread, doesn't block main program.
- Tested and documented.
- Doesn't break accented dead keys (I'm looking at you, pyHook).
- Mouse support available via project mouse (
pip install mouse).
Install the PyPI package:
pip install keyboard
or clone the repository (no installation required, source files are sufficient):
git clone https://github.com/boppreh/keyboard
or download and extract the zip into your project folder.
Then check the API docs below to see what features are available.
Use as library:
import keyboard
keyboard.press_and_release('shift+s, space')
keyboard.write('The quick brown fox jumps over the lazy dog.')
keyboard.add_hotkey('ctrl+shift+a', print, args=('triggered', 'hotkey'))
# Press PAGE UP then PAGE DOWN to type "foobar".
keyboard.add_hotkey('page up, page down', lambda: keyboard.write('foobar'))
# Blocks until you press esc.
keyboard.wait('esc')
# Record events until 'esc' is pressed.
recorded = keyboard.record(until='esc')
# Then replay back at three times the speed.
keyboard.play(recorded, speed_factor=3)
# Type @@ then press space to replace with abbreviation.
keyboard.add_abbreviation('@@', '[email protected]')
# Block forever, like `while True`.
keyboard.wait()Use as standalone module:
# Save JSON events to a file until interrupted:
python -m keyboard > events.txt
cat events.txt
# {"event_type": "down", "scan_code": 25, "name": "p", "time": 1622447562.2994788, "is_keypad": false}
# {"event_type": "up", "scan_code": 25, "name": "p", "time": 1622447562.431007, "is_keypad": false}
# ...
# Replay events
python -m keyboard < events.txt- Events generated under Windows don't report device id (
event.device == None). #21 - Media keys on Linux may appear nameless (scan-code only) or not at all. #20
- Key suppression/blocking only available on Windows. #22
- To avoid depending on X, the Linux parts reads raw device files (
/dev/input/input*) but this requires root. - Other applications, such as some games, may register hooks that swallow all key events. In this case
keyboardwill be unable to report events. - This program makes no attempt to hide itself, so don't use it for keyloggers or online gaming bots. Be responsible.
- SSH connections forward only the text typed, not keyboard events. Therefore if you connect to a server or Raspberry PI that is running
keyboardvia SSH, the server will not detect your key events.

= 'down'= 'up'= {'alt', 'alt gr', 'ctrl', 'left alt', 'left ctrl', 'left shift', 'left windows', 'right alt', 'right ctrl', 'right shift', 'right windows', 'shift', 'windows'}= {'alt', 'ctrl', 'shift', 'windows'}= '0.13.5'Returns True if key is a scan code or name of a modifier key.
Returns a list of scan codes associated with this key (name or scan code).
Parses a user-provided hotkey into nested tuples representing the parsed structure, with the bottom values being lists of scan codes. Also accepts raw scan codes, which are then wrapped in the required number of nestings.
Example:
parse_hotkey("alt+shift+a, alt+b, c")
# Keys: ^~^ ^~~~^ ^ ^~^ ^ ^
# Steps: ^~~~~~~~~~^ ^~~~^ ^
# ((alt_codes, shift_codes, a_codes), (alt_codes, b_codes), (c_codes,))Sends OS events that perform the given hotkey hotkey.
hotkeycan be either a scan code (e.g. 57 for space), single key (e.g. 'space') or multi-key, multi-step hotkey (e.g. 'alt+F4, enter').do_pressif true then press events are sent. Defaults to True.do_releaseif true then release events are sent. Defaults to True.
send(57)
send('ctrl+alt+del')
send('alt+F4, enter')
send('shift+s')Note: keys are released in the opposite order they were pressed.
Presses and holds down a hotkey (see send).
Releases a hotkey (see send).
Returns True if the key is pressed.
is_pressed(57) #-> True
is_pressed('space') #-> True
is_pressed('ctrl+space') #-> TrueCalls the provided function in a new thread after waiting some time. Useful for giving the system some time to process an event, without blocking the current execution flow.
Installs a global listener on all available keyboards, invoking callback
each time a key is pressed or released.
The event passed to the callback is of type keyboard.KeyboardEvent,
with the following attributes:
name: an Unicode representation of the character (e.g. "&") or description (e.g. "space"). The name is always lower-case.scan_code: number representing the physical key, e.g. 55.time: timestamp of the time the event occurred, with as much precision as given by the OS.
Returns the given callback for easier development.
Invokes callback for every KEY_DOWN event. For details see hook.
Invokes callback for every KEY_UP event. For details see hook.
Hooks key up and key down events for a single key. Returns the event handler
created. To remove a hooked key use unhook_key(key) or
unhook_key(handler).
Note: this function shares state with hotkeys, so clear_all_hotkeys
affects it as well.
Invokes callback for KEY_DOWN event related to the given key. For details see hook.
Invokes callback for KEY_UP event related to the given key. For details see hook.
Removes a previously added hook, either by callback or by the return value
of hook.
Removes all keyboard hooks in use, including hotkeys, abbreviations, word
listeners, recorders and waits.
Suppresses all key events of the given key, regardless of modifiers.
Whenever the key src is pressed or released, regardless of modifiers,
press or release the hotkey dst instead.
Parses a user-provided hotkey. Differently from parse_hotkey,
instead of each step being a list of the different scan codes for each key,
each step is a list of all possible combinations of those scan codes.
Invokes a callback every time a hotkey is pressed. The hotkey must
be in the format ctrl+shift+a, s. This would trigger when the user holds
ctrl, shift and "a" at once, releases, and then presses "s". To represent
literal commas, pluses, and spaces, use their names ('comma', 'plus',
'space').
argsis an optional list of arguments to passed to the callback during each invocation.suppressdefines if successful triggers should block the keys from being sent to other programs.timeoutis the amount of seconds allowed to pass between key presses.trigger_on_releaseif true, the callback is invoked on key release instead of key press.
The event handler function is returned. To remove a hotkey call
remove_hotkey(hotkey) or remove_hotkey(handler).
before the hotkey state is reset.
Note: hotkeys are activated when the last key is pressed, not released.
Note: the callback is executed in a separate thread, asynchronously. For an
example of how to use a callback synchronously, see wait.
Examples:
# Different but equivalent ways to listen for a spacebar key press.
add_hotkey(' ', print, args=['space was pressed'])
add_hotkey('space', print, args=['space was pressed'])
add_hotkey('Space', print, args=['space was pressed'])
# Here 57 represents the keyboard code for spacebar; so you will be
# pressing 'spacebar', not '57' to activate the print function.
add_hotkey(57, print, args=['space was pressed'])
add_hotkey('ctrl+q', quit)
add_hotkey('ctrl+alt+enter, space', some_callback)Removes a previously hooked hotkey. Must be called with the value returned
by add_hotkey.
Removes all keyboard hotkeys in use, including abbreviations, word listeners,
recorders and waits.
Whenever the hotkey src is pressed, suppress it and send
dst instead.
Example:
remap('alt+w', 'ctrl+up')Builds a list of all currently pressed scan codes, releases them and returns
the list. Pairs well with restore_state and restore_modifiers.
Given a list of scan_codes ensures these keys, and only these keys, are
pressed. Pairs well with stash_state, alternative to restore_modifiers.
Like restore_state, but only restores modifier keys.
Sends artificial keyboard events to the OS, simulating the typing of a given text. Characters not available on the keyboard are typed as explicit unicode characters using OS-specific functionality, such as alt+codepoint.
To ensure text integrity, all currently pressed keys are released before the text is typed, and modifiers are restored afterwards.
delayis the number of seconds to wait between keypresses, defaults to no delay.restore_state_aftercan be used to restore the state of pressed keys after the text is typed, i.e. presses the keys that were released at the beginning. Defaults to True.exactforces typing all characters as explicit unicode (e.g. alt+codepoint or special events). If None, uses platform-specific suggested value.
Blocks the program execution until the given hotkey is pressed or, if given no parameters, blocks forever.
Returns a string representation of hotkey from the given key names, or the currently pressed keys if not given. This function:
- normalizes names;
- removes "left" and "right" prefixes;
- replaces the "+" key name with "plus" to avoid ambiguity;
- puts modifier keys first, in a standardized order;
- sort remaining keys;
- finally, joins everything with "+".
Example:
get_hotkey_name(['+', 'left ctrl', 'shift'])
# "ctrl+shift+plus"Blocks until a keyboard event happens, then returns that event.
Blocks until a keyboard event happens, then returns that event's name or, if missing, its scan code.
Similar to read_key(), but blocks until the user presses and releases a
hotkey (or single key), then returns a string representing the hotkey
pressed.
Example:
read_hotkey()
# "ctrl+shift+p"Given a sequence of events, tries to deduce what strings were typed.
Strings are separated when a non-textual key is pressed (such as tab or
enter). Characters are converted to uppercase according to shift and
capslock status. If allow_backspace is True, backspaces remove the last
character typed.
This function is a generator, so you can pass an infinite stream of events and convert them to strings in real time.
Note this functions is merely an heuristic. Windows for example keeps per- process keyboard state such as keyboard layout, and this information is not available for our hooks.
get_type_strings(record()) #-> ['This is what', 'I recorded', '']Starts recording all keyboard events into a global variable, or the given queue if any. Returns the queue of events and the hooked function.
Use stop_recording() or unhook(hooked_function) to stop.
Stops the global recording of events and returns a list of the events captured.
Records all keyboard events from all keyboards until the user presses the
given hotkey. Then returns the list of events recorded, of type
keyboard.KeyboardEvent. Pairs well with
play(events).
Note: this is a blocking function.
Note: for more details on the keyboard hook and events see hook.
Plays a sequence of recorded events, maintaining the relative time
intervals. If speed_factor is <= 0 then the actions are replayed as fast
as the OS allows. Pairs well with record().
Note: the current keyboard state is cleared at the beginning and restored at the end of the function.
Invokes a callback every time a sequence of characters is typed (e.g. 'pet') and followed by a trigger key (e.g. space). Modifiers (e.g. alt, ctrl, shift) are ignored.
wordthe typed text to be matched. E.g. 'pet'.callbackis an argument-less function to be invoked each time the word is typed.triggersis the list of keys that will cause a match to be checked. If the user presses some key that is not a character (len>1) and not in triggers, the characters so far will be discarded. By default the trigger is onlyspace.match_suffixdefines if endings of words should also be checked instead of only whole words. E.g. if true, typing 'carpet'+space will trigger the listener for 'pet'. Defaults to false, only whole words are checked.timeoutis the maximum number of seconds between typed characters before the current word is discarded. Defaults to 2 seconds.
Returns the event handler created. To remove a word listener use
remove_word_listener(word) or remove_word_listener(handler).
Note: all actions are performed on key down. Key up events are ignored. Note: word matches are case sensitive.
Removes a previously registered word listener. Accepts either the word used
during registration (exact string) or the event handler returned by the
add_word_listener or add_abbreviation functions.
Registers a hotkey that replaces one typed text with another. For example
add_abbreviation('tm', u'™')Replaces every "tm" followed by a space with a ™ symbol (and no space). The replacement is done by sending backspace events.
match_suffixdefines if endings of words should also be checked instead of only whole words. E.g. if true, typing 'carpet'+space will trigger the listener for 'pet'. Defaults to false, only whole words are checked.timeoutis the maximum number of seconds between typed characters before the current word is discarded. Defaults to 2 seconds.
For more details see add_word_listener.
Given a key name (e.g. "LEFT CONTROL"), clean up the string and convert to the canonical representation (e.g. "left ctrl") if one is known.
