[python] Key Presses in Python

Is it possible to make it appear to a system that a key was pressed, for example I need to make A key be pressed thousands of times, and it is much to time consuming to do it manually, I would like to write something to do it for me, and the only thing I know well enough is Python.

A better way to put it, I need to emulate a key press, I.E. not capture a key press.

More Info (as requested): I am running windows XP and need to send the keys to another application.

Check This module keyboard with many features.Install it, perhaps with this command:

pip3 install keyboard

Then Use this Code:

import keyboard
keyboard.write('A',delay=0)

If you Want to write 'A' multiple times, Then simply use a loop.
Note:
The key 'A' will be pressed for the whole windows.Means the script is running and you went to browser, the script will start writing there.

If you're platform is Windows, I wouldn't actually recommend Python. Instead, look into Autohotkey. Trust me, I love Python, but in this circumstance a macro program is the ideal tool for the job. Autohotkey's scripting is only decent (in my opinion), but the ease of simulating input will save you countless hours. Autohotkey scripts can be "compiled" as well so you don't need the interpreter to run the script.

Also, if this is for something on the Web, I recommend iMacros. It's a firefox plugin and therefore has a much better integration with websites. For example, you can say "write 1000 'a's in this form" instead of "simulate a mouseclick at (319,400) and then press 'a' 1000 times".

For Linux, I unfortunately have not been able to find a good way to easily create keyboard/mouse macros.

AutoHotKey is perfect for this kind of tasks (keyboard automation / remapping)

Script to send "A" 100 times:

Send {A 100}

That's all

EDIT: to send the keys to an specific application:

WinActivate Word
Send {A 100}

import keyboard

keyboard.press_and_release('anykey')

PyAutoGui also lets you press a button multiple times:

pyautogui.press('tab', presses=5)   # press TAB five times in a row

pyautogui.press('A', presses=1000)   # press A a thousand times in a row

Alternative way to set prefer window into foreground before send key press event.

hwnd = win32gui.FindWindowEx(0,0,0, "App title")
win32gui.SetForegroundWindow(hwnd)

You could also use PyAutoGui to send a virtual key presses.

Here's the documentation: https://pyautogui.readthedocs.org/en/latest/

import pyautogui


pyautogui.press('Any key combination')

You can also send keys like the shift key or enter key with:

import pyautogui

pyautogui.press('shift')

Pyautogui can also send straight text like so:

import pyautogui

pyautogui.typewrite('any text you want to type')

As for pressing the "A" key 1000 times, it would look something like this:

import pyautogui

for i in range(999):
    pyautogui.press("a")

alt-tab or other tasks that require more than one key to be pressed at the same time:

import pyautogui

# Holds down the alt key
pyautogui.keyDown("alt")

# Presses the tab key once
pyautogui.press("tab")

# Lets go of the alt key
pyautogui.keyUp("alt")

There's a solution:

import pyautogui
for i in range(1000):
    pyautogui.typewrite("a")
