Python keyboard input

Question

I am beginner, how can I create a list of keys so that Presskey will randomly press a key from the list. I need a list of numpad keys, keyboard keys he[enter link description here http://web-old.archive.org/web/20190801085838/http://www.gamespp.com/directx/directInputKeyboardScanCodes.html

while (True):
    delay = random.uniform(0, 0.11)
    PressKey(0x4F)
    time.sleep(delay)
    ReleaseKey(0x4F)
    time.sleep(delay)

I got a simple solution for you using pyautogui module:

import pyautogui
import random
list_of_keys = ["num0", "num1", "num2", "num3", "num4", "num5", "num6", "num7", "num8", "num9"]
# or you can generate the keys using: ["num"+str(i) for i in range(10)]
key = random.choice(list_of_keys) # select random key from the list
pyautogui.press(key)

Basically I created list of numpad-keys (you can check out the pyautogui docs about key press here), selected random key from the list using random.choice(list) and pressed on the key using pyautogui.press(key).
Good Luck!
