退屈なことはPythonにやらせよう ―ノンプログラマーにもできる自動化処理プログラミング (Al Sweigart(著)、相川 愛三(翻訳)、オライリージャパン)の第Ⅱ部(処理の自動化)、18章(GUIオートメーションによるキーボードとマウスの制御)、18.13(演習プロジェクト)、18.13.1(忙しそうに見せる)の解答を求めてみる。

コード

#!/usr/bin/env python3
import time
import pyautogui

x = 1
# secs = 10
secs = 1
while True:
    time.sleep(secs)
    pyautogui.moveRel(x, 0)
    x *= -1
    print(pyautogui.position())

入出力結果(Zsh、PowerShell、Terminal、Jupyter(IPython))
