今天用 Python＋Tkinter 做一個番茄鐘：專注 N 分鐘 → 休息 M 分鐘，支援開始／暫停／重置，完成會響鈴提醒。預設 25／5 分鐘，可自行調整。

功能重點

• 專注與休息時間可調整
• 開始、暫停、重置
• 每完成一輪會嗶一聲並自動切換
• 計數今天完成幾次番茄
• 按下 Enter 也能開始
• Tkinter 為標準庫（Windows、macOS 內建）。部分 Linux 需安裝 python3-tk。

程式碼（存成 pomodoro.py

python pomodoro.py

實作:

小提醒
想改成 50／10？介面上把「專注(分)」改 50、「休息(分)」改 10，按「重置」後再「開始」。
