其实就是一种简单的时间管理方法。具体来说，首先需要明确一个工作任务，设定好番茄时间（一般是 25 分钟），在这个时间内专注工作，中途不允许做任何与该任务无关的事，直到番茄钟响起，然后在纸上画一个记号，记录下来，然后设定休息时间（一般是五分钟）。

## ---------------------------- CONSTANTS -------------------------- #
PINK = "#e2979c"
RED = "#e7305b"
GREEN = "#9bdeac"
YELLOW = "#f7f5dd"
FONT_NAME = "Courier"
WORK_MIN = 25
SHORT_BREAK_MIN = 5
LONG_BREAK_MIN = 10
reps = 0
timer = None

## ---------------------------- TIMER RESET ------------------------ #
def reset_timer():
    window.after_cancel(timer)
    canvas.itemconfig(timer_text, text="00:00")
    title_label.config(text="Timer")
    check_marks.config(text="")

    start_button["state"] = "normal"

## ---------------------------- TIMER MECHANISM -------------------- #
def start_timer():
    global reps
    reps += 1

    work_sec = WORK_MIN * 60
    short_break_sec = SHORT_BREAK_MIN * 60
    long_break_sec = LONG_BREAK_MIN * 60

    if reps % 8 == 0:
        count_down(long_break_sec)
        title_label.config(text="Break", fg=RED)
    elif reps % 2 == 0:
        count_down(short_break_sec)
        title_label.config(text="Break", fg=PINK)
    else:
        count_down(work_sec)
        title_label.config(text="Work", fg=GREEN)

    start_button["state"] = "disabled"

## ---------------------------- COUNTDOWN MECHANISM ---------------- #
def count_down(count):
    count_min = math.floor(count / 60)
    count_sec = count % 60
    if count_sec < 10:
        count_sec = f"0{count_sec}"

    canvas.itemconfig(timer_text, text=f"{count_min}:{count_sec}")
    if count > 0:
        global timer
        timer = window.after(1000, count_down, count - 1)
    else:
        start_timer()
        marks = ""
        work_sessions = math.floor(reps / 2)
        for _ in range(work_sessions):
            marks += "✔"
        check_marks.config(text=marks)

## ---------------------------- UI SETUP --------------------------- #
window = Tk()
window.title("Pomodoro")
window.config(padx=100, pady=50, bg=YELLOW)

title_label = Label(text="Timer", fg=GREEN, bg=YELLOW, font=(FONT_NAME, 50))
title_label.grid(column=1, row=0)

canvas = Canvas(width=200, height=224, bg=YELLOW, highlightthickness=0)  # 高亮边框的宽度
tomato_img = PhotoImage(file="tomato.png")
canvas.create_image(100, 112, image=tomato_img)
timer_text = canvas.create_text(100, 130, text="00:00", fill="white", font=(FONT_NAME, 35, "bold"))
canvas.grid(column=1, row=1)

start_button = Button(text="Start", highlightthickness=0, command=start_timer)
start_button.grid(column=0, row=2)

reset_button = Button(text="Reset", highlightthickness=0, command=reset_timer)
reset_button.grid(column=2, row=2)

check_marks = Label(fg=GREEN, bg=YELLOW)
check_marks.grid(column=1, row=3)

window.mainloop()
