python - tkinter .after() 秒和分

Question

嘿大家，我在 tkinter 中制作计时器时遇到问题，但我无法使用 time.sleep() 所以我使用 .after() 并且我遇到了新问题，我输入了一个条目，我希望条目编号为 * 60，并且在设定的时间之后，将写入一条文本，显示 >> 时间已结束! ，但是，60 应该如何表示换算成秒？我的代码:

from tkinter import * 
from playsound import playsound
from time import sleep
import time
def jik():
    a = int(text.get())
    app.after(a * 600)
    Label(app,text="time is over").pack()
app = Tk()
app.minsize(300,300)
app.maxsize(300,300)
text = Entry(app,font=20)
text.pack()
Button(app,text="start",command=jik).pack()
app.mainloop()

例如，如果我按数字 1，不到一秒就>>时间结束

Answer 1

after 命令以毫秒为单位接收输入，因此将其乘以 1000 将其转换为秒。

此外，我刚刚做了一个小例子，当时钟滴答作响时为您显示倒计时:

# Usually it is a good idea to refrain from importing everything from the tkinter
# package, as to not pollute your namespace
import tkinter as tk

root = tk.Tk()  # Customary to call your Tk object root
entry = tk.Entry(root)
entry.pack()

curtime = tk.Label(root)
curtime.pack()
is_running = False  # Global variable to ensure we can't run two timers at once


def countdown(count):
    global is_running
    if count > 0:
        curtime['text'] = f'{count:.2f}'  # Update label

        # Call the countdown function recursively until timer runs out
        root.after(50, countdown, count-0.05)  
    else:
        curtime['text'] = 'time is over'
        is_running = False


def btn_press():
    global is_running
    if is_running:
        return
    cnt = int(entry.get())
    is_running = True
    countdown(cnt)


tk.Button(root, text='start', command=btn_press).pack()
root.minsize(300, 300)
root.maxsize(300, 300)
root.mainloop()
