代码:
from tkinter import * from tkinter.ttk import * import time scale = 100 def running(): # 开始Progressbar动画 btn.configure(text="系统忙碌中...",state=DISABLED) print("\n"*2) print("执行开始".center(scale+28,'-')) start = time.perf_counter() for i in range(scale+1): pb["value"] = i # 每次更新1 root.update() # 更新画面 a = '*' * i b = '.' * (scale - i) c = (i/scale)*100 t = time.perf_counter() - start print("\r任务进度:{:>3.0f}% [{}->{}]消耗时间:{:.2f}s".format(c,a,b,t),end="") time.sleep(0.03) print("\n"+"执行结束".center(scale+28,'-')) btn.configure(text="重启任务",state=NORMAL) root = Tk() root.geometry("300x140+600+300") root.title("任务进度可视化") # 使用默认设置创建进度条 pb = Progressbar(root,length=200,mode="determinate",orient=HORIZONTAL) pb.pack(padx=10,pady=20) pb["maximum"] = 100 pb["value"] = 0 btn = Button(root,text="启动任务",command=running) btn.pack(pady=10) root.mainloop()运行效果截图:
