这个是让 ChatGPT 写的判断素数的代码，使用 Python 3.11.2 版本 执行，但是进度条不管怎么改都不完美。
之前 GUI 界面上没进度条的，命令行窗口里有，很准确，还有倒计时、百分比等信息，
移到 GUI 界面上就一直不完美，要么点了判断，进度条不走，出结果的时候一下子拉满；要么进度条走完了还在计算中，代码里用 progress_bar_max_time = 5 的固定值不咋地，弄个预估的动态值也行啊，ChatGPT 也知道我的意思，就是弄不出来。
我要求就是点判断后进度条开始匀速走，走完了刚好出来结果，最好进度条右边放个动态百分比数字。
放进度条就是为了计算大一点数时直观感受到大概时间
