如何解决Tkinter 说“不响应”，直到 webbrowser 关闭
Tkinter 说“不响应”，直到浏览器关闭 可以用多线程修复吗？ 我在这里添加了代码 beat() 有浏览器 我从solve()给他们打电话 按钮点击 我已经删除了一些代码，因为它说” 看起来您的帖子主要是代码；请添加更多详细信息。”
def solve():
if com.get() == "one":
d=e1.get()
if not len(d)==1:

else:

for z in range (1,len(a2.args)+1):

beat()

com=ttk.Combobox(root,width=12,textvariable=n)
com['values']=('one','two','three','four','five')
com.place(x=278,y=42)
root.mainloop()
问题是，如果我在另一个线程中调用beat()，问题仍然存在，可能是由于solve() includes beat()。忘记说这是使用sympy解决然后mathjax显示结果是webbrowser的chrome
解决方法
定义一个普通的 python 函数来执行 webbrowser 类似这样的事情：
from threading import Thread
def start_webbrowser(cwd):
webbrowser.get('"C:\Program Files\Google\Chrome\Application\chrome.exe" %s').open(cwd+'/'+'hmmmm.html')
webbrowser.close()
然后你可以使用：
webbrowser_thread = Thread(target=start_webbrowser,args=(cwd,),daemon=True)
webbrowser_thread.start()
这将启动一个新线程，其中 start_webbrowser 函数以 cwd 作为唯一参数被调用。有关 Python 线程的更多信息，请阅读 this
