我试图在没有成功的情况下弄清楚如何做到这一点。 在tittle中，是否有任何方法可以使用tkinter在某种文本框或标签中显示控制台输出（特别是下面代码中的打印件）？
我有一个程序，它读取.txt文件，并使用他的数据将一些坐标传递给云，该云正在我公司运行车队管理平台。
感谢任何帮助！

@edit：问题解决了 好的，经过两天的工作，我终于找到了怎么做。首先，我在函数中剪切了代码，正如您在上面的代码中看到的那样，我的主逻辑只在一个函数中运行，我将该函数划分为更小的函数，如下所示。 要使用标签显示结果，我创建了一个每次需要更新标签时调用的函数（def attLabel（）） 如果您尝试运行上面的代码，您将看到GUI在循环出现时冻结，使用Thread库修复此问题，在一个线程中运行我的逻辑而在另一个线程中运行我的GUI使我能够显示标签中的实时值。 我知道我的代码不干净而美丽，但它正在做他应该做的事情，所以......

答案 0 :(得分：0)
我找到的解决方案是： 创建线程以在mainloop（）之外运行您的函数 当我们在de mainloop（）线程中有任何类型的循环时，问题就会发生。 我使用该功能来解决我的问题
def endTrue():
global flag
send_process = Thread(target=begin)
send_process.start()
flag = False
global flag
send_process = Thread(target=begin)
send_process.start()
flag = False
希望这能帮助将来的某个人，gl和hf！
