在tkinter标签中显示实时控制台输出

Question

我试图找出如何成功进行几天的尝试。 如标题所述，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内容）？

我有一个程序可以读取.txt文件，并使用他的数据将一些坐标传递给云，而云正在我公司中运行车队管理平台。

任何帮助表示赞赏！

@edit：问题解决了，好了，经过两天的努力，我终于找到了解决方法。 首先，我在函数中剪切了代码，如您在上面的代码中所看到的，我的主要逻辑只在一个函数中运行，我将该函数分成了一些较小的函数，如下所示。 为了显示我正在使用标签的结果，我创建了一个函数，每次我需要更新标签时都会调用该函数（def attLabel（））。如果您尝试运行上面的代码，您将看到循环时GUI冻结为了解决这个问题，我正在使用线程库，在一个线程中运行我的逻辑，在另一个线程中运行我的GUI，使我能够在标签中显示实时值。 我知道我的代码并不干净，漂亮，但是它正在做他应该做的事情，所以...

感谢您的帮助！

Answer 1

我发现的解决方案是：创建线程以在mainloop（）外部运行您的函数当在mainloop（）线程内部有任何类型的循环时，就会发生问题。 我用那个功能解决了我的问题

定义自己的名字，我的名字是endTrue

def endTrue():
    global flag
    send_process = Thread(target=begin)
    send_process.start()
    flag = False

变量以控制新线程内的循环

global flag

target =您要在侧线程中执行的函数

send_process = Thread(target=begin)

启动新线程

 send_process.start()

用于控制循环的变量

flag = False

希望这会在以后帮助某人，gl和hf！
