在tkinter实验室显示实时控制台输出

Question

我想弄明白怎么做几天都没成功。 正如标题中提到的，有没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输出）？在

我有一个程序，可以读取一个.txt文件，并使用他的数据将一些坐标传递给一个正在我公司运行车队管理平台的云。在

感谢任何帮助！在

@edit:问题解决了 好吧，经过两天的努力，我终于找到了办法。首先，我把我的代码裁剪成函数，正如你在上面的代码中看到的，我只在一个函数中运行我的主逻辑，我把这个函数分成了更小的函数，如下所示。 为了显示使用标签的结果，我创建了一个函数，每次需要更新标签时都会调用该函数（def attLabel（）） 如果你试着运行上面的代码，你会发现当循环发生时GUI会冻结，为了解决这个问题，我使用线程库，在一个线程中运行我的逻辑，在另一个线程中运行GUI，这样我就可以在标签中显示活值了。 我知道我的代码不干净也不漂亮，但它做了他应该做的，所以。。。在

我找到的解决方案是： 创建线程以在mainloop（）之外运行函数 当我们在de mainloop（）线程中有任何类型的循环时，就会出现问题。 我用那个函数来解决我的问题

定义你自己的名字，我的名字是endTrue

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

变量来控制新线程内的循环

^{pr2}$

target=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

希望这对将来的人有帮助，gl和hf！在
