在函数期间更新 tkinter texvariable 标签

Question

我正在尝试制作一个控制发光测试机的程序。我正在使用 tkinter 对 GUI 进行编程，并且我制作了一个按钮来启动在机器上进行测试的功能。该函数在机器上启动 3 种不同的测试，并且在 GUI 中有一个框 (ttk.Label(root, textvariable=x)) 必须分别更新三个过程的结果。

当我按下按钮时，三个测试正确开始，当函数结束时，文本正确更新。但我想在函数运行期间更新它，以显示每次测试的结果，直到函数结束。

我一直在寻找和尝试，但我无法在函数运行期间而不是在函数结束时更新文本。

有人可以帮我吗？

这是我使用的函数的代码：

def inittest():
    if fn.initground()=='Y':
        progtext = ('Ground test has started')
        progress.set(progtext)
    elif fn.initground()=='N'
        progtext = ('Ground test has failed')
        progress.set(progtext)
    response = fn.receivedata()
    if len(response) == 1:
        progtext = (progtext + 'Data not received')
        progress.set(progtext)
    else:
        progtext = (progtext + response)
        progress.set(progtext)
    time.sleep(2)

    if fn.initisolate()=='Y':
        progtext = ('Isolate test has started')
        progress.set(progtext)
    elif fn.initisolate()=='N'
        progtext = ('Isolate test has failed')
        progress.set(progtext)
    response = fn.receivedata()
    if len(response) == 1:
        progtext = (progtext + 'Data not received')
        progress.set(progtext)
    else:
        progtext = (progtext + response)
        progress.set(progtext)
    time.sleep(2)

    if fn.initfun()=='Y':
        progtext = ('Function test has started')
        progress.set(progtext)
    elif fn.initfun()=='N'
        progtext = ('Function test has failed')
        progress.set(progtext)
    response = fn.receivedata()
    if len(response) == 1:
        progtext = (progtext + 'Data not received')
        progress.set(progtext)
    else:
        progtext = (progtext + response)
        progress.set(progtext)
    time.sleep(2)

好的，经过长时间的代码尝试，我终于得到了有效的代码。我在函数启动之前设置了一个全局值，并在每次测试完成后修改它。在此之后，我回忆起这个函数，它开始了第二次测试，因为我设置的全局值已经改变了。这是我使用的代码。感谢大家的帮助。

global action
action = 1

def inittest():

    global action

    if action == 1:
         def testground():
         global progtext
         if fn.initground()=='Y':
             progtext = ('Ground test has started')
             progress.set(progtext)
         elif fn.initground()=='N'
             progtext = ('Ground test has failed')
             progress.set(progtext)
         response = fn.receivedata()
         if len(response) == 1:
             progtext = (progtext + 'Data not received')
             progress.set(progtext)
         else:
             progtext = (progtext + response)
             progress.set(progtext)
         time.sleep(2)
     action = 2
     testground()
     root.after(1000, inittest)

     if action == 2:

         def testisolate():
         global progtext
         if initisolate()=='Y':
             progtext = (progtext + 'Isolate test has started')
             progress.set(progtext)
         elif fn.initisolate()=='N'
             progtext = (progtext + 'Isolate test has failed')
             progress.set(progtext)
         response = fn.receivedata()
         if len(response) == 1:
             progtext = (progtext + 'Data not received')
             progress.set(progtext)
         else:
             progtext = (progtext + response)
             progress.set(progtext)
         time.sleep(2)
     action = 3
     testisolate()
     root.after(1000, inittest)

     if action == 3:

         def testfun():
         global progtext
         if initfun()=='Y':
             progtext = (progtext + 'Function test has started')
             progress.set(progtext)
         elif fn.initfun()=='N'
             progtext = (progtext + 'Function test has failed')
             progress.set(progtext)
         response = fn.receivedata()
         if len(response) == 1:
             progtext = (progtext + 'Data not received')
             progress.set(progtext)
         else:
             progtext = (progtext + response)
             progress.set(progtext)
         time.sleep(2)
     action = 1
     testfun()
