如何使用 Tkinter 和 Python 使用按钮命令连接小部件？

Question

This is my problem: I'm trying to create a GUI with Tkinter that can read multiple files in folders and show their values on the interface. But when I press the widget button nothing happens.

This is the script that I use, feel free to ask your questions if you don't understand my process.

I will be very thankful if someone can help me.

    for s in SOIList and valuesList:

        if s == selectedConfig.get() and s == selectedConfig.get():

           textfilespathB = 'C:/temp/dossiersoi2/'+s+'SOI.txt'
           textfilespathC = 'C:/temp/fichiervalues2/'+s+'val.txt'

           with open(textfilespathB, "r") as f:
               frame2 = Frame(root, width = 50, height = 100)
               frame2.grid(row = 2, column = 0)
               Label(frame2, text=f.read()).pack()

           with open(textfilespathC, "r") as f:
               frame4 = Frame(root, width = 50, height = 100)
               frame4.grid(row = 2, column = 1)
               Label(frame4, text=f.read()).pack()

        else:
            print("not working")

This is the GUI related to my script.

Consider this line of code:

for s in SOIList and valuesList:

It is not doing what you expect. From the comments to an earlier version of this answer it appears you want to iterate over SOIList and valuesList in parallel (ie: each time through the loop you want one item from one list and one item for the other).

The way to do that is explained nicely in the answers to this question: How to iterate through two lists in parallel?

In your case the code would look like this:

for s, v in zip(SOIList, valuesList):
    if s == selectedConfig.get() and v == selectedConfig.get():
        ...
