在使用Tkinter时范围有问题，由于某种原因，当我打印"passw“时，它仍然是0，而不管是否输入了校验按钮。

您提供的代码根本不起作用，所以很难相信使用Tkinter的范围出现问题时，由于某种原因，当我打印"passw“时，它仍然是0，而不管是否输入了校验按钮，但是.我不想在这里进一步讨论了。

下面的代码与tkinter和Python 3一起工作，并执行您希望它做的事情。它仍然有点混乱，不会在使用Tkinter的Python版本上运行，除非您将tkinter更改为Tkinter，并做一些其他更改以使其在旧的系统上运行，但是.如果有必要，只需自己对代码进行小的调整，使其为您运行，并享受将输入到用户对话框小部件中的值打印到输出：

from tkinter import *
from tkinter import filedialog
import tkinter.ttk as ttk
# pwd = '/'
import os ; pwd = os.popen('pwd').read()

def  convert(filename, pdfFN):
    print('Converting', filename, 'to', pdfFN)    

def execute(): 
     passwYesNo = chckbttn_passw_value.get()    
     wmarkYesNo = chckbttn_wmark_value.get()
     user_entry = user_entry_value.get()     
     print(f'{passwYesNo=}, {wmarkYesNo=}, {user_entry=}')
      # pdf = Pdf.open(pdfFN, allow_overwriting_input=True)
