python-tkinter和glob.glob工作togheter

Question

Im new to tkinter and trying to open the explorer (on windows) so that i can chose what folder i want to use in my program. I found a template for tkinter and altered it to work with my function and how i need the filepath to be. Before i tried using tkinter to "select my folder", i had manually writen the directory in the glob.glob function like this glob.glob(r'C:\\Users\\Desktop\\Spyder\\*.log') (and it worked). So my new ide was to replace the pathname input from r'C:\\Users\\Desktop\\Spyder\\*.log' to a variabel that stored the same pathname but now it used tkinters askdirectory() to finde the directory inteed.

import glob
import os
from itertools import zip_longest
import tkinter as tk
from tkinter import filedialog

#-------------Connect to Access2013------------------ 
class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.pack()
        self.create_widgets()

    def create_widgets(self):

        self.select_folder = tk.Button(self)
        self.select_folder["text"] = "Open WindowsExplorer"
        self.select_folder["command"] = self.ask_directory_to_folder
        self.select_folder.pack(side="top")

        self.quit = tk.Button(self, text="QUIT", fg="red",
                              command=root.destroy)
        self.quit.pack(side="bottom")

    def ask_directory_to_folder(self):
        clerdatabase() # a funktion that resets the autonumber and deleats all data from every table
        print("Open!")
        filepath = filedialog.askdirectory()
        log_filepath = "r'"+ str(filepath +"/*.log'")
        right_log_filepath = log_filepath.replace('/','\ ').replace(' ','')
        find_filenames(right_log_filepath)

root = tk.Tk()
app = Application(master=root)
app.mainloop()

#--------------Scan selected folder for .log files and starts to scan files---------
def find_filenames(right_log_filepath): #finds every file in the chosen filepath

    print(right_log_filepath) # r'C:\Users\Desktop\Spyder\*.log'
    print("ok")
    filenames = [] # list for all the found filenames
    for filepath_search in glob.glob(str(right_log_filepath), recursive=True): #A for loop that opens every .log file in the chosen directory folder 
        print('run') 

My problem ist that i don´t get the for loop filepath_search to work (it prints "ok"). But the word run inside the for loop dose not print, i guess it´s because it gets stuck somewhere before that? Someone who has more experience with tkinter that can help me? Thanks

I guess issue caused by what is passed to glob.glob since it doesn't find anything. It seems that it is mostly related to the fact that you add ' characters at the beggining and end of your right_log_filepath.

In ask_directory_to_folder function replace:

log_filepath = "r'"+ str(filepath +"/*.log'")
right_log_filepath = log_filepath.replace('/','\ ').replace(' ','')
find_filenames(right_log_filepath)

With:

from os import path  # should be at the top of your file
log_filepath = path.join(filepath, "*.log")
find_filenames(log_filepath)
