我已經為此掙扎了幾個小時：import os, sys, reprint('Type the path to the folder.')input_path = input()input_path = os.path.join(input_path)print('Select the search term')input_term = input()search_regex = re.compile(input_term)all_files = os.listdir(input_path)for j in range(len(all_files)): new_path = os.path.join(input_path, all_files[j]) search_regex = re.compile(input_term) target_file = open(new_path, 'r') file_content = target_file.read() file_content_in_list = search_regex.findall(file_content) print('A grand total of ' + str(len(file_content_in_list)) + ' items were found at ' + str(new_path))這按預期工作。該代碼讀取給定文件夾中的所有文件，并檢查找到搜索詞的次數。但是，當我嘗試將代碼的不同部分定義為函數時，我只得到錯誤：import os, sys, redef select_folder(): print('Type the path to the folder.') input_path = input() input_path = os.path.join(input_path)def select_all_files(): all_files = os.listdir(input_path) for j in range(len(all_files)): search_a_file()def ask_for_regex(): print('Select the search term') input_term = input() search_regex = re.compile(input_term)def search_a_file(): new_path = os.path.join(input_path, all_files[j]) search_regex = re.compile(input_term) target_file = open(new_path, 'r') file_content = target_file.read() file_content_in_list = search_regex.findall(file_content) print('A grand total of ' + str(len(file_content_in_list)) + ' items were found at ' + str(new_path))select_folder(): #Syntax Error here! ask_for_regex(): select_all_files():# if i put them like this then everything break down. I guess the variables are forgotten?select_folder()ask_for_regex()select_all_files()我想這個錯誤是顯而易見的，但我無法理解它......
