The code is: import os def dTask(): #Get a file name list file_list = os.listdir('C:\Users\B\Desktop\sil\sil2') #Change the extensions for file_name in file_list: entry_pos = 0; #Filter the file name first for '.' for position in range(0, len(file_name)): if file_name[position] == '.': break new_file_name = file_name[0
