[BeckyEbook]

I tried something like this:

debug_file_name = "function_debug"
home = os.path.expanduser('~')
if os.path.isdir(os.path.join(home, 'Desktop\\Becky')):
    log_file_name = os.path.join(home, 'Desktop\\Becky', debug_file_name + '.log')
else:
    log_file_name = os.path.join(home, debug_file_name + '_' + '.log')

def log_message(message):
    print(message)
    with open(log_file_name, "a", encoding="utf-8") as f:
        f.write(message + "\n")
