commands by text list

I'm doing an artificial intelligence project I'm trying to get my boat to run command from a list in .txt but I'm running into next

  

errorFile "C: /Users/leandro/PycharmProjects/Iana/main.py", line 22, in   load_cmds       indexError: list index out of range

When I delete everything I have in this list, cmds.txt works but I can not see the commands because there are none in the list, please someone can help me

follow the code:

from chatterbot import ChatBot
# from datetime import datetime
import os

import speech_recognition as sr

import pyttsx3

speaker = pyttsx3.init('sapi5')

bot = ChatBot('Iana', read_only=True)

dict_cmds = {}


def load_cmds():
    lines = open('cmds.txt', 'r').readline()

    for line in lines:
        line = line.replace('\n', '')
        parts = line.split('\t')
        dict_cmds.update({parts[0]: parts[1]})


def Speak(text):
    speaker.say(text)
    speaker.runAndWait()


load_cmds()
for k, v in dict_cmds.items():
    print(k, '====>', v)

r = sr.Recognizer()

with sr.Microphone() as s:
    r.adjust_for_ambient_noise(s)
    print('voce: ')

    while True:
        audio = r.listen(s)
        speech = r.recognize_google(audio, language='pt')
        response = bot.get_response(speech)
        print('você disse ', speech)
        print('Ana:', response)
        Speak(response)
