Я использую selenium

 In [1]: import selenium  
In [2]: from selenium import webdriver   
In [3]: chrome = webdriver.Chrome()
  

Откройте официальный сайт python

 In [5]: chrome.get("http://www.python.org")
In [6]: chrome.title
Out[6]: 'Welcome to Python.org'
  

Методы извлечения

 In [11]: methods = [ m for m in dir(chrome) if not m.endswith("_")]
In [36]: len(methods)
Out[36]: 90
  

Тест getattr

 In [41]: getattr(chrome, methods[0])
Out[41]: <selenium.webdriver.remote.file_detector.LocalFileDetector at 0x7f436ebf7630>
In [42]: getattr(chrome, methods[1])
Out[42]: False
  

Это работает нормально, но когда доходит до его повторения

 In [43]: for m in methods:
    ...:     getattr(chrome, m)
    ...:

Я проверил, что в моем использовании цикла for или getattr нет ошибок.

В чем проблема с моими кодами?
