Question

so that this way all I have to do is type

browser = MyBrowser()
browser.login()

to get my python scripts to log in in the future. Here’s what I have so far:

import mechanize
class MyBrowser(mechanize.Browser, object):
    _username = 'username'
    _password = 'password'

    def __init__(self):
        super(MyBrowser, self).__init__()
        self.set_handle_robots(False)
        self.set_proxies({"http" : "http://proxy.me.com:80"})

    def login(self):
        self.open('http://login.mypage.com/')
        self.select_form(nr=0)
        self['name'] = self._username
        self['pass'] = self._password
        self.submit()

I had made a login function that worked fine using this same methodology. But now, when I call browser.login(), I get this:

self['name'] = self._username
TypeError: 'MyBrowser' object does not support item assignment

Why doesn’t calling select_form behave the same way when it’s part of a method like this?

Answer 1

self is an object of the MyBrowser class.
What you have done with the self['name'] and self['pass'] is a try to assign values to the self object itself.

I assume you wanted to declare variables in the class, in order to do that you have to edit your code to:

self.name = self._username
self.pass = self._password

Edit:
Try this one:

super(MyBrowser, self).name = self._username
super(MyBrowser, self).password = self._password
