Python登录网页问题

Question

I am using Spyder to code my project in Python 3.6.

I've downloaded robobrowser to assist me in logging into a webpage since I am new to web-scraping and html.

I understand the process, but I'm having an issue when accessing form elements.

from robobrowser import RoboBrowser

browser = RoboBrowser(history=True)
url1 = "example_url"

username = "example_user"
password = "example_pass"

browser.open(url1)

form = browser.get_forms()
form['username'] = username

There appears to be only one form and when I tried an example converting it to a string, it appeared to be finding the form. For some reason it doesn't show up as a variable in the spyder workspace unless i convert to a string.

I looked at the html and the name as well as the id for the username entry is indeed 'username'. I get the error

form['username'] = username
       TypeError: list indices must be integers or slices, not str

It doesn't like me trying to access the index in form by 'username', however this is the syntax in all of the examples for this module that i've seen. (First answer to this link is what I'm using as a template https://www.quora.com/What-is-the-best-way-to-log-in-to-a-website-using-Python )

You may try using login and password directly in the url. Here is the scheme:

http://USERNAME:PASSWORD@example.com/
