Traceback (most recent call last):
  File "C:/Users/User/PycharmProjects/dictionary/RobobrowseErp.py", line 26,

    print(open.parsed)
AttributeError: 'NoneType' object has no attribute 'parsed'

here is my code.

from robobrowser import RoboBrowser
import requests

start = requests.session()

token = 'value_of_token'
token_1 = 'value_of_token_1 '

stuff = {

   '__VIEWSTATEGENERATOR': token,
   'btnLogIn': 'Login',
   '__VIEWSTATE': token_1,
   'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, 
like Gecko) Chrome/23.0.1271.64 Safari/537.11'
}

start.headers = stuff


browser = RoboBrowser(parser='lxml', session=start)
browser.open('http://erp.college_name.edu/')
sign_in = browser.get_form(id='some_value')
sign_in['tbUserName'].value = 'myId'
sign_in['tbPassword'].value = 'myPass'
open = browser.submit_form(sign_in)
print(open.parsed)

here is the source code.

 <form name="form1" method="post" action="Welcome_iie.aspx" id="some_value" class="bgLogin">  <div class="formWrap">
                    <div class="error"> <span id="lblDispMessage"></span></div>
                        <div class="group">
                            <input name="tbUserName" type="text" id="tbUserName"><span class="highlight"></span><span class="bar"></span>
                            <label>Username</label>

                        <div class="group">
                              <input name="tbPassword" type="password" id="tbPassword"><span class="highlight"></span><span class="bar"></span>
                            <label>Password</label>
                        </div>

                           <input type="submit" name="btnLogIn" value="Login" onclick="return validation();" id="btnLogIn" class="button buttonBlue used">

okay, so the reason i was getting an AttributeError because in simple language.. things are not being parsed from the object itself i.e. opens ,it is predefined that robobrowser is an automated browser, so every thing is being automated ,to whatever request or method or whatever code we write so we have to do,

print(browser.parsed)

instead of

print(opens.parsed)

thanks!
