An example to show how to search data in mechanize

browser = Browser()

browser.set_handle_robots(False) #ignore the robots.txt

response = browser.open("https://www.google.com")

print response.code

get all forms from the website

import mechanize

br = mechanize.Browser()

br.set_handle_robots(False) #ignore the robots.txt

br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')] # Google demands a user-agent that isn't a robot

br.open("https://www.google.com")

<response_seek_wrapper at 0x1081a4248 whose wrapped object = <closeable_response at 0x10819def0 whose fp = <socket._fileobject object at 0x108148a50>>>

for f in br.forms():
    print f

<f GET https://www.google.com/search application/x-www-form-urlencoded
  <HiddenControl(hl=en) (readonly)>
  <HiddenControl(source=hp) (readonly)>
  <HiddenControl(biw=) (readonly)>
  <HiddenControl(bih=) (readonly)>
  <TextControl(q=)>
  <SubmitControl(btnG=Google Search) (readonly)>
  <SubmitControl(btnI=I'm Feeling Lucky) (readonly)>
  <HiddenControl(gbv=1) (readonly)>>

Select the search box and search for ‘foo’

By default ‘f’ would represent the name of the form. ‘q’ would be one of the inputs of the form whose name is set to ‘q’

br.select_form('f')

br.form['q'] = 'foo'

get the search results

br.submit()
