import re
import mechanize

br = mechanize.Browser()
br.open("http://www.example.com/")
follow second link with element text matching regular expression
response1 = br.follow_link(text_regex=r"cheese\s*shop", nr=1)
assert br.viewing_html()
print br.title()
print response1.geturl()
print response1.info()  # headers
print response1.read()  # body
br.select_form(name="order")
Browser passes through unknown attributes (including methods)
to the selected HTMLForm.
br["cheeses"] = ["mozzarella", "caerphilly"]  # (the method here is setitem)
Submit current form.  Browser calls .close() on the current response on
navigation, so this closes response1
response2 = br.submit()
print currently selected form (don't call .submit() on this, use br.submit())
print br.form
response3 = br.back()  # back to cheese shop (same data as response1)
the history mechanism returns cached response objects
we can still use the response, even though it was .close()d
response3.get_data()  # like .seek(0) followed by .read()
response4 = br.reload()  # fetches from server
for form in br.forms():
print form
.links() optionally accepts the keyword args of .follow_/.find_link()
for link in br.links(url_regex="python.org"):
print link
    br.follow_link(link)  # takes EITHER Link instance OR keyword args
    br.back()</pre>
