You can use python-form-parser

from lxml import etree
from urllib import urlencode

html_string = """
    <html>
        <body>
            <form action="my_path", method="POST" id="my_form">
                  <input type="text" name="my_field" value="my_value"/>
                  <input type="text" name="my_field2"/>
                  <input type="submit" name="my_submit" value="Submit the form"/>
            </form>
        </body>
    </html>
"""

# parse and extract the form
tree = etree.HTML(html_string)
form = tree.xpath("//form[@id='my_form']")[0]

# Extract default values and meta information
ff = FormFiller(form)

# click to 'my_submit' button: will return dictionary with all fields values
form_data = ff.click('my_submit')
print form_data
{"my_field": "my_value",
 "my_submit": "Submit the form"}

# fill user data
form_data['some_name'] = 'some_value'

# prefered way on how to fill user data:
print ff.fill('my_submit', my_field2="my_value2")
{"my_field": "my_value",
 "my_field2": "my_value2",
 "my_submit": "Submit the form"}

# fields that not present on the original form are not allowed
ff.fill('my_submit', field_not_present_in_form_name="my_value3")
KeyError: 'Invalid form field'

# prepare data for sending
body = urlencode(form_data)
url = ff.get_action_url("http://example.com/forms/my_form.html")
print url
'http://example.com/forms/my_path'  # my_path from form's "action" attribute
method = ff.get_method()
print method
'POST'  # from form's "method" attr (GET is default)
