MechanicalSoup: A Python repository from alaawahab

Home page

https://mechanicalsoup.readthedocs.io/

Overview

A Python library for automating interaction with websites. MechanicalSoup automatically stores and sends cookies, follows redirects, and can follow links and submit forms. It doesn't do JavaScript.

MechanicalSoup was created by M Hickford, who was a fond user of the Mechanize library. Unfortunately, Mechanize was incompatible with Python 3 until 2019 and its development stalled for several years. MechanicalSoup provides a similar API, built on Python giants Requests (for HTTP sessions) and BeautifulSoup (for document navigation). Since 2017 it is a project actively maintained by a small team including @hemberger and @moy.

Installation

PyPy3 is also supported (and tested against).

Download and install the latest released version from PyPI:

pip install MechanicalSoup

Download and install the development version from GitHub:

pip install git+https://github.com/MechanicalSoup/MechanicalSoup

Installing from source (installs the version in the current working directory):

python setup.py install

(In all cases, add --user to the install command to install in the current user's home directory.)

Example

From examples/expl_qwant.py, code to get the results from a Qwant search:

"""Example usage of MechanicalSoup to get the results from the Qwant
search engine.
"""

import re
import mechanicalsoup
import html
import urllib.parse

# Connect to duckduckgo
browser = mechanicalsoup.StatefulBrowser(user_agent='MechanicalSoup')
browser.open("https://lite.qwant.com/")

# Fill-in the search form
browser.select_form('#search-form')
browser["q"] = "MechanicalSoup"
browser.submit_selected()

# Display the results
for link in browser.page.select('.result a'):
    # Qwant shows redirection links, not the actual URL, so extract
    # the actual URL from the redirect link:
    href = link.attrs['href']
    m = re.match(r"^/redirect/[^/]*/(.*)$", href)
    if m:
        href = urllib.parse.unquote(m.group(1))
    print(link.text, '->', href)
