Mechanize is a Python library that allows developers to automate web browsing activities. It can be used for tasks such as web scraping, form filling, and automated testing.

Features

Mechanize provides several features that make it an ideal choice for web automation:

• Browser state preservation: Mechanize can preserve browser state across requests, including cookies, headers, and cache.
• HTML parsing and tagging: Mechanize has built-in parsing and tagging capabilities, allowing for easy identification and manipulation of HTML elements.
• Automatic form filling: Mechanize can automatically fill out web forms, including handling file uploads and multi-part forms.

Installation

To install Mechanize, run the following command in your terminal:

pip install mechanize

Usage

Using Mechanize to automate web browsing is straightforward. Here's an example of filling out a login form:

import mechanize

login_url = "https://example.com/login"
username = "myusername"
password = "mypassword"

browser = mechanize.Browser()

browser.open(login_url)

browser.select_form(nr=0)
browser.form['username'] = username
browser.form['password'] = password

response = browser.submit()

print(response.read())

This code logs into a hypothetical website by opening the login page, filling out the form, and submitting it. The response returned by Mechanize can then be read and parsed as needed.
