Depending on your Python knowledge, and how much time you're allocating to learn this skill, it could take anywhere from two days to two years.
- Generally, it takes about one to six months to learn the fundamentals of Python, that means being able to work with variables, objects & data structures, flow control (conditions & loops), file I/O, functions, classes and basic web scraping tools such as requests library.
- After learning the fundamentals of Python, you can now move on to more advanced web scraping tools such as BeautifulSoup, Scrapy and Selenium. These technologies will not take very long to learn as they are easy to use, so you can cover their basics within a week by working on practical projects.
