- Web Scraping: Web scraping is a technique for extracting information from websites. It involves making HTTP requests to a website’s server, downloading the HTML content of the web page, and then parsing that HTML data to extract the information you’re interested in.
The goal of web scraping is to automate the process of extracting data from websites, so that you can obtain the data you need without having to manually visit each website and copy the information by hand.
Example: Here’s a simple example of web scraping with BeautifulSoup:
In this example, we use the requests library to make a GET request to a website. If the request is successful (i.e. the HTTP status code is 200), we parse the HTML content of the page using BeautifulSoup and then find all the links in the page by searching for <a> tags. Finally, we print the href attribute of each link.
- Working with APIs: An API (Application Programming Interface) is a set of rules that allows one software application to interact with another. When you work with APIs, you are typically making requests to a server and receiving responses in return. The responses are usually in the form of JSON or XML data, which you can then parse and use in your own applications.
APIs provide a convenient way to access data from a variety of sources, such as weather data, stock market data, or social media data. By using an API, you can obtain data from a remote server without having to visit the website itself.
Example : here’s an example of working with APIs:
In this example, we use the requests library to make a GET request to an API endpoint. If the request is successful (i.e. the HTTP status code is 200), we parse the JSON data using the json() method of the response object and then do something with the data (in this case, we simply print it).
