![]() However, if the data is spread over a large number of links, the website is difficult to navigate (eg. For any small number of infrequently changing or accessed data sources it is perfectly fine to navigate to these links via one's browser and simply manually download the required information. To use the data located at these URLs it needs to be extracted from the remote site and then stored and staged in a local repository.ĭealing with this kind of extraction is simple enough when one is only managing a small number of external data sources. Frequently, this external data is hosted via websites and is accessible as a link or otherwise reachable through an API provided by an external endpoint at a specified URL. This external data may be the primary dataset or could be in some instances an additional secondary dataset to be combined with other internal data from surveys, applications or databases to improve the insights and accuracy of the model. When doing research, business intelligence or predictive modeling there is often a need to utilize data from external sources as input to the model being developed as a part of the analysis. ![]() Tinkerer, maker, hacker, teacher, writer, learner, failure.Data Scraping with Python in More than 4 Minutes ![]() Give it a try, see what you can do with it! Les Pounder Obviously I am not going to give you the code for that, if you want to do that then you will have to work it out for yourself! :) Go and have fun with it! If your intention is purely evil, then you could also use this library to open a really annoying web page based on the time of day. ![]() For example here is a quick demo code that opens BBC news when a button is pressed. Instead of moving a mouse to open a web page to check the news / weather / bitcoin price, we can simply use webbrowser to open the page when a button is pressed. This library could be really handy for those that create custom user interfaces for those with special needs. The websites are saved as a list, and then we use a for loop to iterate of the items in the list and use them as the URL that we wish to open. Lets write something in IDLE3 that will open many websites in separate tabs. It is already installed as standard! So how can I use it? Not as clean and easy as webbrowser which enables us to pass the website as an argument. import subprocessĪnd here is the same thing using webbrowser import webbrowserīoth are two lines of Python, but using subprocess we need to create a list that contains the command xdg-open at index 0 and then the parameters / argument that is the website is passed as a second item in the list. Sure you can, but using webbrowser we have a Pythonic way of calling the browser, rather than using Python to call bash / command line to run a command to open a browser there.įor arguments sake, here is how to open the default web browser on my Linux system using subprocess. Can't I just use subprocess / popen / something else? Webbrowser is a Pythonic way to open a web browser on any operating system. This week a handy Python library that enables us to open a web browser!
