WallE

A python web scraping project which automatically downloads a random wallpaper and sets it on your desktop depending upon a few inputs.

Project Description

I made this project in order to learn web scraping. I have used requests and beautiful soup 4 to scrap a webpage and download wallpapers from there. When you run the main.py, you have two choices - set any random wallpaper or choose a category and then set the random wallpaper from that category.

How to run this project?

• Open your terminal and enter python main.py, if you have only python=>3 installed, else use python3 main.py
• You will be asked for either entering 1 or 2.
• If you choose 1
  • The program will download a random wallpaper and set it as your destop wallpaper
• If you choose 2
  • You will be first asked to choose a category. Enter the index accordingly and WallE will set your desktop wallpaper.

What different files do?

Basically, i have broken my entire project into different modules. Let's go by them one by one:

• main.py The main python file which calls other functions from different modules. You just need to run this one and chill.

• urls.py

  • mainUrl: The main url of the website,as i have used the main url of the website again and again.
  • file_url: The file path where the wallpaper gets stored. By default, images gets stored in 'wallpapers' folder in the project's directory. You can change it by changing variable dirName. I have used os.system, because it will make WallE adjust file namings depending on the os you are using.

• Image_downloader.py Downloads the wallpaper using the given 'image url' and saves in dirName

• LastPageCalculator.py As i am using random wallpapers, so i am using random.randint() python function. As it needs an upper bound, i am using calcLastpage() which find the last page for the website.

• Categories.py It scraps the categories of wallpapers and returns the url of the chosen category's page.

• SetWallPaper.py It uses the gnome command gsettings set org.gnome.desktop.background picture-uri fileurl to set the wallpaper from the directory specified.

• GetWallpaper.py The heart of the project which uses 'image downloader', 'SetWallpaper' modules to parse the main pages, get the image links, select a random image, download it, save it, and finally set the wallpaper.
