Use Python's requests third-party module to capture the King's glory to all the heroes ' skins

This article uses Python's third-party module requests to crawl the King to honor all the heroes ' pictures, and to save the pictures as a directory for each hero in the folder, convenient for use as a desktop wallpaper

The following specific code, which has passed the python3.6 test, can be run successfully:

For the Web connection you want to crawl can be found through the King's Honor official website,

Here is a sample folder to save the captured pictures:

The above is a simple example of capturing the glory of all heroes skin, the above code does not use Python multi-threading to perform the function of fetching pictures, so it may take a few minutes to execute,

Later in the improvement, add the use Python multithreading to perform the crawl task.

Use Python's requests third-party module to capture the King's glory to all the heroes ' skins
