This article mainly explains "Python how to climb animation desktop high-definition wallpaper", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "Python how to climb animation desktop HD wallpaper" bar!

Preface

When designing a crawler project, you should first make clear in your mind the steps when manually browsing the page to get the picture.

Generally speaking, when we go to the Internet to open the wallpaper in bulk, the general operations are as follows:

1. Open the wallpaper web page

2. Click the wallpaper map (open the page that specifies the wallpaper)

3. Select the resolution (we want to download the high-definition picture)

4. Save the picture

In practice, we have realized the following steps to access the web address: open the wallpaper web page →, click the wallpaper image to open the specified page → resolution, click to open the final save target picture web page → to save the picture

In the process of the crawler, we try to simulate the operation of the browser to open the web page, obtain and visit the web page step by step, and finally get the download address of the target picture, download the picture and save it to the specified path.

* for the construction of some specific filter conditions of the web page in these intermediate processes, you need to open the source code of the specified page to observe and find the tags that contain the destination link.

Specific implementation projects and annotations

Here I just want to get some specified pictures, so I first searched for "Nagato Yuki" on the web page, opened a search results page, and found that this page already contained links to other wallpapers of the same type. so I started by setting the destination address of my initial visit to this search results page.

Screenshot of the target result page:

The subscript in the picture is "1gam29". "2gam29" is the wallpaper of other targets of the same type. by clicking on these pictures, we can open the new target download picture page.

Here let's take a look at the source code of the web page

The yellow bottom in the picture is the destination address of opening these similar wallpapers (access needs to be prefixed with "http://desk.zol.com.cn").

Now we can try to build a crawler:

Open the specified page → filter to get links to all the target download pages with hope wallpapers

The code is as follows:

After obtaining the address, we can open the specified page → to select the resolution → to obtain the destination download address → and save it to the local specified path by obtaining the address →.

During the test, I output the content saved in the previous step truelist.

You can see that what is saved is only a suffix, and we need to add a specified prefix when we visit.

The implementation code is as follows (see code for comments):

At this point, I believe that everyone on the "Python how to climb animation desktop high-definition wallpaper" have a deeper understanding, might as well to the actual operation of it!
