This article to share with you is about Python how to download Baidu pictures in batches, Xiaobian feel quite practical, so share to everyone to learn, I hope you can gain something after reading this article, not much to say, follow Xiaobian to see it.

1. Get the url link of the picture

First, open the Baidu image home page, as shown in the following url index.

Next, switch the page to the traditional flip version, because it helps us crawl images! As shown below:

Comparing several urls found that pn parameter is the number of requests received. By modifying the pn parameter and observing the returned data, it is found that there can only be 60 images per page at most.

Note: gsm parameter is the hexadecimal expression of pn parameter, so it doesn't matter to remove it.

Then, right-click the source code and search objURL directly (ctrl+F).

So, we found the url we needed.

2. Save the image link locally.

Now, all we have to do is crawl that information out. The page has objURL, hoverURL…but we use objURL because this is the original image. So, how do I get objURL? Use regular expressions! So how do we do this with regular expressions? All it takes is one line of code.

II. Code demonstration

1. Get the image url code:

2. Save the image to the local code:

3. Main function code:
