Python implementation automatically monitors Github projects and opens web pages

Python implements automatic file categorization

The Python implementation helps you choose the double ball number

Preface:

Today we use a Python script to change “Bing image” to “desktop wallpaper” every day. Directly open the whole ~

Results show

Train of thought to sort out

1, through the web page, get the address of the picture

2, save the image to the absolute path

3, set the absolute path to the image as the wallpaper

4, batch wallpaper automatic switch

The modules needed are as follows:

import urllib.request
import requests
import os.path
import ctypes
Copy the code

First, get the address of the picture

This function gets the final IMG address of the image of the day, based on bing’s web page address, primarily through the requests module.

# request page, jump to the final IMG address
def get_img_url(raw_img_url="https://area.sinaapp.com/bingImg/") :
    r = requests.get(raw_img_url)
    img_url = r.url  # Get the url of the image file
    print('img_url:', img_url)
    return img_url
Copy the code

Second, save the image to local

This function saves the image to a directory of your choice and returns the absolute address of the current directory.

def save_img(img_url, dirname) :
    Save the image to the disk folder dirname
    try:
        if not os.path.exists(dirname):
            print('Folders', dirname, 'Nonexistent, re-established')
            # os.mkdir(dirname)
            os.makedirs(dirname)
        Get the file name of the image, including the suffix
        basename = "bing.jpg"
        Join the directory with the file name to get the image path
        filepath = os.path.join(dirname, basename)
        Download the image and save it in a folder
        urllib.request.urlretrieve(img_url, filepath)
    except IOError as e:
        print('File operation failed', e)
    except Exception as e:
        print(Error:, e)
    print("Save", filepath, "successfully!")

    return filepath
Copy the code

Third, set the absolute path to the image as the wallpaper

Set the image as desktop wallpaper using the absolute path of the image you obtained earlier.

def set_img_as_wallpaper(filepath) :
    ctypes.windll.user32.SystemParametersInfoW(20.0, filepath, 0)
Copy the code

Fourth, run the code’s main function

def main() :
    dirname = "D:\\bingImg"  # Location where the image is to be saved
    img_url = get_img_url()
    filepath = save_img(img_url, dirname)  # Path to the image file
    set_img_as_wallpaper(filepath)
Copy the code

How it works (at this point, you can go back to the top left image in the first image of this article)

Fifth, batch automatic replacement wallpaper

In this case, you can create a batch file named py_bingying. Bat in the same directory as the Python script.

@echo off
del g:\bingImg\*.jpg
python SetBingImgAsWallpaper.py
Copy the code

The second line deletes the bing images downloaded the day before before running the Python script, thus realizing the daily cleaning of old wallpaper and minimizing storage space. The third behavior is to run the Python script above.

How to achieve automatic wallpaper switch, here using the boot run above the batch process method.

Copy the batch file created above, go to the directory below, right-click – paste as a shortcut. In this way to achieve the boot start batch procedures, automatically clear and update wallpaper.

C: User/yourname/AppData/Roaming/Microsoft/Windows/Folder/Folder/Folder/Folder/Folder/Folder/Folder/Folder/Folder/Folder/Folder Set the batch program to run at a specified time each day.
