Today, I will talk to you about how to achieve a free music downloader in Python. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Text 1) ideas

Enter any singer on a music home page, such as Li XX.

Where does the music come from? -in the server of the website

How do I get music from the website? -initiate a web request to the website

Finally, use tkinter to make an interface download box.

2) Environment

The environment used in this paper is as follows: Python3, Pycharm,requests, tkinter module.

Module installation: if you have any questions about the pip install + module name environment, you can come to me directly. (installation package, video, activation code are all available)

3) Code demonstration

3.1 Open Review element F12

Find the header file address:

Headers = {'Referer':' https://y.qq.com/portal/search.html', 'User-Agent':' Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)''Chrome/77.0.3865.90 Safari/537.36'}

3.2 complete project attached

Create a window root = Tk () # 2. Window title root.title ('QQ Music') # 3. Window size and display position, with lowercase xroot.geometry ('550x400' 550 '230') in the middle # window display position # 4. Label control lable = Label (root, text=', please enter the singer or song you need to download:', font= ('Microsoft Yahi', 10)) lable.grid (row=0, column=0) # 5. Input control entry = Entry (root, font= ('Microsoft Yahei', 25)) entry.grid (row=0, column=1) # 6. List box control text = Listbox (root, font= ('Microsoft Yahei', 16), width=45, height=10) # # the number of columns across months of the columnspan component text.grid (row=1, columnspan=2) # 7. Button controls button = Button (root, text=' start downloading', width=10, font= ('Microsoft Yahue', 10), command=downlaod_song) button.grid (row=2, column=0, sticky=W) button1 = Button (root, text=' exit', width=10, font= ('Microsoft Yahue', 10), command=root.quit) button1.grid (row=2, column=1, sticky=E) # message loop, display window root.mainloop () 4) effect display

Take Li XX as an example to download the song:
