Prerequisite: Python GUI – tkinter

In this article, we are going to write a script for background changing application using the py-wallpaper module in Python. The py-wallpaper module is used to change the background wallpaper.  Before starting we need to install py-wallpaper.

Installation:

To install this type the below command in the terminal.

pip install py-wallpaper

Getting Started

Import modules.

Python3




# import modules
from wallpaper import set_wallpaper, get_wallpaper

Now you can get your current background image location with get_wallpaper attributes and you can change with set_wallpaper.

Python3




# get current wallpaper's path
print(get_wallpaper())
 
# set your photo
set_wallpaper("location/to/image.jpg")

Output:

D:\img\wallpapersden.com_money-heist_3840x2232.jpg

Background changer Application with Tkinter: This Script implements the above Implementation into a GUI.

Python3




# import modules
from tkinter import *
from tkinter import filedialog
from wallpaper import set_wallpaper
 
# user define function
def change_wall():
   
    # set your photo
    try:
        set_wallpaper(str(path.get()))
        check = "success"
 
    except:
 
        check = "Wallpaper not found !"
    result.set(check)
 
 
def browseFiles():
    filename = filedialog.askopenfilename(initialdir="/",
                                          title="Select a File",
                                          filetypes=(("jpeg files", "*.jpg"), ("all files", "*.*")))
    path.set(filename)
     
    # Change label contents
    label_file_explorer.configure(text="File Opened: "+filename)
    return filename
 
 
# object of tkinter
# and background set for red
master = Tk()
master.configure(bg='light grey')
 
# Variable Classes in tkinter
result = StringVar()
path = StringVar()
 
 
label_file_explorer = Label(
    master, text="Select a image", width=100, fg="blue")
 
 
# Creating label for each information
# name using widget Label
Label(master, text="Select image : ", bg="light grey").grid(row=0, sticky=W)
Label(master, text="Status :", bg="light grey").grid(row=3, sticky=W)
 
 
# Creating label for class variable
# name using widget Entry
Label(master, text="", textvariable=result,
      bg="light grey").grid(row=3, column=1, sticky=W)
 
# creating a button using the widget
# Button that will call the submit function
b = Button(master, text="Open", command=browseFiles, bg="white")
b.grid(row=0, column=2, columnspan=2, rowspan=2, padx=5, pady=5,)
 
label_file_explorer.grid(column=1, row=1)
 
c = Button(master, text="Apply", command=change_wall, bg="white")
c.grid(row=2, column=2, columnspan=2, rowspan=2, padx=5, pady=5,)
 
mainloop()

Output:

After selecting this wallpaper.
