Create a simple task manager application using Python

In this article, we will explore how to use Python and Tkinter libraries to create a simple but powerful task manager application. This application will allow users to add, edit, delete and complete tasks and provide an intuitive user interface.

1. Design the user interface

We first designed the user interface. We will use the Tkinter library to create a basic GUI interface, including tags, text boxes, buttons and other components.

import tkinter as tk
from tkinter import ttk

# Create the main windowroot = ()
("task manager")

# Create a task list frameworktask_frame = (root, text="Task List")
task_frame.grid(row=0, column=0, padx=10, pady=5, sticky="nsew")

# Create a task listtask_list = (task_frame, height=15, width=50)
task_list.pack(fill="both", expand=True)

# Create scrollbarscrollbar = (task_frame, orient="vertical", command=task_list.yview)
(side="right", fill="y")

# Bind scrollbars and liststask_list.config(yscrollcommand=)

# Create a button framebutton_frame = (root, text="operate")
button_frame.grid(row=1, column=0, padx=10, pady=5, sticky="nsew")

# Create buttonadd_button = (button_frame, text="Add Task")
edit_button = (button_frame, text="Edit Task")
delete_button = (button_frame, text="Delete Task")
complete_button = (button_frame, text="Complete the task")

add_button.grid(row=0, column=0, padx=5, pady=3)
edit_button.grid(row=0, column=1, padx=5, pady=3)
delete_button.grid(row=0, column=2, padx=5, pady=3)
complete_button.grid(row=0, column=3, padx=5, pady=3)

# Start the main loop()

2. Implement functions

Now we will add functionality to the button and define some helper functions to handle the task list.

# Add a taskdef add_task():
    task = task_entry.get()
    if task:
        task_list.insert("end", task)
        task_entry.delete(0, "end")

# Edit Taskdef edit_task():
    selected_task = task_list.curselection()
    if selected_task:
        index = selected_task[0]
        task_entry.delete(0, "end")
        task_entry.insert("end", task_list.get(index))
        task_list.delete(index)

# Delete the taskdef delete_task():
    selected_task = task_list.curselection()
    if selected_task:
        index = selected_task[0]
        task_list.delete(index)

# Complete the taskdef complete_task():
    selected_task = task_list.curselection()
    if selected_task:
        index = selected_task[0]
        task_list.itemconfig(index, {"bg": "light gray"})

# Create a task input boxtask_entry = (task_frame, width=50)
task_entry.pack(pady=5)

#Binding button functionadd_button.config(command=add_task)
edit_button.config(command=edit_task)
delete_button.config(command=delete_task)
complete_button.config(command=complete_task)

3. Run the application

Now that we have finished coding the application, let's run it! Test the functionality of the application by adding, editing, deleting, and completing tasks.

4. Summary

We learned how to create a simple task manager application using Python and Tkinter libraries. Although this app is simple, it provides a good starting point where you can further expand it according to your needs, such as adding more features, beautifying the interface, etc. Python's simplicity and the ease of use of the Tkinter library make creating GUI applications very simple and fun.
