Python Tkinter Todo List

In this PythonTkinter tutorial, we will learn about how to create a Todo list in Python which help us to store our important ideas and daily task.

Python Tkinter Todo List

We create a Python Tkinter Todo List we have an interface with an entry box where we can enter the task and also have a button from which we can save our task.

Block of code:

In the following Python Tkinter Todo list block of code, we import some Tkinter modules from which we can create a Todo List.

from tkinter import *
import tkinter
import random
from tkinter import messagebox

Block of code:

In the following Python Tkinter Todo List block of code, we will define an update task function in which we can update our task.

• clearlistbox() is used to clear the list box.
• lbltask.insert(“end”, utask) is used to insert the task inside the entry box.
• numtask = len(tasks) is used to describe the length of the task.

def updatetask():
    clearlistbox()
    for utask in tasks:
        lbltask.insert("end", utask)
    numtask = len(tasks)
    lbldsp_count['text'] = numtask

Block of code:

In the following block of code, we define a clear list box function in which the task is deleted from the list.

def clearlistbox():
    lbltask.delete(0, "end")

Block of code:

In the following block of code, we define the add task function from which we can add our important information to the list.

def addtask():
    lbldisplay["text"] = ""
    Ntask = txtinput.get()
    if Ntask != "":
        tasks.append(Ntask)
        updatetask()
    else:
        lbldisplay["text"] = "please enter the text"
    txtinput.delete(0, 'end')

Block of code:

In the following block of code, we create a delete all function in which we can delete all the information that we can enter into the list. And also create a delete one function in which we can delete only one information that we are entered.

def deleteall():
    conf = messagebox.askquestion(
        'delet all??', 'are you sure to delete all task?')
    print(conf)
    if conf.upper() == "YES":
        global tasks
        tasks = []
        updatetask()
    else:
        pass


def deleteone():
    delt = lbltask.get("active")
    if delt in tasks:
        tasks.remove(delt)
    updatetask()

Block of code:

In the following block of code, we create some functions in which we can sort our task in ascending and descending order. And also generate the number of tasks.

def sortasc():
    tasks.sort()
    updatetask()


def sortdsc():
    tasks.sort(reverse=True)
    updatetask()


def randomtsk():
    randtask = random.choice(tasks)
    lbldisplay["text"] = randtask


def numbertsk():
    numtask = len(tasks)
    lbldisplay["text"] = numtask

Block of code:

In the following block of code, we create a save function from which we can save our task by simply clicking on the button and our task is saved into the Todolist.

def saveact():
    savecon = messagebox.askquestion(
        'Save confirmation', 'Save Your Progress?')
    if savecon.upper() == "YES":
        with open("SaveFile.txt", "w") as filehandle:
            for listitem in tasks:
                filehandle.write('%s\n' % listitem)
    else:
        pass

Block of code:

In the following block of code, we create a function load info and load act from which we can load our info into the list and also create a loadact function from which message box is generated if some wrong info enter.

def loadinfo():
    messagebox.showinfo(
        "info", "This is Todolist  \n created by Pythontpoint ",)


def loadact():
    loadcon = messagebox.askquestion(
        'Save Confirmation', 'save your progress?')
    if loadcon.upper() == "YES":
        tasks.clear()

        with open('SaveFile.txt', 'r') as filereader:
            for line in filereader:
                currentask = line
                tasks.append(currentask)
            updatetask()

    else:
        pass

Block of code:

In the following block of code, we create an exitapp function from which we can exit the app after completing the task.

def exitapp():
    confex = messagebox.askquestion(
        'Quit confirmation', 'Are you sue you want to quit?')
    if confex.upper() == "YES":
        wd.destroy()
    else:
        pass

Code:

In the following code, we will import the tkinter module and create a Todo list in which we can create our notes and add to the list.

from tkinter import *
import tkinter
import random
from tkinter import messagebox


def updatetask():
    clearlistbox()
    for utask in tasks:
        lbltask.insert("end", utask)

    lbldsp_count['text'] = numtask


def clearlistbox():
    lbltask.delete(0, "end")


def addtask():
    lbldisplay["text"] = ""
    Ntask = txtinput.get()
    if Ntask != "":
        tasks.append(Ntask)
        updatetask()
    else:
        lbldisplay["text"] = "please enter the text"
    txtinput.delete(0, 'end')


def deleteall():
    conf = messagebox.askquestion(
        'delet all??', 'are you sure to delete all task?')
    print(conf)
    if conf.upper() == "YES":
        global tasks

            for listitem in tasks:
                filehandle.write('%s\n' % listitem)
