Tkinter can also be used to render the text file and load it on the canvas. Further, the text files can be used for other purposes like manipulating the data, grabbing the data, and rendering the data for other uses.Let us suppose that we have to read a text in the tkinter canvas file which contains more than 10, 000 lines of queries in it. It would take a long time to search for a particular query in the canvas after loading the text file. To handle such large text files, we can speed up the responsiveness of the file ... Read More

Sometimes, the tkinter frame gets resized automatically according to the size of the widgets. To make the frame constant in size, we have to stop the widgets to resize the frame. So there are three methods, Boolean pack_propagate(True/False) method prevents the resizing of the frame from the widget.resizable(x, y) method prevents the window to be resized.Pack(fill, expand) values which resize the window to its defined size in the geometry.Basically, all the widgets inside the tkinter frame will be responsive and cannot be resized.Examplefrom tkinter import * win= Tk() win.geometry("700x300") #Don't allow the screen to be resized win.resizable(0, 0) ...

JavaScript Object Notation, or JSON is a simple data format that is used to exchange data between many different languages. It is simple to read for people and simple for computers to parse. Python reads JSON text as a quoted-string that contains the value in each key-value mapping. Once parsed, it is accessible in Python as a dictionary object. JSON data can be encoded and decoded using the built-in package json in Python. You must first import the json library in order to work with files of the json type. Purposeco JSON Python to JSON conversion is done using serialization. ... Read More

Tkinter is a Python library that is used for creating and developing GUI-based applications. In this article, we will see how to remove text from a Label that will have some text in it.To remove text from a label, we will create an associated button that will act as a trigger for the Label.Example#import Tkinter Library from tkinter import * #Create an instance of tkinter frame win= Tk() #Define the size and geometry of the frame win.geometry("700x400") #Create a function for the Button Comman def remove_text():    text.config(text=" ") #Create a text Label text= Label(win, ...

Let us consider that we have created a listbox using the Listbox method in Tkinter and we want to remove multiple selected items from this list.In order to select the multiple list from the Listbox, we will use selectmode as MULTIPLE. Now iterating over the list, we can perform the delete operation using some buttons.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame or window win= Tk() #Set the geometry win.geometry("700x400") #Create a text Label label= Label(win, text="Select items from the list", font= ('Poppins bold', 18)) label.pack(pady= 20) #Define the function ...

BeautifulSoup is a python library that pulls out the data from HTML and XML files. Using BeautifulSoup, we can also remove the empty tags present in HTML or XML documents and further convert the given data into human readable files.First, we will install BeautifulSoup library in our local environment using the command: pip install beautifulsoup4Example#Import the BeautifulSoup library from bs4 import BeautifulSoup #Get the html document html_object = """ Python is an interpreted, high-level and general-purpose programming language. Python's design philosophy emphasizes code readability with its notable use of significant indentation. """ #Let us create the soup ... Read More

Sometimes, while creating an application, we need to interact with external programs and applications. In order to interact with the system's applications and programs, we have to use os Module in python.In this article, we will see how we can interact with external programs and open files using the OS module in Python.First, we will define a function that will open the chosen file using the filedialog library in Python. Then, we will print the path and open the file using the os module.Example# Import the required Libraries from tkinter import * from tkinter import filedialog import os #Create ... Read More

In Tkinter, sometimes, we may want to make a text widget disabled. To achieve this, we can set the text configuration as DISABLED. This will freeze the text widget and will make it read-only.In this example, we will create a text widget and a button which will allow users to disable or freeze the text widget instantly.Example#Import the library from tkinter import * #Create an instance of window win= Tk() #Set the geometry of the window win.geometry("700x400") def disable_button():    text.config(state= DISABLED) #Label Label(win, text="Type Something", font=('Helvetica bold', 25), fg="green").pack(pady=20) #Create a Text widget text= ...

Tkinter is widely used to create GUI based applications. It has many toolkits and functions or modules available which can be used to define the different attributes of a particular application. For building GUI applications it provides some widgets including buttons, text boxes and labels. We can customize the position of the widget and its coordinates on the tkinter frame using other functions and libraries.Let us suppose that we have created a text label widget which is having some position in the tkinter frame. Now, to get the actual coordinates of the widget, we can use the geometry methods available ... Read More

Tkinter allows developers to interact with the files inside the local system. In this article, we will see how to print a hardcopy of a file using Tkinter packages such as filedialog and win32api module.In order to import these packages, we have to first install these modules in our environment. To install win32api, we will use pip install pywin32Example#import the required libraries from tkinter import * from tkinter import filedialog import win32api #Create an instance of tkinter frame or window win= Tk() win.title('Print Hard Copy') win.geometry("700x400") #Define function def print_file():    file= filedialog.askopenfilename(initialdir="/", title="Select any file", filetypes=(("Text ...
