FileDialog – This module provides the classes and inbuilt functions for creating file or directory selection windows.īefore getting started with code we need to install required libraries: Installation: $ sudo apt-get install python3-tk. 
MessageBox – This module provides the template classes and a variety of inbuilt functions for alerting the user, these message boxes can be an info message, an error message or ask yes/no message. Tkinter – This is one of the most Powerful, Widely Used and Platform Independent library available in Python for creating seamless and nice-looking GUI applications, it is very easy to use and understand different widgets provided by Tkinter. Introduction to the libraries and modules used In this, we will be using the Tkinter library and two additional modules supported by Tkinter, ‘MessageBox’ and ‘FileDialog’ for providing some additional functionality to our editor. So in this tutorial, we will be learning how to create a simple text editor using Python Programming Language. As though the ultimate work of a text editor is to edit files then too, choosing the best editor for programming is a trending topic of all-time in the tech industry, depending upon you can predict the power and importance of text editor in developer’s life. Text Editor is the first most and essential need of a software developer those are willing to write code or simply edit the existing one, working becomes easier due to the different functionality provided to the user, they are customizable according to the user needs. You can merely add something to the file.In this tutorial, we will learn how to create a text editor like notepad in Python. However, you cannot replace the line that is already there in the file through the seek and flush method. However, if you prefer to use read and write, always use seek operation to get to the line that is to be replaced and use flush once you finish writing the file. 
NOTE: Read here(not an official link), to learn better about dictionary methods. Just open the file in read mode with generator expression and keep a reference count to satisfy write operation. You can even keep a count and write based on count, if you are bothered about memory in this case. Replaced_text += line.replace(word, new_word) Words_replacer_dict = įor word, new_word in words_replacer_ems(): text_read = open('samiam.py', 'r').read() It will be good to use two descriptors - one for reading and other for writing, for readability and single write operation.
