WORKING WITH FILES IN PYTHON INTRODUCTION In this Python tutorial, you will learn how to work with files, that is, how to read and write files using python programming.

Python is a very powerful language and as you will learn in the following passages, how it is possible to open, read, write and make changes to created other files using our python script in the main.py file. For the purpose of this lesson, we will be using several in-built python functions such as open(), read(), write() and append() functions while explaining the two examples provided below to demonstrate how python handles files. The code editor that I have used for this purpose is the most popular cloud editor Replit  and you can easily find it from the source code that I have included at the end of this post. Code Example 1 my_file = open("index.html","w") my_file.write("<p> HELLO WORLD, th
