Introduction
In this blog, we will learn how to Upload the file and read it in CherryPy python. It seems easy to do so, but still, it has a few steps which we have to keep in mind while Uploading the file and reading it in CherryPy python, which are explained completely below. So let's start.
Uploading the File and Reading it in CherryPy Python
CherryPy is a Python web framework that provides a user-friendly interface to the HTTP protocol for Python developers. It's also known as a web application library. It enables developers to create web apps in the same manner that they would create any other object-oriented Programming language. As a result, less source code is created in less time.
Requirements
The fundamental requirements for installing the CherryPy framework are as follows:
- Python version 2.4 or higher
- CherryPy 3.0

Installation
Use the following Command in the terminal to install Cherrypy:
Pip install cherrypy
Upload a File and Read its Contents
The following are the steps necessary to upload a file and read its content using Cherrypy:
- Create any text file to read or utilize an existing file.
- Create a user interface for uploading a file from the system.
- Create a Cherrypy program that reads a file and displays its contents.
