Environmental Setup for CherryPy

Introduction

Coders: I want to make a web application

Coding Ninja: Go Ahead, bro….

Coders: But I only have knowledge of Python, and I cannot do web development just with Python!

Coding Ninjas: Who told you this !!! Have you heard of CherryPy?

Coders: No, What is this CherryPy?

Coding Ninjas: CherryPy enables developers to create web apps in the same manner as they would any other object-oriented Python program. As a result, less source code is completed in less time.

Coders: This is very interesting; how to install and setup this CherryPy

Coding Ninjas: Well, I can tell you………..

Environmental Setup for CherryPy

CherryPy is a very famous Python framework. Web applications can be built or designed faster and more reliably with CherryPy. It's also known as a web application library. As it is based on object-oriented Python programming, it is noted for its simplicity, resulting in less source code in less time. 

Now we know what CherryPy is, so let's see its essential requirement for its Installation and Setup.

Requirements

CherryPy has no necessary system requirements. Pip automatically installs a Python-based distribution that is needed. Certain functions, however, will require the installation of additional packages. To make it easier to install other dependencies, cherryPy provide options to include.

• doc – for documentation-related matters
• json – for a personalized JSON processing library
• routes_dispatcher – dispatcher routes for declarative URL mapping
• ssl –  for OpenSSL bindings, helpful in Python environments where the ssl module is not installed
• testing
• Memcached_session – allows backend Memcached session

Python Version Supported

CherryPy works with Python 3.5 through Python 3.8.

Installation Process

CherryPy is simple to install using the standard Python package manager;  pip or setup-tools.

Easy Install

$ easy_install cherrypy

Pip Install

$ pip install cherrypy

You may also obtain the most recent CherryPy version by downloading the source code from Github:

GitHub Install

$ git clone https://github.com/cherrypy/cherrypy
$ cd cherrypy
$ python setup.py install

Installation Test

CherryPy includes a collection of easy tutorials that may be run once the package has been installed. 

$ python -m cherrypy.tutorial.tut01_helloworld

Navigate to http://127.0.0.1:8080 for output.

When run, the above program displays the following logs:

Output:

Run

The simplest way to run your application during development is as follows:

$ Python myapp.py

It will work well as long as myapp.py contains a "__main__" section.

Cherryd

The cherryd script, installed alongside CherryPy, may also be used to launch the application.

Some Common Commands:

• -e, –environment 

 Use the specified configuration environment (defaults to None)

• -c, –config

 Specify Config file

•  -i, –import

 Specify modules to import

•  -P, –path

  Add the given paths to the sys.path

•  -d

 Apply the given config environment
