Introduction of Python
Python is the fastest and the smartest programming language and it is an object oriented language. Python has libraries that can be importedeasily and perform many operations; to import the libraries; we need to install the pythoninstallation package ( pip ). Python is an object-oriented programming language consisting of objects and classes; which consists of the code and data; the object-oriented programconsists of the data in terms of attributes and the code in terms of methods or functions.
Guido van Rossum discovered the python programming language in 1989. Python 3.0was released in 2016 and is mainly used by many companies.Python is mainly used in the machine learning and data science department asit deals with vast data. The python language can also be used in web development, theDjango and Flask are the frameworks used to create web applications using python.
The falcon is a Framework in python programming language which helps us to build the APIs in a faster and easier manner. Generally, the Falcon Framework is mainly used to build the app backend, high performance services. The Falcon framework is flexible and the fastest framework. The Falcon framework is Reliable and debuggable and it is the most robust framework we can easily create an application which is easier to run and most flexible.
- Debuggable: The falcon framework is debuggable that is it gives us the information about how we will get the input and the output. The unhandeled exceptions are never kept as private or it it’s never encapsulated.
- Reliable: We can depend on the Falcon Framework without any fear, the falcon does not depend on the libraries outside the framework, we can avoid the viruses attacking the app’s surface and we can avoid the bugs in our app so that our application will run faster. We can depend directly on the python framework without the help of another framework.
- Fast: The falcon framework is faster than any other framework we can create the applications easily and faster with the help of the falcon framework. The Falcon increases it speed up by compiling the file itself with the Cython and it also works with the PyPy.
- Flexible: The Falcon Framework is more flexible than any other framework it gives the freedom to the user to edit the data easily and we can input any data easily into the framework with the help of this framework. We can open the file easily and run the code flexibly with the help of Falcon framework
Creating the API using Falcon
The first factor we`ll do is install Falcon within a contemporary virtualenv. thereto finish, let`s produce a replacement project folder known as “look”, and got wind of a virtual surroundings inside it:
$ mkdir look
$ cd look
$ virtualenv .venv
$ source .venv/bin/activate
$ pip install falcon I
t`s customary for the project`s commanding module to be known as constant because the project, thus let`s produce Another “look” folder within the primary one and mark it as a python module by making an empty redness.py come in it:
$ mkdir look
$ bit look/__init__.py
Next, let`s produce a replacement file that may be the entry purpose into your app:
$ bit look/app.py
Now, open app.py in your favorite text editor and add the subsequent lines:
app = application = falcon.App()
This code creates your WSGI application and aliases it as app. you'll use any variable names you wish, however we`ll use application since that's what Gunicorn.
Next let`s take a glance at the falcon.App class. Install and begin IPython.
$ pip can install ipython
Check the invocable falcon.App by typing:
: Import Falcon
: falcon.App.__call__? A
Alternatively, you'll use the quality Python help() perform.
The strategy signature. env and start_responsear commonplace WSGI parameters. Falcon adds a skinny abstraction to those parameters thus you do not ought to manipulate them directly. The Falcon framework comes with in depth inline documentation that may be queried mistreatment the techniques on top of. In addition to IPython, the Python community maintains many powerful REPLs you may need to do, like bpython and ptpython. App hosting Now that we've got a basic Falcon app, let's strive it out on our WSGI server. Open a replacement terminal and run:
$ source .venv/bin/activate
$ pip install guncorn
$ gunicorn - Reload Look.app
