How To Install Python 3 On Centos 7

Python is an open up, powerful, interpreted, and easy to learn programming linguistic communication that supports multiple platforms. It is one of the well-nigh preferred programming languages in the fields of Data Analytics and Machine Learning.

It offers an extensive set of in-built and portable libraries that can be easily included to extend your Python project. Further, it has broad back up for object-oriented and functional programming practices of software engineering.

Python currently offers both Python ii.x and Python 3.x, which are not fully uniform with each other and have several differences. Hence the selection of using either of them should be a planned conclusion based on your current environment and needs. Most of the Linux distributions come pre-installed with some Python version due to its extensive use in OS libraries and software.

This commodity will cover the installation of Python three on CentOS, Ubuntu, and Windows-based platforms. Python three can be installed forth with Python 2, simply you need to be careful in specifying the system's default Python interpreter.

Python iii on CentOS 6.10/7.ten

For CentOS 6.ten/7.10 or RHEL based distribution, yous can install Python 3 using yum.

          $ sudo yum install python3        

When prompted, please confirm past pressing 'y':

          Is this ok [y/d/North]: y
