How to Install Python 3 on CentOS
Python is a high level, dynamic, general purpose language. It was developed by Guido Van Rossum in 1991. Python's syntax allows developers to use fewer lines of code than any other programming language. It basically focuses on the code readability of program. Python 2.7 is installed by default on CentOS but we can install other versions like Python 3.5 and 3.6. In this tutorial, we are learning how to install Python 3.6.3 on CentOS.
Installation includes following steps.
1. Install IUS community Repository
In order to install Python 3.6 on CentOS, we need to first install IUS community repository which provides extra packages for Enterprise Linux. Execute the following command to install IUS community repository.
2. Install Python 3
Execute the following command to install python 3.6 on CentOS.
3. Verify Python
To verify if we have installed correct version of python, we just need to type python3.6 -V on the terminal. The command will show the version installed which is 3.6.4 in my case.
4. Working on Python's script mode
Just type python3.6 on the terminal to enter the Python's script mode. We can execute the python statements on this shell. Since, python 2 is by default installed on CentOS, hence typing python on the terminal takes us to the python2 shell, hence we have to type python3.6 to work on the desired python shell.
Execute the valid python statements which get interpreted and show the desired output on the terminal as shown below.
Hence, we have installed and get started with Python 3.
