A note about Debian / Ubuntu Linux user
Make sure we update our repos:
sudo apt update
sudo apt upgrade
Use the following command to search for available versions of Python under Debian and Ubuntu Linux:
$ apt-cache search python | egrep "^python..[0-9] " --color
Here is what we see:
python3.8 - Interactive high-level object-oriented language (version 3.8) python2.7 - Interactive high-level object-oriented language (version 2.7) python3.9 - Interactive high-level object-oriented language (version 3.9)
Run the following command to install python version 2.x:
$ sudo apt-get install python2.7
Type the following command to install python version 3.8 or 3.9:
$ sudo apt-get install python3.8
## or ##
$ sudo apt-get install python3.9
Output indicating that I am installing Python 3.9 on Ubuntu 20.04 LTS or Debian 10/11:

Installing Python on a Red Hat (RHEL) / CentOS Linux user
Type the following command:
$ sudo yum install python
OR
# yum install python
See “RHEL 8 install Python 3 or Python 2 using yum” for more info.
How to install Python 2.x/3.x on SUSE or OpenSUSE Linux
Use the zypper command to search Python:
$ sudo zypper ref
$ sudo zypper search python-base
$ sudo zypper search python3-base
It seems Python 3 is already installed on my OpenSUSE Linux v15.2 server:
Loading repository data... Reading installed packages... S | Name | Summary | Type --+--------------------+---------------------------------------+----------- i | python3-base | Python 3 Interpreter and Stdlib Core | package | python3-base | Python 3 Interpreter and Stdlib Core | srcpackage | python3-base-32bit | Python 3 Interpreter and Stdlib Core | package | python3-base58 | Base58 and Base58Check implementation | package
If not installed, try:
sudo zypper install python3-base
## get version 2.x ##
sudo zypper install python2-base
How do I find out installed python version?
Type the following command:
$ python --version
Default Python version
Python 2.7.18
To see default Python 3.x version, type:
$ python3 --version
$ python3.8 --version
$ python3.9 --version
Installing latest Python 3.9 on Debian or Ubuntu using source code method
First install development tools on Debian / Ubuntu Linux as follows:
$ sudo apt install build-essential \
curl libbz2-dev \
libffi-dev libgdbm-dev \
libncurses5-dev libnss3-dev \
libreadline-dev libsqlite3-dev \
libssl-dev zlib1g-dev
Next, get latest version of Python. We can use wget to download file. You can also use curl to download file as follows:
$ VERSION="3.9.1"
$ wget "https://www.python.org/ftp/python/${VERSION}/Python-${VERSION}.tgz"
Extract the tgz archive or tarball as follows using the tar command:
$ tar -xvf Python-${VERSION}.tgz
Change directory using the cd command and configure build:
$ cd Python-${VERSION}
$ ./configure --enable-optimizations
Compile it using all CPU cores. We can pass the as follows on Linux and the nproc command returns the number of CPU cores available on your system:
$ make -j $(nproc)
Once compilation finished, install the Python on your system, run:
$ sudo make altinstall
That is all. Python 3.9.1 has been installed on your Linux system. Print Python version, run:
$ python3.9 --version
Summing up
You learned how to install Python’s latest stable version on popular Linux distros such as Debian, Ubuntu, SUSE/OpenSUSE, and RHEL/CentOS Linux.
