Certainly! Here’s an informative tutorial on how to install Python 3 on CentOS with code examples.
Before installing Python 3, it’s a good practice to update the system’s package list and upgrade the installed packages to their latest versions. Open a terminal and run the following commands:
CentOS’s default repositories may not have the latest version of Python 3. To install the latest version, you can use the Software Collections (SCL) repository, which provides newer versions of software for CentOS.
First, enable the SCL repository:
Next, install Python 3 from the SCL repository:
This command will install Python 3.6 from the SCL repository. If you need a different version, such as Python 3.7 or 3.8, replace rh-python36 with rh-python37 or rh-python38 respectively.
Once Python 3 is installed, you can start using it. To access the Python 3 interpreter, you need to enable the Software Collections environment by running:
This command starts a new shell session with Python 3.6 enabled. You can now use Python 3.6 and its associated tools such as pip to install packages.
To verify that Python 3 was installed correctly, you can check the version:
This command should output something like Python 3.6.8 if Python 3.6 was installed successfully.
If you want to make Python 3.6 the default Python version on your system, you can create a symbolic link:
This command creates a symbolic link named python3 in /usr/local/bin that points to the Python 3.6 executable.
That’s it! You’ve successfully installed Python 3 on CentOS. You can now start using Python 3 for your development projects.
