Beginner’s Guide to Installing Python 3.9 on Ubuntu
Installing Python 3.9 on Ubuntu unlocks the door to a realm of enhanced coding possibilities. Python’s latest iteration boasts numerous upgrades, vital for developers seeking to utilize the most recent advancements in this universal language. This guide endeavors to streamline the setup process on an Ubuntu system, so you can seamlessly integrate Python 3.9 into your programming arsenal.
Essentials Before You Start
Prioritize preparing your Ubuntu workstation by verifying administrative privileges, securing an uninterrupted internet connection, and sharpening your command-line expertise.
System Update
Commence by updating system packages:
sudo apt update
sudo apt upgrade
A thorough update minimizes conflict during new installations.
Python 3.9 Acquisition
To obtain Python 3.9, execute:
sudo apt install python3.9
This command retrieves the latest package straight from the Ubuntu repository.
Compiling from Source
For custom feature requirements, consider compiling Python from source. Begin by installing prerequisites:
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev \
libnss3-dev libssl-dev libreadline-dev libffi-dev curl
Subsequently, download and unpack the Python 3.9 source:
wget https://www.python.org/ftp/python/3.9.x/Python-3.9.x.tgz
tar -xf Python-3.9.x.tgz
cd Python-3.9.x
Configure and compile the code:
./configure --enable-optimizations
make -j 8
sudo make altinstall
Adjust the ‘8’ to match your CPU cores count for faster compilation.
Confirming Your Installation
Post-installation, ensure success by checking the version:
python3.9 --version
The correct version number should confirm the installation.
Default Python Version
To elevate Python 3.9 as your default, configure your system alternatives:
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.9 1
sudo update-alternatives --config python
Select Python 3.9 from the ensuing options.
Pip Configuration
It’s crucial to set up pip, the Python package manager:
sudo apt install python3.9-venv python3.9-distutils
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3.9 get-pip.py
With pip installed, package management becomes a breeze.
Utilizing Virtual Environments
Efficient dependency management is achieved through virtual environments:
python3.9 -m venv myprojectenv
source myprojectenv/bin/activate
To exit, simply use ‘deactivate’.
Ubuntu Python 3.9 Practices
Finally, embrace best practices: stay updated, use virtual environments, adhere to PEP 8, and keep abreast with Python’s evolution.
Embarking on Python 3.9 Development
Through these steps, your Ubuntu system is now primed with Python 3.9, setting the stage for innovative software development.
