Python is a popular programming language used by developers worldwide. It is constantly evolving, with new versions being released regularly. If you are using Ubuntu 18.04 and want to update your Python3 installation to the latest version, this article will guide you through the process.
Step 1: Check Current Python Version
Before updating Python, it's important to know which version you currently have installed on your system. Open a terminal by pressing Ctrl + Alt + T and type the following command:
python3 --version
This will display the current Python version installed on your system. Note it down for reference.
Step 2: Update System Packages
Before updating Python, it's a good idea to update your system packages to ensure you have the latest versions of all dependencies. Run the following commands in your terminal:
sudo apt updatesudo apt upgrade
This will update all the packages on your system to their latest versions.
Step 3: Install Python3 PIP
PIP is a package manager for Python that allows you to easily install and manage Python libraries. To install PIP, run the following command:
sudo apt install python3-pip
Enter your password when prompted, and PIP will be installed on your system.
Step 4: Update Python3
Now that you have PIP installed, you can use it to update Python3. Open a terminal and run the following command:
pip3 install --upgrade python
This command will upgrade your Python3 installation to the latest version available.
Step 5: Verify Python Version
After the installation is complete, verify that Python has been updated successfully. Run the following command:
python3 --version
The output should display the new version of Python that you just installed.
Step 6: Update Python Packages
Updating Python itself is not enough; you also need to update any installed Python packages. To do this, run the following command:
pip3 list --outdated
This command will display a list of outdated packages. To update all the packages, run:
pip3 install --upgrade --upgrade-strategy eager
This will update all the outdated packages to their latest versions.
Step 7: Verify Package Updates
After updating the packages, it's a good idea to verify that the updates were successful. Run the following command to see the updated versions:
pip3 list
This will display a list of installed packages along with their versions. Make sure the versions have been updated as expected.
