How to Install Python 3.8 on Ubuntu 22.04
Step 1 – Update Your Server
Before you consider installing any new packages, it is advisable to run a system-wide update using the apt update or apt-get update command as shown below. All of your packages will be installed in their most recent iterations, lowering the possibility of any broken package errors.
sudo apt update
Step 2 – Install Python 3.8
You can install whatever version of python3 best suits your requirements, by using deadsnakes PPA, we'll install python 3.8, First, add the PPA:
sudo add-apt-repository ppa:deadsnakes/ppa
Now, you can install the required version of Python:
sudo apt install python3.8 -y
Step 3 – Check Python Version
Using the python3.8 —version command, you may determine the installed version of Python. As you can see, the number is 3.8.17.
python3.8 --version
Output
Python 3.8.17
Step 4 – Write your First Python Program
You must now be wondering how we can verify the use of the Python tool. In order to verify, you can create a simple Python file and run it. Here's an example of a simple Python program that prints the message hello world using our favorite nano editor, we will create a new file called hello.py and write a print statement to display hello world, as demonstrated below.
nano hello.py
Enter the below program:
print("Hello World !!")
Execute the program file:
python3.8 hello.py
Output
Hello World !!
Step 5 – Remove Python 3.8
You might wonder if the python3.8 that we installed before can be removed. Well, I would advise against it because it's likely that some program that depends on this version may be affected. However, if you are certain that you don't need it any longer, you may simply uninstall it by using the following command:
sudo apt remove python3.8 -y
# OR
sudo apt-get remove python3.8 -yapt remove python3 -y or apt-get remove python3 -y command, even accidentally, as it will remove all the packages related to python3 without your permission. Running this command will have severe consequences for your server. Therefore, practice caution while performing commands, especially if they are on a production server.FAQs to Install Python 3.8 on Ubuntu 22.04
