How To Python In Ubuntu

Python is a versatile programming language, and Ubuntu is a popular Linux distribution. Combining these two technologies, you’ll be well on your way to developing powerful applications on a stable platform. In this blog post, we’ll guide you through the process of installing, setting up, and using Python in Ubuntu.

Step 1: Check if Python is Already Installed

Most recent versions of Ubuntu come with Python pre-installed. To verify the installed version(s), open the terminal and enter the following commands:

        python --version
        python3 --version
    

If you see a version number, then Python is already installed. If not, proceed to the next step to install it.

Step 2: Install Python

You can install Python using Ubuntu’s package manager, apt. To do this, first update the package list by running:

        sudo apt update
    

Next, install Python using the following command:

        sudo apt install python3
    

Once the installation is complete, verify the installed version by running:

        python3 --version
    

Step 3: Install pip (Python Package Manager)

pip is a package manager for Python, allowing you to easily install and manage Python libraries. To install pip, run the following command:

        sudo apt install python3-pip
    

After the installation is complete, verify the installed version of pip by running:

        pip3 --version
    

Step 4: Writing and Running Python Scripts

To write Python scripts, you can use any text editor you prefer. Some popular choices include Visual Studio Code, Sublime Text, or even the built-in gedit editor.

Once you’ve chosen an editor, create a new file with a “.py” extension, such as “hello_world.py”. Write the following Python code inside the file:

        print("Hello, World!")
    

Save the file and open the terminal. Navigate to the directory containing the script and run the following command to execute the Python script:

        python3 hello_world.py
    

You should see the output “Hello, World!” in the terminal.

Step 5: Installing and Using Python Libraries

With pip, you can easily install Python libraries. For example, let’s install the popular library, Requests:

        pip3 install requests
    

Now you can use the Requests library in your Python scripts. Create a new file called “http_request.py” and add the following code:

        import requests

        response = requests.get("https://api.ipify.org?format=json")
        data = response.json()

        print("Your public IP address is:", data["ip"])
    

Run the script with the following command:

        python3 http_request.py
    

Your public IP address should be displayed in the terminal.

Conclusion

Now that you know how to install and use Python in Ubuntu, you’re ready to start developing powerful applications. Remember to explore the vast ecosystem of Python libraries to help accelerate your development process. Happy coding!
