How To Install Python 3.4 on Ubuntu

Ubuntu 13

In this detailed guide, we will walk you through the process of installing Python 3.4 on your Ubuntu system. Python is a versatile and popular programming language, widely used for web development, scripting, data analysis, and artificial intelligence. Having Python set up on your system can open the door to a wide range of coding opportunities.

Quick Answer

To install Python 3.4 on Ubuntu, open the terminal and enter the command "sudo apt-get install python3.4". After the installation is complete, you can verify it by checking the Python version using the command "python3 -V". Remember to use the "python3" command to execute Python scripts.

Checking for Existing Python Installation

Before we begin the installation, it’s a good idea to check if Python is already installed on your Ubuntu system. Open the terminal by pressing Ctrl + Alt + T and type the following command:

python3 -V

This command checks the version of Python 3 installed on your system. If the output shows ‘Python 3.4.x’, then Python 3.4 is already installed. If not, proceed with the following steps.

Installing Python 3.4

To install Python 3.4, use the apt-get command, which is a powerful command-line tool used for package management in Ubuntu. The install parameter indicates that we want to install a package, and python3.4 is the name of the package we want to install. Type the following command into the terminal:

sudo apt-get install python3.4

You may be prompted to enter your password since the sudo command runs a command with superuser permissions.

After the installation is complete, you can verify the installation by checking the Python version again:

python3 -V

Using Python 3.4

Once Python 3.4 is installed, you can start using it by typing python3 in the terminal. For instance, to execute a Python script named file.py, you would use the following command:

python3 file.py

Working with Python IDLE

Python IDLE is not a necessity if you have a text editor like Sublime Text or Atom. You can write your Python code in these text editors and execute it using the terminal with the python3 command. However, if you prefer to use Python IDLE, you can install it using the following command:

sudo apt-get install idle-python3.4

Conclusion

This guide has walked you through the process of installing Python 3.4 on Ubuntu, checking your Python version, and running Python scripts. Remember, while you can create an alias to make python command refer to python3, it’s not recommended as it might cause compatibility issues with other programs that rely on Python 2.7.

Once Python 3.4 is installed, you can start using it by typing python3 in the terminal. For example, to execute a Python script named file.py, you would use the command python3 file.py.

Can I use a text editor instead of Python IDLE?

Yes, you can use a text editor like Sublime Text or Atom to write your Python code. After writing the code, you can execute it using the terminal with the python3 command. Python IDLE is not necessary, but if you prefer to use it, you can install it using the command sudo apt-get install idle-python3.4.

Is it recommended to create an alias for `python` to refer to `python3`?
