How To Install Python 3.4.5 from Apt

Ubuntu 14

In this article, we will guide you through the process of installing Python 3.4.5 from Apt. Python is a powerful, versatile programming language that is widely used in various fields such as web development, data analysis, artificial intelligence, and more.

Please note that Python 3.4.5 is an older version of Python, and it’s recommended to use the latest version whenever possible. However, if you have a specific need for Python 3.4.5, this guide will help you install it on your system.

Quick Answer

To install Python 3.4.5 from Apt, you need to add the deadsnakes PPA to your system, update the package lists, and then install Python 3.4.5 using the apt-get command. After installation, you can verify the installation by checking the Python version.

Pre-requisites

Before we start, ensure that you have administrative access to your system. You will need to use sudo (superuser do) command, which allows a permitted user to execute a command as the superuser or another user.

Adding the Deadsnakes PPA

The first step in installing Python 3.4.5 is to add the deadsnakes PPA (Personal Package Archive) to your system. Deadsnakes is a PPA that contains several different versions of Python, including 3.4.5.

To add the deadsnakes PPA, open your terminal and run the following command:

sudo add-apt-repository ppa:deadsnakes/ppa

The sudo command runs the following command as the superuser. add-apt-repository is a script which adds an external APT repository to either /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/. In this case, it’s adding the deadsnakes PPA.

Updating the Package Lists

After adding the PPA, it’s important to update your system’s package list to include the new packages from the deadsnakes PPA. To do this, run the following command:

sudo apt-get update

The apt-get update command fetches the package lists from the repositories and “updates” them to get information on the newest versions of packages and their dependencies.

Installing Python 3.4.5

With the package lists updated, you can now install Python 3.4.5. To do this, run the following command:

sudo apt-get install python3.4

The apt-get install command installs the specified package, in this case, python3.4.

Verifying the Installation

After the installation is complete, you can verify that Python 3.4.5 is installed correctly by checking its version. To do this, run the following command:

python3.4 --version

This command should return a response like Python 3.4.5, indicating that the correct version of Python has been installed.

Conclusion

In this article, we’ve walked through the process of installing Python 3.4.5 from Apt. Remember, it’s generally recommended to use the latest version of Python, but if you have a specific need for Python 3.4.5, this guide should have helped you install it on your system.

If you need to manage multiple versions of Python on your system, consider using a tool like virtualenv, which allows you to create isolated Python environments. You can read more about virtualenv at the official virtualenv documentation.

As always, if you have any questions or run into any problems, don’t hesitate to ask for help. The Python community is very active and there are plenty of forums and resources available to help you solve any problems you might encounter.

Can I install Python 3.4.5 alongside other versions of Python?

Yes, you can have multiple versions of Python installed on your system. However, it’s important to manage them properly to avoid conflicts. Tools like virtualenv or conda can help you create isolated Python environments for different versions.

Can I use this installation method on any operating system?

No, this installation method is specifically for systems that use the apt package manager, such as Ubuntu or Debian. For other operating systems, you will need to use different installation methods.

How can I uninstall Python 3.4.5 if I no longer need it?

To uninstall Python 3.4.5, you can use the apt-get command with the remove option. Run sudo apt-get remove python3.4 to remove Python 3.4.5 from your system. However, be cautious when removing Python versions, as it may affect other applications that depend on it.

Can I switch between different versions of Python after installing Python 3.4.5?

Yes, you can switch between different versions of Python using tools like update-alternatives or by specifying the version when running a Python script. However, it’s important to be mindful of dependencies and ensure that the required packages are installed for each version.
