Installing Python 3.7 on Ubuntu: A Comprehensive Guide

Python is a popular programming language used for various applications, including data analysis, artificial intelligence, web development, and automation. Ubuntu is a widely used operating system that provides a reliable platform for Python developers.

If you’re interested in learning how to install Python 3.7 on Ubuntu, you’ve come to the right place. In this article, we’ll explore two methods of installation: using Apt and from source.

Installing Python 3.7 on Ubuntu with Apt

The Apt package manager is a convenient tool for installing software on Ubuntu. One way to install Python 3.7 on Ubuntu is by adding the deadsnakes PPA repository and installing Python 3.7 with Apt.

Follow the steps below. Step 1: Adding the deadsnakes PPA

PPA stands for Personal Package Archive.

deadsnakes is a trusted PPA that provides Python versions that are not included in the default Ubuntu repositories. Here’s how to add the deadsnakes PPA repository:

– Open a terminal window.

– Type the following command and press Enter:

sudo add-apt-repository ppa:deadsnakes/ppa

– Type your password when prompted, and then press Enter. Step 2: Installing Python 3.7 with Apt

Once you’ve added the deadsnakes PPA repository, you can install Python 3.7 with the following command:

sudo apt install python3.7

The installation process may take a few minutes.

To confirm that Python 3.7 is installed, run the following command:

python3.7 –version

You should see something like this:

Python 3.7.12

Congratulations! You’ve successfully installed Python 3.7 on Ubuntu using Apt. Installing Python 3.7 on Ubuntu from Source

If you prefer to install Python 3.7 from source, you can follow the instructions below.

Be warned, this method requires more steps than using Apt. Step 1: Downloading and compiling Python 3.7

The first step is to download the Python 3.7 source code.

You can do this by visiting the official Python website and downloading the source code for version 3.7. Once you’ve downloaded the source code, navigate to the directory where the file is located and extract it. You can do this by typing the following command:

tar -xzf Python-3.7.12.tgz

Next, navigate inside the extracted directory by typing:

cd Python-3.7.12

Now it’s time to configure the build.

Run the following command:

./configure –enable-optimizations

This step may take a few minutes to complete. Once it’s finished, you can start the build by typing:

make -j 8

The -j option specifies the number of cores to use for the build. You can adjust this number based on the number of cores in your system.

This step may take a while to complete, depending on the speed of your system. Step 2: Installing Python 3.7 from source

Once the build is finished, you can install Python 3.7 from source by typing:

sudo make altinstall

The altinstall option tells make to install Python 3.7 alongside any other Python versions you already have installed. This step should be very quick, and you should now have Python 3.7 installed on your system.

Conclusion

In this article, we explored two methods for installing Python 3.7 on Ubuntu: using Apt and from source. While using Apt is quicker and simpler, compiling Python from source gives you more control over the installation process.

Hopefully, this guide has been helpful in helping you get started with Python on Ubuntu. Good luck, and happy programming!

In this comprehensive guide, we have explored two methods of installing Python 3.7 on Ubuntu: using Apt and from source.

We have covered the steps you need to take to add the deadsnakes PPA, install Python 3.7 with Apt, download and compile Python 3.7 source code, and install Python 3.7 from source. In this addition, we will go further and discuss how to verify that Python 3.7 is installed correctly on your system.

Verifying Python 3.7 Installation

After installing Python 3.7 on your system, you might want to verify that it is installed correctly and working as expected. There are different ways to do this, but the easiest way is to use the python3.7 –version command.

To do this, open a terminal window and type the command:

python3.7 –version

You should see a message that displays the version of Python 3.7 on your system. For example, if Python 3.7.12 is installed, the message should look something like this:

Python 3.7.12

If you see a message that says “command not found,” it means that Python 3.7 is not installed or is not properly configured on your system.

Another way to verify that Python 3.7 is installed correctly is to run a Python script. You can create a simple script that prints the version of Python and then run it with Python 3.7. Here’s how:

Step 1: Open a text editor and create a new file.

Step 2: Type the following code into the file:

import sys

print(sys.version_info)

Step 3: Save the file with a descriptive name like “python37test.py”. Step 4: Open a terminal window and navigate to the directory where the file is saved.

Step 5: Run the script with Python 3.7 by typing the following command:

python3.7 python37test.py

You should see a message that displays the version of Python 3.7 on your system. For example, if Python 3.7.12 is installed, the message should look something like this:

sys.version_info(major=3, minor=7, micro=12, releaselevel=’final’, serial=0)

If you see an error message, it means that Python 3.7 is not installed or is not properly configured on your system.

Conclusion

After following this guide, you should now be able to install Python 3.7 on Ubuntu using Apt or from source. You should also be able to verify that Python 3.7 is installed correctly on your system by using the python3.7 –version command or by running a Python script.

Python 3.7 is a popular version of Python that comes with many new features and improvements. By learning how to install Python 3.7 on Ubuntu, you will have access to these features and be able to take advantage of the many tools and libraries available in Python’s ecosystem.

Installing Python 3.7 on Ubuntu can seem daunting at first, but with this comprehensive guide, you can easily install Python 3.7 using Apt or from source. Adding the deadsnakes PPA helps with the installation process with Apt, while downloading and compiling the Python 3.7 source code gives you more control during installation.

After installation, you must verify the installation using the Python version command or running a simple Python script. Python 3.7 is a popular version that comes with new features and improvements and is used across various applications.

Learning how to install and verify Python 3.7 on Ubuntu is, therefore, crucial for any serious Python programmer.
