How To Install Python 3 and Set Up a Local Programming Environment on CentOS 7

If you're planning to develop Python applications on CentOS 7, it's essential to have a local programming environment set up with Python 3. This tutorial will guide you through the process of installing Python 3 and setting up a local programming environment on CentOS 7.

Step 1: Update CentOS 7

Before installing Python 3, it's important to update your CentOS 7 system to ensure you have the latest software packages. Run the following command:

sudo yum update

Step 2: Install Python 3

CentOS 7 comes with Python 2.7 installed by default, but Python 3 is not installed. To install Python 3, run the following command:

sudo yum install python3

Verify that Python 3 is installed by running the following command:

python3 --version

You should see the version of Python 3 installed on your system.

Step 3: Set Up a Virtual Environment

Setting up a virtual environment is recommended when working on Python projects. It helps to isolate your Python environment and manage your project dependencies. To set up a virtual environment, follow these steps:

  1. Install pip:
    2. sudo yum install python3-pip
  2. Install the virtualenv package:
    3. sudo pip3 install virtualenv
  3. Create a new virtual environment:
    4. virtualenv myenv
  4. Activate the virtual environment:
    5. source myenv/bin/activate

Once you've activated the virtual environment, you'll see the name of the environment in your terminal prompt.

Step 4: Install Additional Packages

You can now install any additional Python packages your project requires using pip. For example, to install Flask, run the following command:

pip install Flask

Step 5: Deactivate the Virtual Environment

Once you're done working in the virtual environment, you can deactivate it by running the following command:

deactivate

Your terminal prompt should now return to its original state.

Conclusion

In this tutorial, you learned how to install Python 3 and set up a local programming environment on CentOS 7. You also learned how to set up a virtual environment, install additional packages, and deactivate the virtual environment when you're done working on your project.
