Setting up a Python web development environment on OS X

Download this blogpost from https://codegive.com
python is a versatile and popular programming language for web development. setting up a python web development environment on os x (macos) is relatively straightforward, and in this tutorial, we will walk you through the process step by step. we'll be using python 3 for this tutorial.
before we begin, ensure you have the following prerequisites:
homebrew is a package manager for macos that makes it easy to install and manage software packages. open the terminal and run the following command to install homebrew:
follow the on-screen instructions to complete the installation.
macos comes with python 2 pre-installed, but we recommend using python 3 for web development. install python 3 using homebrew:
to verify the installation, run:
you should see the python 3 version.
using a virtual environment is a best practice to isolate your python projects. it allows you to install project-specific dependencies without affecting your system python. install virtualenv using pip (python's package manager):
now, create a new virtual environment for your project:
to activate the virtual environment, run:
you'll see (venv) in your terminal prompt, indicating that the virtual environment is active.
now that you have python 3 and a virtual environment set up, you can start installing packages required for web development. common packages include flask and django. for this example, we'll install flask:
let's create a simple flask application to ensure everything is working correctly. create a python file (e.g., app.py) with the following content:
to run your flask application, use the following command from the project directory:
your flask app will be accessible at http://127.0.0.1:5000/ in your web browser. you should see "hello, world!" displayed in the browser.
you've successfully set up a python web development environment on os x, installed python 3, created a virtual environment, installed necessary packages, and run a simple flask application. you're now ready to start buildin ...
