First, we create a model file (let’s name it “ ezw_model.py“) under our working directory. Okay, we are now going to make our web app under the Model-View-Controller ( MVC) pattern in the Flask framework. The Model, the View and the Controller in the Flask To start our virtual environment with required libraries. When we are ready, we can run: >pipenv shell That’s it! And the Pipfile.lock is the file for storing version and environment details.
#EASYWEATHER JQUERY INSTALL#
Thus we can bring the Pipfile to a new location and install the dependencies, by typing: >pipenv install The Pipfile is the list of our dependencies. Then we will find Pipfile and Pipfile.lock files generated in our working directory. Requests – the name says it all, a HTTP library :]].Flask-CORS – an optional module for CORS handling (more details later).Flask – a micro web application framework.When the virtual environment is set, we can install following modules with pipenv:
#EASYWEATHER JQUERY FOR MAC#
(Note: for Mac users with Anaconda Python, when you face “dyld: Library not loaded” error, you may need to run Anaconda Distribution of virtualenv first) >conda install virtualenv >mkdir ezwĪnd we initialize a Python 3 environment. Let’s call it “ezw” then (stands for EZ Weather forecast, okay, I admit it, I am a huge wrestling mask, EZW! EZW! EZW!). Start our project with pipenvĪfter the installation of pipenv, we can set up a directory for our project. We can create a virtual environment from it, then install / uninstall modules within the environment and * automatically* maintain the list of the modules. The pipenv is a combination of virtual environment and pip.
Pipenv is not a functional module in our project, but an officially recommended Python packaging tool from . Before we go further in our development, let’s use pip to install a Python module, the “ pipenv” for our development environment. Luckily we are in the Python world, so “fast and easy” is never a miracle to us. Other than the “single-page web app” requirement, we have another hidden requirement as well, it is “fast and easy” (who doesn’t like fast and easy?). Isn’t it cool? Yeah! Okay, requirement is defined, let’s build our project! Then we can run the weather forecast tool on a browser in anywhere. It would be better if we can make a single-page Flask web app. Yes, it is fast and easy, but it is just not that convenient to run anything on a command prompt.

We have tried to code an Easy Weather Forecast Tool with Python.
