This Python Wrapper retrives data from the Visual Crossing API. Visual Crossing has an extensive Weather API for both historical and forecast weather data, and they have a Free Tier API Key which enables up to 1000 calls per day.
In order to get started you must create an Account with Visual Crossing and then create an API Key. You do this by accessing this website and clicking on the Free plan. Then follow the instructions to create and account and store your key in a safe place.
Install the module by using this command in a terminal: pip install pyVisualCrossing
And then see test_module.py and async_test_module.py for usage examples, both standard and async. (Async example not yet created)
