1-Day Python Build: What’s The Weather At The North Pole?

What's the weather at the North Pole?

This blog post is part of Anvil's Advent Calendar, a project where we build 24 apps in 24 days, and blog about it! That means this app was built in only a few hours; read on to see what our 8th of December app is.

Weather conditions can be pretty tough for Santa Claus and his Elves at the North Pole. With todays advent calendar app, you can find out whether the weather is being naughty or nice for Santa:

Of course, the app is built with nothing but Python!

Here's how it works:

We can start by building the app's UI by dragging and dropping components, like Labels, to display the weather information we want.

Then we just need to get an API key and store it as a secret in our app. We can then create a server function to send the HTTP request and get weather data back:

`@anvil.server.callable
def get_north_pole_weather():
  resp = anvil.http.request(f"http://dataservice.accuweather.com/currentconditions/v1/336714?apikey={anvil.secrets.get_secret('accuweather_key')}", json=True)
  return resp[0]

Then, we can set the properties of each front-end component, like a Label's display text, in client-side Python to display the weather data:

...
self.weather_description.text = weather_data['WeatherText']
self.temperature_celsius.text = str(weather_data['Temperature']['Metric']['Value']) + "°C"
...

And that’s all there is to it! We now have an app to check the weather at the North Pole.
