Since we want to get the forecast only for today, let's collect all temperature information for today and process it later. The method parse_weather_data, implemented in the following code, takes a JSON string with weather data. Then it decodes it and starts to iterate over the data. If start_date is unassigned (it is the first iteration), we assign it the first day of the forecast that we have.
In the physical world we always come across Facades; when you turn on the computer, the operating system hides all the internal work of the computer because the OS provides a simplified interface to use the machine. The Facade Design Pattern An automobile is another example: you have a simple interface with steering wheel, gas, and brake pedals but you don't need to know exactly how the engine and the transmission work to drive a car. When you turn a key, the car's electronics sends multiple signals to different parts of the automobile subsystem through a single interface; the ignition key.
Instance It will return the singleton objects to all parts of the code that request it. Next, we'll create a class for creating a thread. name The following function traverses the website using BFS algorithm, finds links, and adds them to a set for further downloading. to_visit queue and saves it to the img directory. get('src') # Construct a full url. If the image url is relative, # it will be prepended with webpage domain. py [ 25 ] Creating Only One Object with the Singleton Pattern You should get the following output (your output may vary because the order in which the threads access resources is not predictable): If you go to the images directory, you will find the downloaded images there.
