Exercise 4: Explore Generators

Practice writing a fake weather prediction generator.

We'll cover the following

Problem statement

This chapter explains how to write functions that return generators and multiple values. First, consider how to generate the two random values. Evaluate the conditions they represent for being harsh and choose accordingly: return or yield.

Task

Write a function that returns a "weather Oracle", similar to the fortune teller in the lesson "yield, do not return." The Oracle returns a random integer temperature from -89°C to 57°C (not inclusive) and a random integer humidity in the range from zero to 100 (inclusive). The generator stops either after the pre-specified number of attempts or when the generated weather conditions are too harsh (when temperature < -40°C and humidity <= 50), whichever comes first.
