This outer for loop gives us numbers in descending order starting with 5 going on till 1. In the outer for loop, we increment the value of a with 1. After that, we set the inner for loop using this command: for j in range(1, i + 1). In the first iteration, the value of ‘i...
The base case (the firstcase) returns0; therefore, summing only works for the types we can add with numbers. Note that Python does not know how to add text strings and numbers. So, we can use the class pattern to restrict our pattern to match integers only. The class pattern is simila...
For instance, imagine a dataset of mixed records where each entry can be either a number, a list of numbers, or a dictionary with numerical values. Using pattern matching and comprehensions together, you can process this dataset in a single line: ...

Here, we have created a Car class with three methods: accelerate(), apply_brakes() and assign_driver(). We imported the random module and used it to generate numbers that set the car's speed after accelerating and applying the brakes. The assign_driver() method displays the car driver's...

We treat warnings as errors in our built.sbt settings, but if we didn’t, then calling checkY(100) would return found y! for all three numbers. The case y clause means “match anything because there is no type declaration, and assign it to this new variable named y.” The y in the...
