Pattern matching and guards are combined in order to return an answer satisfying all uses. As pointed out earlier, case ... of expressions are pretty much the same thing as a bunch of function heads with guards. In fact we could have written our code the following way:...
If you define a function inside another function, then you’re creating aninner function, also known as a nested function. In Python, inner functions have direct access to the variables and names that you define in the enclosing function. This provides a mechanism for you to create helper fun...
