Chaining function invocations The built-in template functions we have been using operate pretty much as regular functions we use when writing our code. As such, we can actually chain their invocation, meaning that, for example, we can sort an array and then pass the result to the join functi...
last line, don't feel bad, it's just the way Python works. The result of an integer division in Python is always rounded towards minus infinity. If instead of flooring you want to truncate a number to an integer, you can use the built-inintfunction, like shown in the following ...
