For example, to determine if (x1, x2) is greater than (y1, y2), Python tests x1 > y1. In this case, min() and max() use Python’s internal rules to compare tuples and find the smallest and largest items in the input dictionary. To explore the standard behavior of min() and max(), you can start by calling each function with either a single iterable as an argument or with two or more regular arguments. The alternative behavior is to use a single-argument function to modify the comparison criteria before finding the smallest and largest values. The standard behavior for each is to return the minimum or maximum value through straightforward comparison of the input data as it stands. Whether you’re using Python’s min() or max(), you can use the function to achieve two slightly different behaviors. What’s their job? They take care of finding the smallest and largest values in their input data. They mostly apply to iterables, but you can use them with multiple regular arguments as well. Two examples of these functions are min() and max(). Python includes several built-in functions that make your life more pleasant and productive because they mean you don’t need to reinvent the wheel.

To get the most out of this tutorial, you should have some previous knowledge of Python programming, including topics like for loops, functions, list comprehensions, and generator expressions.

Finally, you’ll code your own versions of min() and max() in pure Python, which can help you understand how these functions work internally.įree Bonus: 5 Thoughts On Python Mastery, a free course for Python developers that shows you the roadmap and the mindset you’ll need to take your Python skills to the next level. Once you have this knowledge under your belt, then you’ll be prepared to write a bunch of practical examples that will showcase the usefulness of min() and max().

You’ll try out some of those use cases here. Even though these might seem like fairly basic computations, they turn out to have many interesting use cases in real-world programing. Python’s built-in min() and max() functions come in handy when you need to find the smallest and largest values in an iterable or in a series of regular arguments.
