But this is a learning exercise, and we're talking about lists. Now that we have our netmask, we can calculate the network IP. We'll start by creating an empty list in which to store our result. Then we'll iter

So, before you check out the implementation below, you might take some time and try to solve this by yourself as a learning exercise. Ready? Here’s how you might implement this functionality using a context manager class: Python class Indenter: def __init__(self): self.level = -1 ...
Note: This tutorial is adapted from the chapter “Numbers and Math” in Python Basics: A Practical Introduction to Python 3. If you enjoy what you’re reading, then be sure to check out the rest of the book.The number 0.1 can be represented as the fraction 1/10. Both the number 0.1...

Exercise 4:Add code to the above program to figure out who has the most messages in the file. After all the data has been read and the dictionary has been created, look through the dictionary using a maximum loop (see Chapter 5: Maximum and minimum loops) to find who has the most mes...
Recall thevowels7.pyprogram from the end of the last chapter, which, given a word, prints the vowels contained in that word: Let’s imagine you plan to use these five lines of code many times in a much larger program. The last thing you’ll want to do is copy and paste this code...
You’ll learn how to save data to files on the hard drive in Chapter 8. The keys(), values(), and items() Methods There are three dictionary methods that will return list-like values of the dictionary’s keys, values, or both keys and values: keys(), values(), and items(). ...
Just read each exercise, type in its sample code precisely (no copy-and-paste!), and make the programs run. As you read, type, fix your mistakes, and watch the results, you'll learn how software works, how programming works, what good programs look like, and how to read, write, ...
