Here, we will use the string " I like " (notice the spaces at the beginning and end). The only change we need to make to the code in the last example is to change the string on which we call join(). Print a List on a Single Line with a Custom SeparatorĪs I mentioned in the last section, we can also use the join() method to print out our list with a custom delimiter or separator. We print this result out, and the output is reminiscent of the output of some of the previous methods at which we’ve already looked. This effectively joins each element of our list and connects them with a space. Then, as I mentioned before, we call the string method join() on this string, and we pass it in our list. In this case, the string is just a space. What’s different is that we start by specifying a string. You can see in the code that we are using our good friend, the print() method, to print the list. ![]() Image 6 - Printing a Python list with the join() method (image by author) Let’s print some formatted strings based on the contents of our Python list! You can write almost the same thing in Python to loop through your Python list. You might say something like, “For each item in my grocery list, I want to buy this quantity”. Imagine you want to describe your intention of buying the items on your grocery list to a friend. ![]() What makes this technique so intuitive is that it reads less like programming and more like written English! Perhaps one of the most intuitive ways to access and manipulate the information in a list is with a for loop. Next up, I am going to show you how you can start to leverage some of Python’s other built-in features to access information in lists much more efficiently. After all, we had to specify each element we wanted to print individually in the example above. Now, that’s certainly useful, but you might be wondering how any of this is more efficient than working with normal variables. Notice how I use the indices 0 and 2 to represent the first and third elements since Python indexing begins with 0. Image 1 - Printing individual list elements in Python (image by author) Now we’ll take a look at how to define lists and access the information within them. While array and list structures in some programming languages require learning funky syntax and have strict rules about what data types they can hold, Python lists have none of that! This makes them super simple to use and equally flexible. If a person wants to store a sequence of to-do’s so they’ll remember them throughout the day, they may write a to-do list. This is not unlike analog lists that you may be familiar with. More specifically, they store sequences of information. Like variables, Python lists also store information. This is part of what makes computers such terrific tools we can feed them a bunch of information, and they can remember it and manipulate it way more easily than humans can. Variables allow the programmer to store information, like numbers or strings of text, and reuse it efficiently. ![]() One of the most important features of any programming language is the ability to define variables.
