Daisha, for example, soon learns that the following three lines all produce the same output: print("Hello, Daisha!") The vast majority of us began our careers with some version of this program: print("Hello, world!")Īs we start to advance a little further, we soon learn that we can also format strings in exciting ways by either passing multiple strings (or even other types) to the print function or by concatenating strings.
Next, we’ll take on what is probably the second-most common method you’ll find in modern Python codebases, the string format method, str.format.

We want to start slowly by discussing what beginners first learn about how to work with strings, then move on to the current favorite of most Python developers, formatted string literals (or “f strings”). Python has quite a few distinct ways to do this, and for any particular task, the format string you’ll need to use may be pretty specialized, so we’ll need to be selective about what string formatting techniques we cover. This article will discuss the different methods for formatting strings in Python. Formatting strings allows you to display data in a more readable and concise way. String formatting is an essential skill for any Python programmer to master. Most beginners begin learning how to format using string concatenation and print, but more flexible techniques include f strings and the string format method. String formatting is the process of injecting - or “interpolating” - other things into a string to get the result we want. Nevertheless, I’ve found over the years that I’m going to spend a lot of my time formatting strings on almost every project.
I realize that to many non-programmers, their idea of what we do involves a cross between slinging binary and reading the matrix. I’ve learned several programming languages throughout my career, and whenever I start to learn a new one, one of the first things I want to know about it is how to do string formatting. Note: this is part of a series of articles on Python for Beginners.
