Unfortunately, a solution like this won’t work. As a result, concatenation can seem like a quick shortcut to string formatting: print("My name is " + name + ", and I am " + age + " years old.") If you’re like me, concatenation is something you learned when you first started to code. We’ll start from a few direct approaches, then we’ll move into some the for elegant solutions. Python string format free#Of course, feel free to swap the name and age with your name and age! SolutionsĪs it turns out, there are quite a few ways to format a string. Using these variables, we’ll want to construct the following sentence: print("My name is Jeremy, and I am 25 years old.") Python string format code#The following code snippet will serve as our base for the remainder of the article: name = "Jeremy" To get started, we’ll need a universal example which contains a few pitfalls like mixing numbers and strings. That said, I don’t you’re here to learn string formatting in C, so how do we accomplish the same thing in Python? In this article, we’ll take a look at several methods-some silly-just to illustrate how many ways there are to solve this problem. And, we can even specify how the numbers look in terms of padding and truncation. For example, numbers have their own set of specifiers: %d, %f, etc. Of course, string formatting gets more complicated as we introduce different data types. For instance, in languages like Java and C, string formatting relies on understanding concepts like variable arguments and format specifiers: printf("Hi, %s", Jeremy) # Prints "Hi, Jeremy" After all, the syntax varies from language to language which can feel like learning a metalanguage. Whether we’re trying to prompt a user or output a nice error message, string formatting can always be challenging. In addition to sharing all 6 solutions, I also run through performance testing, and I share a solution to the Mad Libs challenge.
