Many of the functions in this chapter are from a library called re. This is built into base python, so you do not need to install it! We have already seen many examples so far of objects that have the string data type.

These might be referred to as str or character or object, depending on the library we are using to check type. String objects can be combined with the + operator: However, they cannot be subtracted, divided, or multiplied! There was an error while loading. Please reload this page.

This section will cover some of Python's built-in string methods and formatting operations, before moving on to a quick guide to the extremely useful subject of regular expressions. Such string manipulation patterns come up often in the context of data science work, and is one big perk of Python in this context.

Strings in Python can be defined using either single or double quotations (they are functionally equivalent): In addition, it is possible to define multi-line strings using a triple-quote syntax: You can order print and ebook versions of Think Python 3e from Bookshop.org and Amazon. Strings are not like integers, floats, and booleans. A string is a sequence, which means it contains multiple values in a particular order. In this chapter we’ll see how to access the values that make up a string, and we’ll use functions that process strings.

We’ll also use regular expressions, which are a powerful tool for finding patterns in a string and performing operations like search and replace. As an exercise, you’ll have a chance to apply these tools to a word game called Wordle. A string is a sequence of characters. A character can be a letter (in almost any alphabet), a digit, a punctuation mark, or white space. There was an error while loading. Please reload this page.
