The 23 Most Common Python String Methods and Functions

Learning common Python string methods is easier than it sounds as Python is very flexible with its data types. Most programming languages require you to declare what kind of variable you are using beforehand, whether an integer or string or another type. Python doesn’t. Python is a dynamically typed, interpreted language.

Within Python, variables are strictly typed (they have a single type) and dynamically typed (you don’t need to declare the variable’s type when you declare it). As with many other languages, a “string” in Python is just a sequence of characters. 

Because of that, you sometimes need to validate strings in Python or format them. In this tutorial, we’ll look at the most common Python string methods.

What is a “string” in Python?

A string is any variable that falls between single quotes (‘Hello!’) or double quotes (“Hello!”). Declaring a string is simple:

sstring = “1” = “Hello, world!”

Because Python doesn’t provide for static typing, you don’t need to do anything else. For instance, in other languages, you’d need to declare:

str $stringGreeting = “Hello, world!”;

But in Python, you can have a variable like this:

string = “1”

This is a string. But it’s also a number. In other words, in most Python operations, you’ll be able to use that as an integer rather than as a string. It’s both.

Keep this in mind as you look at some of the most popular Python string methods or dig into Python programming projects.
