Python String Methods

Python provides a variety of built-in string methods that allow you to manipulate and work with strings. These methods can be used to change the case of a string, strip whitespace, replace substrings, split strings into lists, and more. Here are some common string methods in Python.

toUpperCase() and toLowerCase()

The toUpperCase() method converts all characters in a string to uppercase, while the toLowerCase() method converts all characters to lowercase. For example:

const text = 'Hello, World!';
const upperCaseText = text.toUpperCase();  // 'HELLO, WORLD!'
const lowerCaseText = text.toLowerCase();  // 'hello, world!'

strip()

The strip() method removes any leading (at the beginning) and trailing (at the end) whitespace characters from a string. For example:

const text = '   Hello, World!   ';
const strippedText = text.strip();  // 'Hello, World!'

replace()

The replace() method replaces a specified substring with another substring. For example:

const text = 'Hello, World!';
const replacedText = text.replace('Hello', 'Hi');  // 'Hi, World!'

split()

The split() method splits a string into a list of substrings based on a specified delimiter. For example:

const text = 'apple,banana,cherry';
const splitText = text.split(',');  // ['apple', 'banana', 'cherry']

Conclusion

String methods in Python provide powerful tools for manipulating strings. By using these methods, you can easily change the case of strings, strip whitespace, replace substrings, split strings into lists, and perform many other common string operations.
