Python Strings and their methods

With Code Implementation

In Python, a string is a sequence of characters enclosed in quotation marks (either single quotes or double quotes). Strings are one of the basic data types in Python, and they can be manipulated using various built-in methods.

Here is an overview of some common string methods in Python:

1. len() - returns the length of the string.

2. lower() - returns a copy of the string in lowercase.

3. upper() - returns a copy of the string in uppercase.

4. strip() - removes any leading and trailing whitespace characters from the string.

5. replace() - replaces all occurrences of a specified substring in the string with another substring.

6. split() - splits the string into a list of substrings based on a specified delimiter.

Summary :
These are just a few examples of the many string methods available in Python. By using these methods, you can manipulate and process strings in a variety of ways.
