What is the difference between string methods in Python?

What is the difference between string methods in Python?

In Python, string methods are functions that perform operations on string objects. For example, 'str.upper()' converts a string to uppercase, while 'str.lower()' converts it to lowercase.

Can you give me examples of some common string methods?

Sure! Some common string methods include:

1. str.strip() - removes whitespace from the beginning and end.
2. str.replace(old, new) - replaces occurrences of a substring.
3. str.split(separator) - splits a string into a list based on a separator.

What does the str.find() method do?

The str.find(substring) method returns the lowest index of the substring if found in the string. If not found, it returns -1.

Are there any string methods that modify the original string?

No, string methods in Python return new strings and do not modify the original string, as strings are immutable.
