The method find(substring) returns the index of the first occurrence of the substring in the string, or -1 if the substring is not found. This is the most direct and efficient way to determine whether a substring is present in a string. The other methods are used for different purposes; endswith(substring) checks if the string ends with the substring, replace(string, substring) replaces all occurrences of the substring with a new string, and startswith(substring) checks if the string starts with the substring.
