• Single Character Indexing : Slice a single character from the string. By giving an index from the string.

• Multiple Character Indexing : Slice multiple character from the string. By giving the start index and last index, separated by colon.

• Negative Indexing : Slice characters with the help of negative indexing. By giving the negative start index and last index, separated by the colon.

• Skip Indexing : Slicing the string by skip the characters. By giving the start index, last index and skip index, separated by the colon.

Python string methods are used to manipulate the strings. Following are useful built-in methods :

•  len(string)  : Used to find the length of the string.

•  string.capitalize()  : Used to convert the first character of the string into upper case.

•  string.count()  : Used to count the occurrence of a specific character in the string.

•  string.endswith()  : Used to find whether the string ends with the given character or not.

•  string.find()  : Used to find the position of the given character in the string.

•  string.replace()  : Used to replace specified character from the given value.
