Question

What is slicing?

Answer 1

String slicing:
A slice is a substring of the main string. A substring can be taken from the original string by using [ ] operator and index or subscript values. Thus, [ ] is also known as the slicing operator. Using the slice operator, we can slice one or more substrings from the main string.

The general format of slice operation:
str[start:end]
Where start is the beginning index and end is the last index value of a character in the string. Python takes the end value less than one from the actual index specified. For example, if you want to slice the first 4 characters from a string, you have to specify it as 0 to 5. Because python considers only the end value as n – 1.

Example:

slice a single character from a string

>>> str1=”THIRUKKURAL”
>>> print (str1[0])
