Program Plan Intro

List slicing:

• • Slicing is a concept of selecting a range of elements from a list.
• • In Python, the expression that selects a subsection of a list is known as a slice.
• • A slice is a span of data that are taken from a list.
• • Normally, the slice expression has a start index and an end index for slicing.
• • In case if the end index is not provided, the python employs the length of the list as the end index.

Syntax:

In Python, the list slice statement without the end index can be expressed as follows:

listname[start:]

Explanation:

In the list slice syntax,

• • The “start” represents the index of the first data in the slice.
• • As the “end” index is not provided, Python employs the length of the list as the “end” index for the slice.
• • The list slice expression returns a list having a copy of data from index “start” up to the end of the list.
