Question

What is the use of len() and sort() functions of LIST data type with

suitable example?​

Answer 1

Answer:

Sort() is used to sort the list in ascending order and Len() returns the length of the list, basically len() returns how many elements are there in a list but it gives in int format by counting the elements of the list.

Answer 2

Python provides the sort( ) method to sort the elements of a list.

Let x be a list [2, 6, 1, 4, 7, 3, 5], then,

This method can be used as:

x.sort( )

This will sort the list 'x' in ascending order.

[1, 2, 3, 4, 5, 6, 7]

If we want to sort the elements of the list into descending order, then we can mention 'reverse=True' in the sort method as:

x.sort(reverse=True)

This will sort the list 'x' into descending order.

[7, 6, 5, 4, 3, 2, 1]

To know the length of a list, we can use the len( ) function.

This function gives the number of elements in the list.

This function can be used as:

len(x)

This will return the length as:
