Updating Lists in Python

You can update single or multiple elements of lists by giving the slice on the left-hand side of the assignment operator, and you can add to elements in a list with the append() method.

Example

 Live Demo

#!/usr/bin/python
list = ['physics', 'chemistry', 1997, 2000];
print "Value available at index 2 : "
print list[2]
list[2] = 2001;
print "New value available at index 2 : "
print list[2]

Note − append() method is discussed in subsequent section.

Output

When the above code is executed, it produces the following result −

Value available at index 2 :
1997
New value available at index 2 :
2001
