You can update single or multiple elements of lists by giving the slice on the lefthand side of the assignment operator, and you can add elements in a list with the append( ) method. Following is a simple example:
!/user/bin/python
listl = [‘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.
When the above code is **, it produces the following result:**
Value available at index 2 :
1997
New value available at index 2 :
2001
