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.
#!/usr/bin/python list = ['physics', 'chemistry', 1997, 2000]; print "Value available at index 2 : " print list list = 2001; print "New value available at index 2 : " print list
Note − append() method is discussed in subsequent section.
When the above code is executed, it produces the following result −
Value available at index 2 : 1997 New value available at index 2 : 2001
