Program:

# Declaring a list with integer and string elements
list = [10, 20, 30, "New Delhi", "Mumbai"]

# printing list
print "List elements are: ", list

# adding elements 
list.append (40)
list.append (50)
list.append ("Chennai")

# printing list after adding elements
print "List elements: ", list

# removing elements
list.pop () ;
# printing list
print "List elements: ", list
# removing elements
list.pop () ;
# printing list
print "List elements: ", list

Output

    List elements are:  [10, 20, 30, 'New Delhi', 'Mumbai']
    List elements:  [10, 20, 30, 'New Delhi', 'Mumbai', 40, 50, 'Chennai']
