[0, 2, 11, 20]

Example 2:

number=[11, 2, 20, 0]

[ 20, 11, 2, 0]   

                                                   #TUPLES ()


fruits=['apple','orange','cherry']
number=[11, 2, 20, 0]
print(fruits+number)                     #A Tuples is a collection  which is order and  UNCHANGEABLE.
output:
['apple','orange','cherry', 11, 2, 20, 0]

                                                   #SET{}
