Manipulating Tuples

Tuples are immutable, hence if you want to add, remove or change tuple items, then first you must convert the tuple to a list. Then perform operation on that list and convert it back to tuple.

Example:

countries = ("Spain", "Italy", "India", "England", "Germany")
temp = list(countries)
temp.append("Russia")       #add item 
temp.pop(3)                 #remove item
temp[2] = "Finland"         #change item
countries = tuple(temp)
print(countries)

Output:

('Spain', 'Italy', 'Finland', 'Germany', 'Russia')

 

Thus, we convert the tuple to a list, manipulate items of the list using list methods, then convert list back to a tuple.

 

However, we can directly concatenate two tuples instead of converting them to list and back.

Example:

countries = ("Pakistan", "Afghanistan", "Bangladesh", "ShriLanka")
countries2 = ("Vietnam", "India", "China")
southEastAsia = countries + countries2
print(southEastAsia)

Output:

('Pakistan', 'Afghanistan', 'Bangladesh', 'ShriLanka', 'Vietnam', 'India', 'China')
