Python -Update Tuples
Tuples are unchangeable, meaning that you cannot change, add, or remove items once the tuple is created.
But there are some workarounds.
Change Tuple Values
Once a tuple is created, you cannot change its values. Tuples areunchangeable, orimmutable as it also is called.
But there is a workaround. You can convert the tuple into a list, change the list, and convert the list back into a tuple.
Example
Convert the tuple into a list to be able to change it:
y = list(x)
y[1] = "kiwi"
x = tuple(y)
print(x)
Add Items
Since tuples are immutable, they do not have a built-inappend() method, but there are other ways to add items to a tuple.
1.Convert into a list: Just like the workaround for changinga tuple, you can convert it into a list, add your item(s), and convert it back into a tuple.
Example
Convert the tuple into a list, add "orange", and convert it back into a tuple:
y = list(thistuple)
y.append("orange")
thistuple = tuple(y)
2.Add tuple to a tuple. You are allowed to add tuples to tuples, so if you want to add one item, (or many), create a new tuple with the item(s), and add it to the existing tuple:
Example
Create a new tuple with the value "orange", and add that tuple:
y = ("orange",)
thistuple += y
print(thistuple)
Note: When creating a tuple with only one item, remember to include a comma after the item, otherwise it will not be identified as a tuple.
Remove Items
Note: You cannot remove items in a tuple.
Tuples areunchangeable, so you cannot remove items from it, but you can use the same workaround as we used for changing and adding tuple items:
Example
Convert the tuple into a list, remove "apple", and convert it back into a tuple:
y = list(thistuple)
y.remove("apple")
thistuple = tuple(y)
Or you can delete the tuple completely:
Example
Thedel keyword can delete the tuple completely:
delthistuple
print(thistuple) #this will raise an error because the tuple no longer exists
