When we look at the basic building blocks of data in Python, tuples are pretty interesting. They are different from other types, like lists and arrays. Let’s take a closer look at what makes tuples special!
One big thing about tuples is that they are immutable. This just means that once you create a tuple, you can’t change what’s inside it. For example:
my_tuple = (1, 2, 3)
If you try to change it, like this:
my_tuple[0] = 5
You will get an error! This rule can be helpful when you want to keep your data the same while your program runs. It makes your code safer and can help it run faster.
Tuples are made using parentheses (), which makes them easy to spot:
my_tuple = (1, 'apple', 3.14)
You can also create a tuple with just one item, but remember to put a comma after it:
single_element_tuple = (42,)
Tuples work great in some situations, such as:
def calculate():
return 42, "Success"
result, status = calculate()
Because tuples don’t change, they are usually faster than lists. If you know you won’t need to change a collection of items, it’s better to use a tuple instead of a list.
In short, tuples are special because they don’t change, they are easy to create, and they run faster. They are great for keeping constant values or sending back multiple results from functions. Knowing these benefits can help you pick the right data structure for your coding projects!
