Demystifying Python Tuples
At its core, a tuple in Python is a collection of items that are ordered and immutable. This means that unlike other data types like lists, you can’t make any changes – such as adding or removing items – to a tuple once it’s created. You may find yourself wondering,
So, why should I learn about Python tuples?
Good question! Tuples can be compared to ‘read-only’ lists. However, they come with their own special powers which make them ideal for specific situations. For example:
- Tuples being immutable make them safe for storing data that shouldn’t be changed.
- They are faster than lists, which can be a boon when dealing with large datasets.
- Python’s ability to assign multiple variables in one line with tuples can lead to cleaner, more intuitive code.
Understanding how to use tuples effectively can be a great asset to your Python programming toolkit.

Creating Tuples in Python
Now that we’ve covered what tuples are, let’s head into creating our own! This is usually done by placing all items, separated by commas, inside parentheses.
zenTuple1 = ("Zenva", "Academy", "<a class="wpil_keyword_link" href="https://gamedevacademy.org/learn-to-code-what-is-coding/" target="_blank" rel="noopener" title="coding" data-wpil-keyword-link="linked">coding</a>")
print(zenTuple1)If you run the above code, you’ll see “Zenva”, “Academy”, “coding” returned. Creating an empty tuple is done the same way, simply without any items within the parentheses.
emptyTuple = () print(emptyTuple)
Accessing Tuple Items
A powerful aspect of tuples is the ability to access any item by referring to its index number. Just remember that Python starts counting from zero!
print(zenTuple1[1]) # This will return "Academy"
Python also allows you to use negative indexing, which means starting from the end -1 refers to the last item, -2 refers to the second from last, and so on.
print(zenTuple1[-1]) # This will return "coding"
Looping through a Tuple
With Python, you can loop through a tuple to examine each item. This is done using a ‘for’ loop.
for i in zenTuple1: print(i)
Running the above code will print out each item in the tuple one-by-one: “Zenva”, “Academy”, “coding”.
Stay tuned for the last part of this tutorial where we’ll delve into more complex operations with tuples like tuple concatenation, repetition, and slicing.
Tuple Concatenation and Repetition
Though tuples are immutable, you can take entire tuples and join or repeat them to form new ones. This doesn’t alter the original tuples, but instead creates a new one from your operations.
Tuple Concatentation
Let’s say we have two separate tuples which we want to merge into a single tuple. We can use the ‘+’ operator to achieve this.
tuple1 = ("Zenva", "Academy")
tuple2 = ("<a class="wpil_keyword_link" href="https://gamedevacademy.org/what-is-unity/" target="_blank" rel="noopener" title="Unity" data-wpil-keyword-link="linked">Unity</a>", "Courses")
mergedTuple = tuple1 + tuple2
print(mergedTuple) # This will return ('Zenva', 'Academy', 'Unity', 'Courses')Tuple Repetition
Similarly, if we want to repeat items within a tuple a certain number of times, we can use the ‘*’ operator.
repeatTuple = tuple1 * 2
print(repeatTuple) # This will return ('Zenva', 'Academy', 'Zenva', 'Academy')Tuple Item Check and Length
Python also allows for quick checks to see if a specific item exists in a tuple, and to find out the length of the tuple.
Checking if an Item Exists
To check if a specific item exists within a tuple, you can use the ‘in’ keyword.
if "Zenva" in tuple1:
print("Yes, 'Zenva' is in the tuple")Finding the Length of a Tuple
To find out how many items a tuple has, use the ‘len()’ method.
print(len(tuple1)) # This will return 2
Tuple Slicing
Finally, let’s talk about tuple slicing. It means getting a range of items from a tuple, specified by a start and an end index.
print(mergedTuple[1:3]) # This will return ('Academy', 'Unity')The above operation retrieves the second and third items from the tuple (remember, Python’s indexing starts from 0).
