![]() With that said, let’s learn what a tuple is and how to write/use them. Like Python sets, lists and dictionaries, tuples are built-in data types, but faster to work with than those other choices. Although once you understand what this feature does, it’s rather simple to work with. A tuple is a single variable that can hold multiple items. We’ve already covered reading text from files, the Range function, data types, and numerous other concepts surrounding this user-friendly language.īut not every concept is as easy to grasp. So instead of writing a program, compiling it, and running it…you simply write it and run it.įor the most part, Python is quite simple to grasp. It also happens to be one of the best languages for beginners, because it’s not only so easy to learn, it doesn’t require complicated compilers, and, instead, uses an interpreter to run programs. After each iteration, don't forget to raise the index by 1.Python is a very powerful and flexible programming language. Determine the length of the tuple using the len() function, then begin at index 0 and loop through the tuple items using the indexes. Using a while loop, you can iterate through the list items. Example firstuple = ("apple", "banana", "cherry") ![]() Make a suitable iterable using the range() and len() functions. The items in the tuple can also be looped through by using their index numbers. Using a for loop, you can iterate through the items in the tuple. The string and integer are two of the tuple's four components. The output of the above example includes every element, from the first to the last. Example myTuple = ("Dehradun", 4, 29, 13) To get all the elements in the output, use the tuple variable without using any index operators. You don't need to use the index operator to get all the elements. There is another straightforward method to retrieve all elements of the variable in addition to the methods mentioned above. The output consists of a single item, which in Python is the last item of the tuple. The tuple from the above example has four elements. The final element, which is 13 in the example above, is present. Check and apply the example provided below to the last item in the tuple Example myTuple = ("Dehradun", 4, 29, 13) It locates the final items in the variable and prints them in the output. Passing -1 as an argument to an index operator is required, if you want to find the last item in the tuple. The first item in the variable, which has four components, is printed as "Dehradun." The output does not include round brackets or parenthesis when printing items. The output from the above example only contains the first element. ![]() To obtain the first element from the tuple, use the example below. The first element in a Python tuple starts with the index zero(0) and is located there. The index operator requires a single argument, which must be zero (0). Using the index operator will allow you to retrieve the first element of the tuple. Heterogeneous − We can create tuples with different type of values. Unchangeable − Tuples are immutable, which means that once we create a tuple, we cannot change, add, or remove any of its components. Ordered − When we say that a tuple is ordered, we are referring to the fact that the items are in a specific order that won’t change. Example firstuple = ("apple", "banana", "cherry", "apple", "cherry")įollowing is the output of the above code – ('apple', 'banana', 'cherry', 'apple', 'cherry') The first item in a triple has an index of, the second has an index of, and so on. Tuple items − Duplicate values are permitted for triple items which are ordered and immutable. firstuple = ("apple", "banana", "Cherry")įollowing are the points to be noted while working with tuples. Exampleįollowing is an example of creating a tuple. Round brackets are used when writing tuples. Unchangeable and ordered collections are called tuples. One of python’s four built-in data types for storing data collections is the tuple. Tuples allow for the storage of several things in a single variable. We will go over the syntax for accessing these elements and will provide examples of how to do so. In this article, we will be discussing how to extract the first and last elements from a tuple in Python. ![]() Tuples are an important data type in Python and are often used to store a fixed set of elements. ![]()
