A Complete Guide To Python Tuple
As per the Regional Research Reports, the global Python market is projected to achieve a staggering USD 17.88 billion by 2033. Python is a popular high-level programming language, and it is widely used in developing web applications and graphical user interfaces (GUIs).
Python continues to thrive. This article will guide you through a crucial data structure in Python, known as Tuples. It covers topics such as defining tuples in Python, providing examples of Python tuples, and explaining how to create tuples in Python, among other aspects.
Define Tuple In Python
A tuple is a collection of objects that are separated by commas. Tuples can easily store several items in a single variable. In fact, it is one of the four built-in data types present in Python. Apart from tuples, the other three data types are:
- List
- Set
- Dictionary
All these three data set types have different usage and qualities. Regarding the tuple, it is unchangeable. Tuple syntax in Python:
tup1 = ('biology', 'physics', 1897, 2022);
tup2 = (11, 12, 13, 14, 15 );
tup3 = "e", "f", "g", "h";
Characteristics Of Tuple
Python has a large scope, to be ahead of the game, you can always opt for a Python course that will help you have an in-depth knowledge of this programming language and help you excel in your career. Tuple has the following characteristics:
- Tuples work as containers, which means you can store the data in them.
- Since tuples are ordered, the elements present have a specific position, or the position has meaning.
- Since tuples are iterable, you can also use them in a loop.
- Tuples are immutable, so once created, you cannot change them.
- Tuples are heterogenous as they contain different data types.
How To Create A Tuple In Python
You can create a Python tuple with the help of comma-separated elements inside the parenthesis ().
t1 = (5, 6, 7, 8)
t2 = ("Make", "Use", "Of")
t3 = (6.7, 7.8, 4.5, 7.9)
All the elements are ordered and immutable, so you can easily duplicate the value and get any number of elements. You can create an empty tuple, too; remember, the element can be any data type, be it a tuple, string, float, integer, etc.
- Create An Empty Tuple: If you want to create an empty tuple, you must use the empty opening and closing parentheses.
emptyTuple = ()
- Create a Tuple With a Single Element: If you want to create a tuple with only a single element, you must place the comma after the element. This will let Python recognize the element as a tuple.
# t1 is a tuple
t1 = ( 3.54, )
print( type(t1) )
# prints
<class 'tuple'>
- Create a Tuple With Several Data Types: As you know, you can use any data type as the element of the tuple. This lets the tuple be versatile. Elements of the tuple can be of any data type.
tup1 = ( 'Make use of, True, 9.3, 65, [2, 3, 4] )
print( tup1 )
# prints
('Make use of', True, 9.3, 65, [2, 3, 4])
- Create a Tuple Using Tuple () Constructor: You can use the tuple() Constructor to create a tuple. With the help of tuple() Constructor, you can easily convert the sequences such as dictionary/list into a tuple.
tup1 = tuple( (2, 3, 4) )
print( tup1 )
# prints
(1, 2, 3)
- Create a Nested Tuple: You can nest one tuple into another.
tup1 = (2, 3, 4)
tup2 = ( 'Hie', tup1, 45 )
print( tup2 )
# prints
('Hie', (2, 3, 4), 45)
How To Access Items In Python Tuple
In tuples, you can access the items with the help of indexing. You can specify the value of the index, and then the item stored at that value will be returned.
The accessing methods with the Python tuple example are shown below:
- Indexing: Indexing is an efficient method for accessing information within a data structure. In Python, it’s essential to understand that various data types, including strings and lists, support this technique for retrieving data.
To understand it better, here is a Python tuple example:
Step 1: Suppose you have a tuple that has five natural numbers (1,2,3,4,5).
Step 2: The next step is indexing. When the indexing starts, it will begin at zero, where the value 1 is stored.
Step 3: And it will continue until the last natural number, 5. So, the value of the index at five is 4. Look at the syntax below:
>>>tup1 = (1, 2, 3, 4, 5)
# for accessing the first element of the tuple
>>>tup1[0]
1
# accessing the fourth element of the tuple
>>>tup1[3]
5
- Negative Indexing: In Python, you can also use negative indexing to access the elements in the tuple or the elements present in other data types that support indexing.
- Slicing: Another way of accessing the elements is via slicing. The slicing operator ‘:’ is used to get to the range of elements in the tuple or the elements present in other data types that support indexing.
Difference Between List And Tuple
Although a Python tuple and a list are similar, these two have some significant differences. For example, in Tuple, you cannot change the elements inside the brackets after you have assigned them.
Here are some of the essential differences between a list and a tuple:
| Tuple | List |
| Tuple consists of heterogeneous data types. | The list consists of homogenous data types. |
| It is Immutable in nature. | It is mutable in nature. |
| Immutable elements work as a key for a dictionary. | There are no immutable elements present in a list. |
| Data is write-protected. | There is no guarantee of data being write-protected. |
Tuple Methods In Python
There are two tuples methods in Python: Count () and Index()
- Count (): COunt () returns the times a particular value occurs in the tuple.
Count()
Tuple example in Python for the count () method is:
tuple.count(element)
numbers = (2, 3, 4, 2, 5,2 )
# count the number of 2's in the tuple
count = numbers.count(2)
print('The count of 2 is:', count)
Output
The count of 2 is: 3
The count of 8 is: 0
- Index(): It searches the tuples for a particular value, and then it returns the value to the position where it was found.
Index()
tuple syntax in Python for Index () method is
tuple.index(element, start, end)
There are three parameters:
Element: It is the element that is required to be search
Start (Optional): It is the starting Index. From here, the search is started. The starting Index from where the search is started
End (Optional): It is the ending Index where the search ends.
Example of index() tuple:
# tuple containing vowels
vowels = ('a', 'e', 'i', 'o', 'u')
# index of 'i' in vowels
index = vowels.index('i')
print(index)
# Output: 1
- In the above example, we have used the Index () method to find the Index of the specified elements. For that, we have used the vowels tuple.
The element “i” appears in index 1 in the vowels tuple. That is why the output returns 1.
Advantages Of Using Python Tuple
Python lets the developer put their focus on developing the core functionality of the software or application that they are designing. The syntax is simple, which makes programming easy; hence developers are showing more interest in Python.
The major advantages of Python tuple are:
- Tuples in Python are one of the easiest and simple data structures that can be used for grouping arbitrary objects. The features, such as aspect-oriented programming, object-oriented, and structured programming and tuples, make Python an accessible language.
- Python’s memory manager has several components that help in making dynamic memory management feasible.
- When it comes to a programming language, one of the vital factors is readability. Python provides developers with the English coding language. The punctuation is replaced with English keywords. So one does not have to write additional code. Since this programming language is readable, it makes it easy to debug, update and maintain the code.
- Coding tuples and using the tuple unpacking ensures that the code has become more readable and there are several variables that are assigned simultaneously in one line of code.
Conclusion
Python is gaining popularity in several industrial and academic settings. Mostly Python is used for developing software, websites, data visualization, analysis, etc. Python tuples are a convenient way to construct and access the elements in the programming. career.
