Python last element in tuple

Lesson 7: Python Tuples

Tuples are very similar to lists except a main difference: mutability. Tuples are immutable meaning they can not be changed unlike lists.

Otherwise, like lists, they can be consisted of different kind of elements and they have indexing meaning there is an order of elements inside them.

Index starts with 0 (zero) just like lists and negative index starts with -1, which refers to the last item in the tuple.

Used Where?

• .index(): used to show the index of an element
• .count(): used for counting how many elements there are in the list
• sum(): sums all the elements in the list
• min(): shows the element with lowest value in the list
• max(): shows the element with highest value in the list

Syntax do(s)

1) Tuples are constructed using parenthesis: ()

2) Elements inside your tuple should be separated with commas.

3) Syntax regarding data types need to be followed inside the tuples: strings in quotes and integers, booleans and float not in quotes.

Syntax don’t(s)

1) Elements inside your tuple should be separated with commas.

Function 1: tuple()

tuple() creates an empty tuple which can also be achieved by simply typing empty parenthesis: ().

Below is a tuple consisting of different types of elements.

Example 1

>>> p_tup = (“Oslo”, “Stockholm”, 44, True)
>>> print(p_tup )

Accessing Elements: List elements can be accessed with their index number in brackets.

p_tup = (“Oslo”, “Stockholm”, 44, True)

for instance to access the first element “Oslo” the correct syntax would be:

Let’s look at some examples.

Last element of the below tuple is a boolean with the value: True. We will access it inside the print function below.

Example 2

>>> p_tup = (“Oslo”, “Copenhagen”, 44, True)
>>> print( p_tup[3] )

And accessing the first element of the tuple.

Example 3

>>> p_tup = (“Oslo”, “Copenhagen”, 44, True)
>>> print( p_tup[0] )

Tips

1- Reverse Indexing: Similar to the lists elements in the tuple can also be accessed starting from the end which is reverse indexing. Reverse indexing starts with -1 which indicates the last element.

So, to access the last element of p_tup:
p_tup[-1] can be used and it would give you the last element of the tuple. p_tup[-2] would give you the second from the last, p_tup[-3] third from the last and so on.

2- Main difference of tuples from lists is that they are immutable which means they can’t be changed after they are created. Other than re-creating them you can’t append or remove elements the way you could for the lists.

So, it makes sense to use tuples where you know you won’t change your elements and otherwise it makes more sense to use lists.

How to get the last element from a tuple in Python?

Here we are to see how to get the last element from Tuple using Python as Programming Language. For this task, we need to understand the concept of Indexing.

Let’s understand this with an example.

i) Initially, a newborn child is 0 years old. After completion of 1 year, the age of the child will be 1 year and so on.
ii) Consider a building. Building starts with Ground (0) floor followed by 1st, 2nd floor and so on.

Similar is the concept of indexing. Indexing is accessing elements from sequence. Indexing in python is denoted with 0,1,2. or -1,-2. where 0 is the first index and -1 is the last index. In order to fetch element from sequence using Indexing “[ ]” is used.

Get the last element from Tuple

I) Using Negative Index

Step 1: Create a Tuple

The tuple is created on which Negative Indexing has to be implemented. A Tuple is capable of storing immutable objects. Immutable values refer to those values that can’t be changed.

Since we are learning how to display last element from tuple, first of all, create a tuple:

t = ("Codespeedy",3600,49.70,4,"Rani")

The negative index starts from where the sequence ends. Here, index value of -1 gives last element, -2 give second last element and so on. Python supports Negative Indexing. Hence, in order to access last element from tuple we use index value of -1.

Following is the pictorial representation of the entire process :

II) Using len(seq)

Step 1: Create a Tuple

t = ("Codespeedy",3600,49.70,4,"Rani")

Step 2: Use len(seq)

len() calculates the total length of tuple. Using this value we can the index of last element. Since indexing in python starts with 0, index of last element will be (length of tuple)-1.

print("Last element is:",t[len(t)-1])

Following is the pictorial representation of the entire process :

How to Find First and Last Element of Tuple in Python

In this tutorial, learn how to find first and last element of tuple in Python. The short answer is: use the index operator( [] ) to access the first element and the last element of the tuple using Python. You can get your single element of tuple with the methods given here.

In addition to this, you can also get elements from the first to the end of a given tuple using Python. You may also like to read how to create a tuple variable using Python

Get the First Element Of Tuple Using Python

If you want to get the first element of the tuple, you have to use the index operator( [] ). You have to pass zero ( 0 ) as the argument of the index operator.

The first element starts with the zero( 0 ) index and places inside the tuple in Python. See the example below and use it to get the first element from the tuple.

The above example gives the first element as the single element in the output. The variable contains 4 elements and prints “Bihar” which is the first item. The output prints items without the parenthesis or round brackets.

Python program to get first and last elements from a tuple

Tuples are an important data type in Python and are often used to store a fixed set of elements. In this article, we will be discussing how to extract the first and last elements from a tuple in Python. We will go over the syntax for accessing these elements and will provide examples of how to do so.

What is a Tuple in Python?

Tuples allow for the storage of several things in a single variable. One of python’s four built-in data types for storing data collections is the tuple.

Unchangeable and ordered collections are called tuples. Round brackets are used when writing tuples.

Example

Following is an example of creating a tuple.

firstuple = ("apple", "banana", "Cherry") print(firstuple)

Output

Features of a Python Tuple

Following are the points to be noted while working with tuples.

Tuple items − Duplicate values are permitted for triple items which are ordered and immutable. The first item in a triple has an index of [0], the second has an index of [1], and so on.

Example

firstuple = ("apple", "banana", "cherry", "apple", "cherry") print(firstuple)

Output

Following is the output of the above code –

('apple', 'banana', 'cherry', 'apple', 'cherry')

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.

Unchangeable − Tuples are immutable, which means that once we create a tuple, we cannot change, add, or remove any of its components.

Heterogeneous − We can create tuples with different type of values.

Example

tuple1 = ("abc", 34, True, 40, "male") print(tuple1)

Output

Finding the First Element of a Tuple

Using the index operator [] will allow you to retrieve the first element of the tuple. The index operator requires a single argument, which must be zero (0). The first element in a Python tuple starts with the index zero(0) and is located there. To obtain the first element from the tuple, use the example below.

Example

myTuple = ("Dehradun", 4, 29, 13) print(myTuple[0])

Output

The output from the above example only contains the first element. 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.

Finding the Last Element of a Tuple

Passing -1 as an argument to an index operator is required, if you want to find the last item in the tuple. It locates the final items in the variable and prints them in the output. Check and apply the example provided below to the last item in the tuple

Example

myTuple = ("Dehradun", 4, 29, 13) print(myTuple[-1])

Output

The final element, which is 13 in the example above, is present. The tuple from the above example has four elements. The output consists of a single item, which in Python is the last item of the tuple.

Printing all the Elements of a Tuple

There is another straightforward method to retrieve all elements of the variable in addition to the methods mentioned above. You don’t need to use the index operator to get all the elements. To get all the elements in the output, use the tuple variable without using any index operators.

Example

myTuple = ("Dehradun", 4, 29, 13); print(myTuple);

Output

The output of the above example includes every element, from the first to the last. The string and integer are two of the tuple’s four components.

Using for loop

Using a for loop, you can iterate through the items in the tuple.

Example

firstuple = ("apple", "banana", "cherry") for x in firstuple: print(x)

Output

Looping through index

The items in the tuple can also be looped through by using their index numbers. Make a suitable iterable using the range() and len() functions.

Example

firstuple = ("apple", "banana", "cherry") for i in range(len(firstuple)): print(firstuple[i])

Output

Using while loop

Using a while loop, you can iterate through the list items. Determine the length of the tuple using the len() function, then begin at index 0 and loop through the tuple items using the indexes. After each iteration, don’t forget to raise the index by 1.

Example

firstuple = ("apple", "banana", "cherry") i = 0 while i < len(firstuple): print(firstuple[i]) i = i + 1

Output
