Tuple

Basic Of Tuple

  • A tuple is a sequence of immutable Python objects. Tuples are sequences, just like lists.
  • A tuple is a collection that is ordered and unchangeable. In Python, tuples are written with round brackets.
  • Tuples are used for grouping data. Each element or value that is inside of a tuple is called an item.

Syntax:

tuplename=(elem1,elem2,elem3...)

Example:

color=("red","blue","green")
print(color)

Output:

('red', 'blue', 'green')
  • Create A blank Tuple
blanktuple=() 
#you can also use 
blanktuple=tuple()

#Print the type of above object
print(type(blanktuple))

Output:

<tuple class>

To write a tuple containing a single value you have to include a comma, even though there is only one value

Example:

tupl1=(4,) 
print(tupl1)

Output:

(4,)
  • Create A tuple with 7 element
elements=(1,2,3,4,5,6,7) 
#printing the Element
print(elements)

Output:

(1,2,3,4,5,6,7)

Access Tuple Items

  • As an ordered sequence of elements, each item in a tuple can be called individually, through indexing.
  • Each item corresponds to an index number, which is an integer value, starting with the index number 0.
  • You can access tuple items by referring to the index number, inside square brackets

Syntax:

tuplenmae[index]

Example:

mytuple=(2,4,5,67) 
print("Tuple Element")
print(mytuple)

#get 5 element 
res=mytuple [2]
print("Element at index 2")
print(res)
#Result:5

Output:

Tuple Element
(2, 4, 5, 67)
Element at index 2
5

Access Multiple elements from a tuple

We can use indexing to call out a few items from the tuple. Slices allow us to call multiple values by creating a range of index numbers separated by a colon [x:y].

we can use slicing to accessing elements from the tuple.

Synatx:

tuplename[startpostion:endposition]

Example:

mytuple=(1,3,4,5,6,7,8,9) 
res=mytuple[2:7]
print(res)

Output:

(4,5,6,7,8,9)

Extended slicing

  • The syntax for this construction is tuple[x:y:z], with z referring to stride. Let’s make a larger list, then slice it,

Example:

numbers = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) 
print(numbers[1:11:2])

Output:

(1, 3, 5, 7, 9)
  • We can omit the first two parameters and use stride alone as a parameter with the syntax tuple[::z]

Example:

numbers = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) 
print(numbers[::3])

Output:

(0, 3, 6, 9, 12)
