Read Tuple and Array Through Text File

Tuple is a collection of Python objects much like a list. The sequence of values stored in a tuple can be of any type, and they are indexed by integers.

Values of a tuple are syntactically separated by 'commas'. Although it is not necessary, it is more common to ascertain a tuple by closing the sequence of values in parentheses. This helps in agreement the Python tuples more than easily.

Creating a Tuple

In Python, tuples are created by placing a sequence of values separated by 'comma' with or without the use of parentheses for grouping the data sequence.

Note: Creation of Python tuple without the use of parentheses is known as Tuple Packing.

Python program to demonstrate the addition of elements in a Tuple.

Python3

Tuple1 = ()

impress ( "Initial empty Tuple: " )

print (Tuple1)

Tuple1 = ( 'Geeks' , 'For' )

print ( "\nTuple with the use of String: " )

print (Tuple1)

list1 = [ one , 2 , iv , 5 , 6 ]

print ( "\nTuple using Listing: " )

print ( tuple (list1))

Tuple1 = tuple ( 'Geeks' )

impress ( "\nTuple with the use of function: " )

impress (Tuple1)

Output:

Initial empty Tuple:  ()  Tuple with the use of Cord:  ('Geeks', 'For')  Tuple using Listing:  (1, 2, four, 5, 6)  Tuple with the use of office:  ('Chiliad', 'due east', 'east', 'one thousand', 's')        

Creating a Tuple with Mixed Datatypes.

Tuples can incorporate whatsoever number of elements and of whatsoever datatype (similar strings, integers, list, etc.). Tuples can also be created with a single element, merely it is a bit tricky. Having one element in the parentheses is not sufficient, at that place must be a trailing 'comma' to make information technology a tuple.

Python3

Tuple1 = ( 5 , 'Welcome' , 7 , 'Geeks' )

print ( "\nTuple with Mixed Datatypes: " )

print (Tuple1)

Tuple1 = ( 0 , i , ii , three )

Tuple2 = ( 'python' , 'geek' )

Tuple3 = (Tuple1, Tuple2)

print ( "\nTuple with nested tuples: " )

print (Tuple3)

Tuple1 = ( 'Geeks' ,) * iii

impress ( "\nTuple with repetition: " )

impress (Tuple1)

Tuple1 = ( 'Geeks' )

northward = five

print ( "\nTuple with a loop" )

for i in range ( int (n)):

Tuple1 = (Tuple1,)

print (Tuple1)

Output:

Tuple with Mixed Datatypes:  (5, 'Welcome', vii, 'Geeks')  Tuple with nested tuples:  ((0, ane, two, 3), ('python', 'geek'))  Tuple with repetition:  ('Geeks', 'Geeks', 'Geeks')  Tuple with a loop ('Geeks',) (('Geeks',),) ((('Geeks',),),) (((('Geeks',),),),) ((((('Geeks',),),),),)

Accessing of Tuples

Tuples are immutable, and normally, they comprise a sequence of heterogeneous elements that are accessed via unpacking or indexing (or fifty-fifty by attribute in the case of named tuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

Note: In unpacking of tuple number of variables on the left-hand side should be equal to a number of values in given tuple a.

Python3

Tuple1 = tuple ( "Geeks" )

impress ( "\nFirst element of Tuple: " )

print (Tuple1[ 0 ])

Tuple1 = ( "Geeks" , "For" , "Geeks" )

a, b, c = Tuple1

impress ( "\nValues after unpacking: " )

impress (a)

print (b)

print (c)

Output:

First element of Tuple:  G  Values after unpacking:  Geeks For Geeks

Concatenation of Tuples

Concatenation of tuple is the process of joining two or more than Tuples. Concatenation is washed by the use of '+' operator. Concatenation of tuples is washed always from the end of the original tuple. Other arithmetic operations do not apply on Tuples.

Annotation- Only the aforementioned datatypes can be combined with concatenation, an fault arises if a list and a tuple are combined.

Python3

Tuple1 = ( 0 , 1 , two , 3 )

Tuple2 = ( 'Geeks' , 'For' , 'Geeks' )

Tuple3 = Tuple1 + Tuple2

print ( "Tuple 1: " )

print (Tuple1)

print ( "\nTuple2: " )

print (Tuple2)

print ( "\nTuples after Concatenation: " )

print (Tuple3)

Output:

Tuple ane:  (0, 1, 2, 3)  Tuple2:  ('Geeks', 'For', 'Geeks')  Tuples after Concatenation:  (0, 1, 2, 3, 'Geeks', 'For', 'Geeks')

Slicing of Tuple

Slicing of a Tuple is done to fetch a specific range or slice of sub-elements from a Tuple. Slicing tin also be done to lists and arrays. Indexing in a list results to fetching a unmarried element whereas Slicing allows to fetch a set of elements.

Notation- Negative Increment values can also be used to reverse the sequence of Tuples.

Python3

Tuple1 = tuple ( 'GEEKSFORGEEKS' )

print ( "Removal of First Element: " )

print (Tuple1[ i :])

impress ( "\nTuple after sequence of Element is reversed: " )

print (Tuple1[:: - 1 ])

print ( "\nPrinting elements between Range iv-nine: " )

print (Tuple1[ iv : 9 ])

Output:

Removal of First Element:  ('E', 'E', 'K', 'S', 'F', 'O', 'R', 'Grand', 'Due east', 'East', 'Chiliad', 'S')  Tuple after sequence of Element is reversed:  ('S', 'K', 'E', 'E', 'Thou', 'R', 'O', 'F', 'S', 'Yard', 'E', 'E', 'Thousand')  Printing elements between Range 4-9:  ('S', 'F', 'O', 'R', 'Grand')

Deleting a Tuple

Tuples are immutable and hence they do not allow deletion of a function of it. The entire tuple gets deleted by the use of del() method.

Note- Press of Tuple after deletion results in an Fault.

Python

Tuple1 = ( 0 , 1 , 2 , 3 , four )

del Tuple1

impress (Tuple1)

Traceback (most contempo phone call concluding):
File "/home/efa50fd0709dec08434191f32275928a.py", line 7, in
impress(Tuple1)
NameError: name 'Tuple1' is not defined
