What is Python Tuple?
A tuple is an immutable ordered collection of elements in python enclosed with round brackets. The difference between tuples and lists is, a tuple is immutable means we can’t change tuple like a list. Lists are created with square brackets whereas tuples are created using parentheses.
How to Create a Tuple in Python?
Creating Tuples: To create a tuple we just have to put values with separated commas in round brackets. tup1 = (1,2,3,6,7,8); we can also put strings in tuple as follows: tup2 = (‘green’,’yellow’,’red’); Or we can put string with double inverted commas as : tup3 = “green”, “red”, “yellow”;
The empty tuple can be created with two parentheses having no value:
tup12 = ();
To create the tuple with a single value we have to write comma after that value although it is having no further values.
test = (15,);
Tuples start with index ‘0’. They can be manipulated by slicing, concatenating, and further processes like lists.
Repeating Tuples N times:
If we want to repeat the string ‘n’ times then we can do it as follows:
test=(‘stats’)*4
Output:
statsstatsstatsstats
It will give a continuous string as output.
If we want separate strings as output we have to write
Test= (‘stats’,)*4
Output:
(‘Stats’, ‘stats’, ‘stats’, ‘stats’)
Nested Tuples in Python
Nested tuples can be created as follows:
tup1 =(0, 4,8,12)
tup2 =(‘tuple’,’python’)
tuplnest =(tup1, tup2)
Print(tuplnest)
Output
(0, 4, 8, 12,’tuple’,’python’)
Immutable tuple in Python
Tuples are immutable, unlike lists. The elements in tuple can’t be edited.
Let’s see one example:
tup =(0, 1, ‘x’, ‘y’)
tuple1[0] =4
print(tup)
Output:
TypeError: ‘tuple’ object does not support item assignment.
Slicing Tuple in Python
In tuple slicing we can select the part of tuple as output , defined by starting and ending index as follows:
Ex)
test=(0,2,4,5,6,7,8,9,12)
print(test[1:])
Output: (2,4,5,6,7,8,9,12)
print(test[2:5])
Output: (4,5,6)
print(test[::-1])
Output: (12,9,8,7,6,5,4,2,1,0)
# We get output in exact reverse order.
print(test[-3:-1])
Output: (8,9)
Tuple Operations in Python
Deleting an item from Tuple:
We can delete the tuple by using the simply del command
tup1=( 0, 1,’a’,’b’)
deltup1
For confirmation, if we again print it will give an error
print(tuple3)
Output:
NameError: name ‘tup1’ is not defined
Length of Tuple:
To find the length of a tuple we use function len()
test=(1,2,5,’testing’,’length’,’of’,’tuple’)
print(len(test))
Output:
7
Use of count()
To find the count of a particular element in tuple this function is used.
test=(0,1,2,3,1,2,4,5,6,1,2,1)
print(test.count(1))
Output:
4
Use of index()
It returns index of specified element in tuple.
tup=(1,2,5,’a’,’python’,’tuple’)
print(tup.index(‘python’))
Output:
4
Converting a list to a Tuple
To convert a list into a tuple following method can be used
Ex) lis1=[1,2,4,’a’,’b’,’c’,’e’]
print(lis1)
Output:
(1,2,4,’a’,’b’,’c’,’e’)
If we take a single string and we applied the same method as above, we get a tuple having all separated characters.
Ex) print(tuple(‘python tuple’)
Output:
(‘p’, ‘y’, ‘t’, ‘h’, ‘o’, ‘n’, ‘ ‘, ‘t’, ‘u’, ‘p’, ‘l’, ‘e’, ‘s’)
Note: Here a space is also considered as character.
To compare tuples
For comparison purpose cmp(), min(), max() are used.
Let’s consider following tuples
tup1=(1,2,3,4,5)
tup2=(1,2,3,4,5,6)
To find minimum out of these tuples we use.
Ex) min(tup1,tup2)
Output:
(1,2,3,4,5)
To find the maximum out of these tuples we use.
Ex) max(tup1,tup2)
Output:
(1,2,3,4,5,6)
Checking for an element in Tuple
For this, we have to use the keyword ‘in’. It will give output in the form of True or False.
Ex) test=(1,2,3,’a’,’b’,’c’)
3 in test
Output:
True
Ex) test=(1,2,3,’a’,’b’,’c’)
‘x’ in test
Output:
False
