Python Tuples

Tuples in python are collection of objects which is separated by comma (,) , tuples are similar to list except the fact that tuples are immutable (means once defined it cannot be changed) collection of objects or data is start with ( and ends with ) .

Example 1 :

tuple1 = ('edu','1','techs')
tuple2 = ('edu-techs',1,2,3)
print(tuple1)
print(tuple2)

Output :

('edu', '1', 'techs')
('edu-techs', 1, 2, 3)

Example 2 :

# Tuple immutability
tuple1[2] = '123'
print(tuple1)

Output :

Traceback (most recent call last):
  File "e0eaddff843a8695575daec34506f126.py", line 3, in
    tuple1[2]='123'
TypeError: 'tuple' object does not support item assignment

Slicing Python Tuples :

Slicing in tuples is totally similar to slicing in python List .

tuple3 = (0 ,1, 2, 3)
print(tuple3[1:])
print(tuple3[::-1])
print(tuple3[2:4])

Output :

(1, 2, 3)
(3, 2, 1, 0)
(2, 3)

Converting List or String to Tuple :

list1 = [0, 1, 2]
print(tuple(list1)) # list to tuple
print(tuple('python')) # string 'python' to tuple

Output :

(0, 1, 2)
('p', 'y', 't', 'h', 'o', 'n')

Operations That cannot be work in Python Tuples :

• We cannot update a tuple which is already defined or created.
• Once a tuple is defined it cannot be deleted.
• we cannot increase length of a tuple which is already defined or created.
• We cannot append into a already defined tuple.
