Tuple

1. A Tuple is a collection of Python objects separated by commas.

2. In someways a tuple is similar to a list in terms of indexing, nested objects and repetition but a tuple is immutable unlike lists which are mutable.

Example - 1:

# Creating non-empty tuples 
  
# One way of creation 
tup = 'python', 'gyansetu'
print(tup) 
  
# Another for doing the same 
tup = ('python', 'gyansetu') 
print(tup) 

('python', 'gyansetu')

('python', 'gyansetu')

Example - 2:

t = ( 5,6,7)
print(t)
print(type(t))

(5, 6, 7)

<class 'tuple'>

Example - 3:

#code to test that tuples are immutable 
  
tuple1 = (0, 1, 2, 3) 
tuple1[0] = 4
print(tuple1) 

TypeError Traceback (most recent call last)

in () 2 3 tuple1 = (0, 1, 2, 3) ----> 4 tuple1[0] = 4 5 print(tuple1)

TypeError: 'tuple' object does not support item assignment

Example - 4:

l1 = [ 1,2,3]
l2 = [4,5,6]
t1 = ('hi','hello')
t2 = ('bye',1,2,3)
t3 = t1 + t2 #add both the tuples
print(t1)
print(t2)
print(t3)
l3 = l1+l2
print(l1)
print(l2)
print(l3)

('hi', 'hello')

('bye', 1, 2, 3)

('hi', 'hello', 'bye', 1, 2, 3)

[1, 2, 3]

[4, 5, 6]

[1, 2, 3, 4, 5, 6]

Example - 5:

# code to test slicing 
  
tuple1 = (0 ,1, 2, 3) 
print(tuple1[1:]) 
print(tuple1[::-1]) 
print(tuple1[2:4])

(1, 2, 3)

(3, 2, 1, 0)

(2, 3)

Example - 6:

# Code for printing the length of a tuple 
  
tuple2 = ('python', 'awesome') 
print(len(tuple2)) 

2

Example - 7:

# Code for converting a list and a string into a tuple 
  
list1 = [0, 1, 2] 
print(tuple(list1)) 
print(tuple(('python'))) # string 'python' 

(0, 1, 2)

('p', 'y', 't', 'h', 'o', 'n')
