Tuples Tuples in Python are similar to lists. A tuple is a sequence of comma separated numbers. A tuple can be decared as a sequence by enclosing or without enclosing them inside the () bracket and all elements are separated with commas. Elements in a tuple can be accessed via unpacking or indexing. Following are the two ways to declare the tuple in Python. a). Declaring and accessing tuple using indexing: >>>tup=(3,4,5,6,7) Or >>> tup=3,4,5,6,7 >>>tup1 (3,4,5,6,7) >>>tup[2] 5 >>>tup(3) 6 Since the tuple is immutable, A tuple does not have the append () or insert () method, nor can it be assigned to another element. >>>tup1=(3,4,5,6,7) >>>tup1[0]= 2 will give an error. TypeError: 'tuple' object does not support item assignment Because a tuple is unchangeable, the code is more secure. Therefore,
