  Immutability of Tuples Key Property: Tuples are immutable.  You cannot modify, add, or remove elements after creating a tuple.  Example: Attempting to modify a tuple: my_tuple = (1, 2, 3) my_tuple[0] = 5 # Error: TypeError: 'tuple' object does not support item assignment

  Nested Tuples Tuples cancontain other tuples (nested structure). nested_tuple = (1, (2, 3), (4, 5, 6)) print(nested_tuple[1]) # Output: (2, 3) print(nested_tuple[1][0]) # Output: 2

  Tuple Methods  Indexing& Counting Methods  tuple.index(value)  Returns the index of the first occurrence of value.  my_tuple = (10, 20, 30, 10)  print(my_tuple.index(10)) # Output: 0  tuple.count(value)  Returns the count of the number of times value appears.  print(my_tuple.count(10)) # Output: 2

  Tuple Use Cases UseCases of Tuples: 1.Data Integrity: Use tuples when you want to ensure data cannot be changed. 2.Dictionary Keys: Tuples can be used as keys in dictionaries because they are immutable. 3.Fixed Collections: Group related items that should remain constant, like coordinates (x, y).

  When to UseTuples?  When you need data that shouldn’t be changed.  When memory optimization is critical.  When using elements as dictionary keys.  When you're dealing with a collection of heterogenous data.

  Conclusion  Summary:  Tuplesare ordered, immutable collections in Python.  They are memory efficient and provide faster operations compared to lists.  Use them when you need read-only collections of data.
