You can calculate the length of a tuple in Python using the built-in len() function. Here are five examples demonstrating how to do this:

1. Example with a simple tuple:

tuple1 = (1, 2, 3, 4, 5)
length = len(tuple1)
print("Length of tuple1:", length)  # Output: Length of tuple1: 5

2. Example with an empty tuple:

empty_tuple = ()
length = len(empty_tuple)
print("Length of empty_tuple:", length)  # Output: Length of empty_tuple: 0

3. Example with a tuple containing strings:

tuple_strings = ('apple', 'banana', 'cherry', 'date')
length = len(tuple_strings)
print("Length of tuple_strings:", length)  # Output: Length of tuple_strings: 4

4. Example with a tuple containing nested tuples:

nested_tuple = ((1, 2), ('a', 'b', 'c'), (True, False))
length = len(nested_tuple)
print("Length of nested_tuple:", length)  # Output: Length of nested_tuple: 3

5. Example with a tuple containing mixed data types:

mixed_tuple = ('apple', 3.14, True, [1, 2, 3])
length = len(mixed_tuple)
print("Length of mixed_tuple:", length)  # Output: Length of mixed_tuple: 4

In each example, the len() function is used to calculate the length of the respective tuple, returning the number of elements it contains.
