How is access to tuple elements performed using syntax in the programming language?

In Python, access to tuple elements is done by index using square brackets []. Indexing starts at zero.

Example:

my_tuple = (10, 20, 30, 40)
print(my_tuple[0])  # Outputs 10
print(my_tuple[2])  # Outputs 30

Negative indices can also be used to access elements from the end:

print(my_tuple[-1])  # Outputs 40
print(my_tuple[-3])  # Outputs 20

It is important to remember that tuples are immutable, so elements cannot be changed by index.
