How do you create a tuple in Python?

• A. Using square brackets, e.g., my_tuple = []
• B. Using parentheses, e.g., my_tuple = ()
• C. Using braces, e.g., my_tuple = {}
• D. Using the tuple() function

Answer: (B)

To create a tuple in Python, the correct approach is to use parentheses. A tuple is defined as an immutable sequence type in Python, which means once it is created, it cannot be modified. By using parentheses, you define a tuple with items separated by commas. For example, my_tuple = (1, 2, 3) creates a tuple containing the integers 1, 2, and 3.

While the other options might seem related to creating collections, they actually refer to different data types. Using square brackets is how you create a list, which is a mutable collection. Using braces, on the other hand, creates a dictionary or a set, not a tuple. The tuple() function can also be used to create a tuple, but it does so by taking an iterable as an argument, thus it's not the most direct method to create a tuple from literals. Therefore, using parentheses is the primary and most straightforward method to define a tuple.
