Question 7+1-0Tag to RevisitHow can you access the first element of a tuple named my_tuple?Answer areamy_tuple[first]my_tuple[0]my_tuple[1]my_tuple[-1]

Break Down the Problem

1. Identify the Data Structure: We have a tuple called my_tuple.
2. Understanding Tuple Indexing: Tuples in Python are indexed, starting from 0 for the first element.

Relevant Concepts

1. Indexing in Python: The first element of any sequence (like lists, tuples, etc.) in Python can be accessed using index 0.
2. Negative Indexing: In Python, negative indexing starts from the end of the tuple, where -1 refers to the last element.

Analysis and Detail

1. Analyzing the options provided:
   • my_tuple[first]: This is incorrect because first is not defined as an index number; it should be an integer.
   • my_tuple[0]: This is correct as it accesses the first element of the tuple, which is indexed at 0.
   • my_tuple[1]: This accesses the second element of the tuple, which is incorrect if we want the first element.
   • my_tuple[-1]: This accesses the last element of the tuple, which is also incorrect for retrieving the first element.

Verify and Summarize

The correct way to access the first element of the tuple my_tuple is by using the index 0.

Final Answer

The correct answer is my_tuple[0].
