Which data structure is used to implement a two-dimensional array in Python?Group of answer choicesList of listsList of tupleTuple of listTuple of tuple

Break Down the Problem

1. Identify the question: We need to determine which data structure in Python is used to implement a two-dimensional array.
2. Examine the provided options:
   • List of lists
   • List of tuple
   • Tuple of list
   • Tuple of tuple

Relevant Concepts

1. Two-Dimension Arrays: A two-dimensional array can be thought of as an array of arrays. In Python, the most common way to simulate a two-dimensional array is by using lists.

Analysis and Detail

1. List of Lists: This is an effective way to create a two-dimensional structure. Each element of the main list represents a row, and each of these elements can be a list representing the columns.
2. Other Options:
   • List of Tuples: This could work but is less common due to the immutability of tuples making it harder to modify.
   • Tuple of Lists: Similar to the previous option, but with lists as elements. It is also less common for mutable structures.
   • Tuple of Tuples: This structure is immutable and generally less flexible for the operations typically performed on arrays.

Verify and Summarize

• The most common and flexible way to create a two-dimensional structure in Python is using a list of lists.

Final Answer

The correct answer is List of lists.
