Question
Which of the following lines of code would change matrix2 but not matrix3?
[]
matrix1 =
matrix1[0]
matrix1[1][1] = 0
None of the above
=
[[6, 7]]
Transcribed Image Text:Which of the following lines of code would change matrix2 but not matrix3? [] matrix1 = matrix1[0] matrix1[1][1] = 0 None of the above = [[6, 7]]
Suppose that matrix1 is the nested list
[[[0, 0], [0, 0]], [[1, 1], [1, 1]], [[2, 2], [2, 2]]]
Let matrix2 be a shallow copy of matrix1, and let matrix3 be a deep copy of matrix1.
