Subsetting 2D arrays
Subsetting 2D arrays is similar to subsetting nested lists. In a 2D array, the indexing or slicing must be specific to the dimension of the array:
array[row_index, column_index]
numpy
is imported as np
and the 2D array stock_array_transposed
(from the previous exercise) is available in your workspace.
