using index() on multidimensional lists

Question

For a one dimensional list, the index of an item is found as follows:

 a_list = [\'a\', \'b\', \'new\', \'mpilgrim\', \'new\']
 a_list.index(\'mpilgrim\')
         


        

Answer 1

list_2d = [[1,2],[3,4],[5,6]]

element = 1

index_row = [list_2d.index(row) for row in list_2d if element in row]

index_column = [row.index(element) for row in list_2d if element in row]
