multidimensional-array

问题 Say i have a multidimensional array. For example: Array ( [0] => Array ( [animal_id] => 5494 [animal_name] => "Suzy" [animal_type] => "zebra" [animal_location] => 0 [animal_awake] => 1 [animal_age] => 3 ) [1] => Array ( [animal_id] => 5494 [animal_name] => "Joshua" [animal_type] => "panda" [animal_location] => 5 [animal_awake] => 0 [animal_age] => 8 ) [2] => Array ( [animal_id] => 5494 [animal_name] => "Debra" [animal_type] => "snake" [animal_location] => 7 [animal_awake] => 1 [animal_age] =>

问题 In Python numpy.unique can remove all duplicates from a 1D array, very efficiently. 1) How about to remove duplicate rows or columns in a 2D array ? 2) How about for nD arrays ? 回答1: If possible I would use pandas. In [1]: from pandas import * In [2]: import numpy as np In [3]: a = np.array([[1, 1], [2, 3], [1, 1], [5, 4], [2, 3]]) In [4]: DataFrame(a).drop_duplicates().values Out[4]: array([[1, 1], [2, 3], [5, 4]], dtype=int64) 回答2: The following is another approach which performs much

问题 I'm taking a class on C, and running into a segmentation fault. From what I understand, seg faults are supposed to occur when you're accessing memory that hasn't been allocated, or otherwise outside the bounds. 'Course all I'm trying to do is initialize an array (though rather large at that) Am I simply misunderstanding how to parse a 2d array? Misplacing a bound is exactly what would cause a seg fault-- am I wrong in using a nested for-loop for this? The professor provided the clock
