numpy - ndarray - how to remove rows based on another array

Question

I want to remove rows from a ndarray based on another array. for example:

k = [1,3,99]

n = [
  [1,\'a\']
  [2,\'b\']
  [3,\'c\']
  [4,\'c\']
  [.....]
  [99, \'         


        

Answer 1

If your data structure is list, please find simple solution as below, however you can convert into list by list() method.

def check(list):
 k=[1,3,99]
 if(list[0] not in k): 
  return list

final_list = map(check,n)
final_list = final_list.remove(None)
print final_list
