Numpy MaskedArray.flatten() function | Python

Last Updated : 3 Oct, 2019
numpy.MaskedArray.flatten() function is used to return a copy of the input masked array collapsed into one dimension.
Syntax : numpy.ma.flatten(order='C') Parameters: order : [‘C’, ‘F’, ‘A’, ‘K’, optional] Whether to flatten in C (row-major), Fortran (column-major) order, or preserve the C/Fortran ordering from a. The default is ‘C’. Return : [ ndarray] A copy of the input array, flattened to one dimension.
Code #1 :
Output: 
Input array : [[ 10 20]
 [-10 40]]
Masked array : [[-- 20]
 [-10 40]]
Output flattened masked array : [-- 20 -10 40]
  Code #2 :
Output: 
Input array : [[[ 2.e+08 3.e-05]]

 [[-4.e-06 2.e+05]]]
Masked array : [[[-- 3e-05]]

 [[-4e-06 200000.0]]]
Output flattened masked array : [-- -4e-06 3e-05 200000.0]
