代码#1：

# Python program explaining
# numpy.MaskedArray.compressed() function
  
# importing numpy as geek  
# and numpy.ma module as ma 
import numpy as geek 
import numpy.ma as ma
  
arr = geek.ma.array(geek.arange(10), mask =[0]*6 + [1]*4)
gfg = arr.compressed()
  
print(gfg)

输出 ：

[0 1 2 3 4 5]
