numpy.ma.MaskedArray.toflex()函數將掩碼數組轉換為flexible-type數組。返回的靈活類型數組將具有兩個字段:_data字段和_mask字段。 _data字段存儲數組的_data部分,而_mask字段存儲數組的_mask部分。
用法: numpy.ma.MaskedArray.toflex(self)
返回:[ndarray]具有兩個字段的新flexible-type ndarray:第一個元素包含值,第二個元素包含對應的掩碼布爾值。返回的記錄形狀與self.shape匹配。
代碼1:
# Python program explaining
# numpy.ma.MaskedArray.toflex() function
# importing numpy as geek
# and numpy.ma module as ma
import numpy as geek
import numpy.ma as ma
arr = geek.ma.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]],
mask =[0] + [1, 0]*4)
gfg = arr.toflex()
print (gfg)
輸出:
[[(1, False) (2, True) (3, False)] [(4, True) (5, False) (6, True)] [(7, False) (8, True) (9, False)]]
代碼2:
# Python program explaining
# numpy.ma.MaskedArray.toflex() function
# importing numpy as geek
# and numpy.ma module as ma
import numpy as geek
import numpy.ma as ma
arr = geek.ma.array([[11, 12, 13], [14, 15, 16], [17, 18, 19]],
mask =[0] + [1, 1]*4)
gfg = arr.toflex()
print (gfg)
輸出:
[[(11, False) (12, True) (13, True)] [(14, True) (15, True) (16, True)] [(17, True) (18, True) (19, True)]]
