numpy.ma.MaskedArray.toflex()函数– Python
numpy.ma.MaskedArray.toflex()
函数将掩码数组转换为灵活类型数组。返回的灵活类型数组将有两个字段:_data 字段和 _mask 字段。 _data 字段存储数组的 _data 部分,_mask 字段存储数组的 _mask 部分。
Syntax : numpy.ma.MaskedArray.toflex(self)
Return : [ndarray] A new flexible-type ndarray with two fields: the first element containing a value, the second element containing the corresponding mask boolean. The returned record shape matches self.shape.
代码#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)
输出 :
[[(1, False) (2, True) (3, False)]
[(4, True) (5, False) (6, True)]
[(7, False) (8, True) (9, False)]]
