numpy . ma . maskearray . toflex()函数–Python
原文:https://www . geeksforgeeks . org/numpy-ma-masked array-toflex-function-python/
numpy.ma.MaskedArray.toflex() 函数将一个屏蔽数组转换成一个灵活类型的数组。返回的灵活类型数组将有两个字段:数据字段和掩码字段。数据字段存储数组的数据部分，掩码字段存储数组的掩码部分。
语法:numpy . ma . maskearray . toflex(self)
Return:【ndarray】一个新的灵活类型的 ndarray，有两个字段:第一个元素包含一个值，第二个元素包含对应的 mask boolean。返回的记录形状与 self.shape 匹配。
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)]]
代码#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)
输出:
[[(11, False) (12, True) (13, True)]
[(14, True) (15, True) (16, True)]
[(17, True) (18, True) (19, True)]]
