这个 努比。零() 函数返回给定形状和类型的新数组,其中包含零。 语法:
null
numpy.zeros(shape, dtype = None, order = 'C')
参数:
shape : integer or sequence of integers order : C_contiguous or F_contiguous C-contiguous order in memory(last index varies the fastest) C order means that operating row-rise on the array will be slightly quicker FORTRAN-contiguous order in memory (first index varies the fastest). F order means that column-wise operations will be faster. dtype : [optional, float(byDeafult)] Data type of returned array.
返回:
ndarray of zeros having given shape, order and datatype.
代码1:
# Python Program illustrating # numpy.zeros method import numpy as geek b = geek.zeros( 2 , dtype = int ) print ( "Matrix b : " , b) a = geek.zeros([ 2 , 2 ], dtype = int ) print ( "Matrix a : " , a) c = geek.zeros([ 3 , 3 ]) print ( "Matrix c : " , c) |
输出:
Matrix b : [0 0] Matrix a : [[0 0] [0 0]] Matrix c : [[ 0. 0. 0.] [ 0. 0. 0.] [ 0. 0. 0.]]
代码2:操作数据类型
# Python Program illustrating # numpy.zeros method import numpy as geek # manipulation with data-types b = geek.zeros(( 2 ,), dtype = [( 'x' , 'float' ), ( 'y' , 'int' )]) print (b) |
输出:
[(0.0, 0) (0.0, 0)]
