python 中的 numpy . ndarray . copy()
哎哎哎:# t0]https://www . geeksforgeeks . org/num py-ndaarray-copy-in-python/
**numpy.ndarray.copy()**返回数组的副本。
语法: numpy.ndarray.copy(顺序='C ')
参数: 顺序:控制副本的内存布局。“C”表示 C 阶，“F”表示 F 阶，“A”表示“F”，如果 A 是 Fortran 连续的，则为“C”，否则为“C”。“k”表示尽可能匹配的布局。
代码#1:
# Python program explaining
# numpy.ndarray.copy() function
import numpy as geek
x = geek.array([[0, 1, 2, 3], [4, 5, 6, 7]],
order ='F')
print("x is: \n", x)
# copying x to y
y = x.copy()
print("y is :\n", y)
print("\nx is copied to y")
Output:
x is:
[[0 1 2 3]
[4 5 6 7]]
y is :
[[0 1 2 3]
[4 5 6 7]]
x is copied to y
代码#2:
# Python program explaining
# numpy.ndarray.copy() function
import numpy as geek
x = geek.array([[0, 1, ], [2, 3]])
print("x is:\n", x)
# copying x to y
y = x.copy()
# filling x with 1's
x.fill(1)
print("\n Now x is : \n", x)
print("\n y is: \n", y)
Output:
x is:
[[0 1]
[2 3]]
Now x is :
[[1 1]
[1 1]]
y is:
[[0 1]
[2 3]]
