The ndarray.copy() method returns a copy of the array.
It is used to create a new array that is a copy of an existing array but does not share memory with it. This means that making any changes to the original array won’t affect the existing array.
Example
Python3
# 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
Syntax
Syntax: numpy.ndarray.copy(order=’C’)
Parameters:
- Order : Controls the memory layout of the copy. ‘C’ means C-order, ‘F’ means F-order, ‘A’ means ‘F’ if a is Fortran contiguous, ‘C’ otherwise’K’ means match the layout of a as closely as possible
Returns: Copy of an Array
How to make a copy of a NumPy array
To make a copy of a NumPy array in Python, we use ndarray.copy method of the NumPy library
Let us understand it better with an example:
Example: Make a Copy of ndarray
Python3
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]]
