numpy.ndarray.copy() in Python

  • Last Updated : 28 Dec, 2018

numpy.ndarray.copy() returns a copy of the array.

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.

Code #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

 
Code #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]]
