How to Copy NumPy array into another array?

Many times there is a need to copy one array to another. Numpy provides the facility to copy array using different methods. In this

Copy NumPy Array into Another Array

There are various ways to copies created in NumPy arrays in Python, here we are discussing some generally used methods for copies created in NumPy arrays those are following.

• Using np.copy() Function
• Copy Given 2-D Array to Another Array
• Using Assignment Operator

Copy 1D Numpy Arrays into Another Using np.copy() Function

In the below example, the given Numpy array 'org_array' is copied to another array 'copy_array' using np.copy () function.

Output:

Original array: 
[ 1.54 2.99 3.42 4.87 6.94 8.21 7.65 10.5 77.5 ]
Copied array: 
[ 1.54 2.99 3.42 4.87 6.94 8.21 7.65 10.5 77.5 ]

Copy Given 2-D Array to Another Array Using np.copy() Function

In this example, the given 2-D Numpy array 'org_array' is copied to another array 'copy_array' using np.copy () function.

Output:

Original array: 
[[23 46 85]
 [43 56 99]
 [11 34 55]]
Copied array: 
[[23 46 85]
 [43 56 99]
 [11 34 55]]

NumPy Array Copy Using Assignment Operator

In the below example, the given Numpy array 'org_array' is copied to another array 'copy_array' using Assignment Operator.

Output:

Original Array: 
 [[99 22 33]
 [44 77 13]]
Copied Array: 
 [[99 22 33]
 [44 77 13]]
