 # NumPy - Arrays - Resizing an Array

### Resize()

`resize()` function is used to create a new array of different sizes and dimensions.

`resize()` can create an array of larger size than the original array.

To convert the original array into a bigger array, `resize()` will add more elements (than available in the original array) by copying the existing elements (repeated as many times as required) to fill the desired larger size.

Below is the syntax of `resize()` function:

``````ndarray.resize(new_shape, refcheck=True)
``````

With the above `resize()` function, enlarging an array to a larger size will retain the existing values of the original array, but missing entries/values will be filled with zeros.

Example code

``````import numpy as np

my_arr = np.array([ [0,1], [2,3] ])

my_arr.resize( (2, 3) )  # need two rows and one column

print(my_arr)
``````

output will be:

``````array[ [0, 1, 2],
[3, 0, 0] ]
``````
INSTRUCTIONS

(1) Please `import numpy as np`

(2) Please create a (2X4) numpy array (i.e. with 2 rows and 4 columns) called `my_arr` with values - 1,2,3,4,5,6,7 and 8, using `array()` function of numpy library

``````<<your code comes here>> = np.array(<<your code comes here>>)
``````

(3) Please apply `resize()` function on this `my_arr` array to convert this (2X4) array into a (3x4) array.

``````my_arr.resize(<<your code comes here>>)
``````

(4) Please print this array (`my_arr`) to see its values
