 # Numpy - Arrays - Special Types of Arrays - Array with Random Values

Below are few more special NumPy arrays which you can create to contain random values.

For example:

1. NumPy array with all its elements values as random values (using `random.rand()` function of NumPy)
2. NumPy array with all its elements values as uninitialized values (initialized with some random values which you are not aware of - using `empty()` function of NumPy)
INSTRUCTIONS

Note: Please import numpy as np

(1) NumPy array with all its elements values as random values (using `random.rand()` function of NumPy)

• Create your NumPy array by passing the above the desired dimensions of the array (say (3,4)) to `random.rand()` function below

``````my_rand_array = np.random.<<your code comes here>>(3,4)
``````

The above NumPy array `my_rand_array` will have random float values between 0.0 and 1.0

(2) NumPy array with all its elements values as uninitialized values (initialized with some random values which you are not aware of - using the `empty()` function of NumPy)

• Create a tuple indicating dimensions of the desired array

``````tup_dim = (3, 4)
``````
• Now, create your NumPy array by passing the above tuple (`tup_dim`) to `empty()` function below

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

The above NumPy array `my_uninitialized_array` will be filled with random (also unknown) float values between 0.0 and 1.0
