Convert a 2-dimensional array to a nested list Let’s start with example 1. EXAMPLE 1: Convert a 1-dimensional array to a list Here, we’re going to convert a simple 1-dimensional Numpy array to a Python list.
Numpy provides several built-in functions to create and work with arrays from scratch. An array can be created using the following functions: ndarray(shape, type):Creates an array of the given shape with random numbers array(array_object):Creates an array of the given shape from the list or...

In this example, we first import the NumPy library asnp. We then define a simple list calledmy_listcontaining integers. By passingmy_listto thenp.array()function, we create a NumPy array calledmy_array. Finally, we print the array to see the result. The output shows that the list has...
