Summary This blog post provides an overview of Python lists and Numpy arrays, clarifying some of the terminologies, and some helpful analogies when dealing with higher dimensional data. It explains how to nest lists to create 1, 2, 3 and 4-dimensional lists, and how to convert them to numpy arrays. It also provides examples of how to perform vector operations and how to use the data attribute "ndim" to verify the dimension of the numpy array.

How to Convert a List to a NumPy Array? – Finxter

Summary The np.array() function can be used to convert a list of lists into a NumPy array, even if the inner lists have a different number of elements. There are three different strategies to convert a list of lists into a NumPy array, such as using the standard np.array() function, making an array of arrays, or making the lists equal in length. To become more successful in coding, it is important to focus on practical coding projects that earn you money and solve real problems for people.
