np.concatenate
In this video, I demonstrate how to use the concatenate function in the NumPy library. Documentation and other information about NumPy are available at their official website: https://numpy.org/. To explain how np.concatenate is used, it basically puts two or more arrays (in the NumPy sense) together. The dimension of the concatenation is decided by the named parameter, "axis." Which can be set to 0 or 1 for 2D arrays. The "axis" parameter is also used in a lot of other functions, so I attempt to explain what it means and how to use it.
