Complete Python NumPy Tutorial (Creating Arrays, Indexing, Math, Statistics, Reshaping)

Check out https://stratascratch.com/?via=keith to practice your Python Pandas data science skills! This video overviews the NumPy library. It provides background information on how NumPy works and how it compares to Python's Built-in lists. This video goes through how to write code with NumPy. It starts with the basics of creating arrays and then gets into more advanced stuff. A full video timeline can be found in the comments.
