How to Create Arrays and Functions in Python - Complete Python NumPy Tutorial for Beginners #2

This is the complete Python NumPy tutorial for beginners video #2 and in this video, we walk through how to create Arrays and Functions in Python using NumPy. This is especially important for any data analytics or data science work. We dive right into create NumPy arrays using various functions like zeros(). ones(), full(), arange(), linspace(), random.random(), random.normal(), random.randint(), eye(), and empty(). I end with a short lecture on NumPy data types that could be used to create the arrays.

Python numpy documentation for the functions covered:
np.zeros(): https://numpy.org/doc/stable/reference/generated/numpy.zeros.html
np.ones(): https://numpy.org/doc/stable/reference/generated/numpy.ones.html
np.full(): https://numpy.org/doc/stable/reference/generated/numpy.full.html
np.arange(): https://numpy.org/doc/stable/reference/generated/numpy.arange.html
