#006B Vectorization and Broadcasting in Python Master Data Science

A vectorization is basically the art of getting rid of explicit for loops whenever possible. With the help of vectorization, operations are applied to whole arrays instead of individual elements. The rule of thumb to remember is to avoid using explicit loops in your code. Deep learning algorithms tend to shine when trained on large datasets, so it's important that your code runs quickly. Otherwise, your code might take a long time to get your result.
