Creating NumPy arrays

There is more than one way to create NumPy arrays. The following are some of the ways you can create them:

  • By transforming an existing data structure into an array
  • By creating an array from scratch and populating it with default or calculated values
  • By uploading some data from a disk into an array

If you are going to transform an existing data structure, the odds are in favor of you working with a structured list or a pandas DataFrame.
