What is the method to convert a string into a list of individual words?

Hello there, I am working on a Python project and have a string containing a series of words. I need to convert this string into a list of individual words to perform further processing on each word. I have tried searching online for a solution but I am unsure how to go about it.

Can someone please provide me with guidance or code snippets to help me achieve this task? Any help or advice would be greatly appreciated.

Here is the sample string that I am working with:

str = "Hello world, how are you doing today?"

Thank you in advance for your assistance.
