It should be useful (assuming the course is good) if you want to get a job programming in Python, although other skills are needed too, but you can build those as you go along.

It can be useful in many ways even if you don't want to get a job programming.

For example, writing simple programs related to any aspect of your personal, professional, business, or social life. You could write small software tools to automate or facilitate tasks in these areas, as many people do.

That could be both useful and fun.
