I don't understand now, just say a little according to my idea.
A python chased you and became a man. Maybe there is only one person around you, and you feel threatened, and this python is the "symbol" of this person in your dream (Freud's theory). However, you can ask yourself if you have any special feelings about python. Or, you think python will think of something else. This will help you to interpret your dreams.
The person who helps you catch the python is the "noble". Maybe your subconscious is reminding you that you have met someone who can help you. In addition, you need to see whether the focus of your dream is "chasing your python" or "someone helping you", which may be a little biased. Of course, two people may be together.
Isn't it very detailed about your previous dream? Personally, I think it may be a sexual dream. But this is a normal phenomenon, so there is no need to be afraid or alarmed.
