Python stands for strength and challenge, while robbery stands for difficulty and test. In your dream, Du Jie's failure may mean that you have met some difficulties or challenges in real life and feel that you can't overcome them.
This dream may also reflect your inner worries or fears. Du Jie's failure may mean that you lack confidence in overcoming some major problems or turning points in your life, or you may have experienced some failures in the past and still have a lingering fear about it.
In addition, pythons can also symbolize potential strength and passion. Du Jie's failure may mean that you didn't give full play to your potential.
However, it should be noted that the interpretation of dreams is not unique and definite, it depends on one's life experience and personal situation. So I can only provide a general explanation, and the specific meaning needs you to think and interpret according to your own situation.
