As the outer container is a list you have to provide an index:
results[1]["score"]
You can also search for a matching item:
for result in results:
if result["name"] == "gengyang":
print(result["score"])
but when the list grows performance will suffer.
General note: you will have a better experience learning Python when you
read some introductory text first, to get the big picture.
