python中这样的写法怎么理解

Answer 1

PEP0202 List Recursion: https://www.python.org/dev/pe...

Explain a little bit:

• result is a container containing tuples

• Each element in the container contains two values, the first represents the status True/False, and the second value is a dict

• If the status in the element is True, take the path value in the dict

Answer 2

Broken it apart to write:

for ok, x in results:
    if ok:
        print(x['path'])

In fact, it’s just an abbreviation. Its main function is to make the code simple and beautiful, so don’t worry too much.
