如何将Dynamo项目从Scan转换为dict / json？

Question

I am using boto to retrieve dynamo Items from a scan.

for item in scan_results:
    print item

I can access each property with:

for item in scan_results:
    print item['propA']

for item in scan_results:
    print json.dumps(item) # This does not work

How do I convert each item to a json object or a dict? I want to avoid having to iterate over the keys in item and generating a dict through loops if i can avoid it.

Answer 1

这个怎么样？

for item in scan_results: print json.dumps(dict(item))
