dump json into yaml

pyyaml.dump() has "allow_unicode" option, it's default is None,all non-ASCII characters in the output are escaped. If allow_unicode=True write raw unicode strings.

yaml.dump(data, ff, allow_unicode=True)

bonus

json.dump(data, outfile, ensure_ascii=False)

This works for me:

#!/usr/bin/env pythonimport sysimport jsonimport yamlprint yaml.dump(yaml.load(json.dumps(json.loads(open(sys.argv[1]).read()))), default_flow_style=False)

So what we are doing is:

1. load json file through json.loads
2. json loads in unicode format - convert that to string by json.dump
3. load the yaml through yaml.load
4. dump the same in a file through yaml.dump - default_flow_style - True displays data inline, False doesn't do inline - so you have dumpable data ready.

Takes care of unicode as per How to get string objects instead of Unicode ones from JSON in Python?
