I've tried to save this dictionary in json or yaml file:

d = {'name': 'María Gómez', 'message': '¡Es una caña atómica!'}
with open(file, 'wt', encoding='iso8859-1') as file:
   json.dump(d, file)

However, the file content is not in that encoding and the non-ascii characters are escaped within json or yaml files. Therefore, I assume that the encoding file doesn't make sense. Or is there some languages or characters that the encoding could make sense with this type of files?

CodePudding user response：

import json
d = {'name': 'María Gómez', 'message': '¡Es una caña atómica!'}
json.dumps(d)
# '{"name": "Mar\\u00eda G\\u00f3mez", "message": "\\u00a1Es una ca\\u00f1a at\\u00f3mica!"}'
json.dumps(d, ensure_ascii=False)
# '{"name": "María Gómez", "message": "¡Es una caña atómica!"}'

Explanation (valid for json.dumps as well as for json.dump): JSON encoder and decoder basic usage:

If ensure_ascii is true (the default), the output is guaranteed to have all incoming non-ASCII characters escaped. If ensure_ascii is false, these characters will be output as-is.
