Problem

There is a problem with the JSON transformation in Python today:

Error display: expected string or buffer

The JSON content is as follows:

{u ' err_no ': 0, U ' corpus_no ': U ' 6594675362334657196 ', U ' err_msg ': U ' success. ', U ' result ': [u ' \uff0c '], u ' sn ': U ' 829195370711535442509 '}

"Analytical Solution"

After debugging, it turns out that single quotation marks are used to denote the string "'" By default in Python, so when a string character value is used, Python converts the double quotation marks to single quotes.

The JSON does not support single quotes. You can use the following method to convert

Json_string=json.dumps (s)

Str=json.loads (json_string)
