eval The function cannot make json Character to dict Solutions for

json The string of cannot be used eval turn dict, Generally because json There are several special values in false,true,null
And in the python These are all capitalized ,null The corresponding is None

json_str = """{"appid": false, "appsecret": true, "city": null}"""
def handle_string_fit_eval(string) -> str:
""" Handle json Character satisfaction eval() :param string: :return: """
return str(string).replace('false', 'False').replace('true', 'True').replace(

sss = eval(handle_string_fit_eval(json_str))
print(sss)
