a 为 string 类型
{"ret":0,"msg":"OK","data":[{"code":"000502","name":"绿景控股","total":1900,"cansel":1900,"newprice":17.25,"costprice":17.299},{"code":"002758","name":"华通医药","total":1100,"cansel":1100,"newprice":28.25,"costprice":28.354},{"code":"002778","name":"高科石化","total":800,"cansel":800,"newprice":39.01,"costprice":38.979}]}
请问如何高效将其转换为 dic 类型
直接采用 eval()函数失败，错误代码 SyntaxError: invalid character in identifier
谢谢

@bxb100 尝试 json.loads()会抛出异常： Unexpected UTF-8 BOM

r#6 @wdc63 BOM 问题，那就再试试 json.loads(a[1:]) 或者 json.loads(a[3:])

找到解决方案了
if a.startswith(u'\ufeff'):
a = a.encode('utf8')[3:].decode('utf8')
然后再 json.loads(a)
百度到的， text 包含 BOM 字符，在线接口编码的问题吧，谢谢各位。

这个问题可以先用 repr 把数据打出来看看，根据具体问题进行替换或者采用其他解决方式，然后再用 eval 解决。
