【问题描述】：

我有一个这样的字符串，我想把它转换成字典。

test=
'{"age":59.0,"bp":70.0,"sg":1.01,"al":3.0,"su":0.0,"rbc":1.0,"ba":0.0,"bgr":76.0,"bu":186.0,"sc":15.0,"sod":135.0,"pot":7.6,"hemo":7.1,"pcv":22.0,"wbcc":3800.0,"rbcc":2.1,"htn":1.0,"dm":0.0,"cad":0.0,"appet":0.0,"pe":1.0,"ane":1.0}'

我试过dict(test)，但它返回了一个错误：

ValueError: dictionary update sequence element #0 has length 1; 2 is required

如何将此字符串转换为字典？
