字符串字符串

Question

我正在寻找一种优雅的方式来将字典对象的值编码为字符串类型。像下面这样：

{"a":"b","c":1,"e":None,"g":True} 

到

{"a":"b","c":"1","e":"None","g":"True"} 

谢谢你很多！

Answer 1

简单的另一个字典理解：

a = {"a":"b","c":1,"e":None,"g":True} 
a = {k:str(v) for k,v in a.items()} 

，或者如果你不想重建字典，做旧的方式：

for k in a.keys(): 
    a[k] = str(a[k]) 

（顺便说一句无惧转换的开销已存在str至str：Should I avoid converting to a string if a value is already a string?）
