字符串字符串

Question

我正在尋找一種優雅的方式來將字典對象的值編碼爲字符串類型。像下面這樣：

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

到

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

謝謝你很多！

Answer 1

簡單的另一個字典理解：

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，做舊的方式：

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

（順便說一句無懼轉換的開銷已存在str至str：Should I avoid converting to a string if a value is already a string?）
