如何把python里面的list變成json對象？

代碼示例：

# list 轉成Json格式數據

def listTojson(lst):

import json

import numpy as np

keys = [str(x) for x in np.arange(len(lst))]

list_json = dict(zip(keys, lst))

str_json = json.dumps(list_json, indent=2, ensure_ascii=False) # json轉為string

return str_json

結果

{

"0": "123",

"2": "34",

"3": "456",

"1": "345"

}
