问题描述
我要序列化一个用复数填充的ndarray/列表,示例代码在这里:
I want to serialize an ndarray/list filled with complex number, the example code is here:
a = [None]
a[0] = 0.006863076166054825+0j
a
[(0.006863076166054825+0j)]
>>> b = json.dumps(a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\Python27\lib\json\__init__.py", line 243, in dumps
return _default_encoder.encode(obj)
File "D:\Python27\lib\json\encoder.py", line 207, in encode
chunks = self.iterencode(o, _one_shot=True)
File "D:\Python27\lib\json\encoder.py", line 270, in iterencode
return _iterencode(o, 0)
File "D:\Python27\lib\json\encoder.py", line 184, in default
raise TypeError(repr(o) + " is not JSON serializable")
TypeError: (0.006863076166054825+0j) is not JSON serializable
那该如何处理呢?
推荐答案
json.dumps(a)
将失败,因为该函数在尝试解释复数时无法处理该复数.传递值的唯一可能性是作为字符串:
The json.dumps(a)
will fail, because the function can not handle the complex number when it tries to interpret it. The only possibility to pass the value is as string:
a = [1]
a[0] = "0.006863076166054825+0j"
b = json.dumps(a)
print b
输出
["0.006863076166054825+0j"]
