也許這個問題很愚蠢。python json.loads on str
s="{'x':1}"
t='{"x":1}'
json.loads（S）帶來的異常：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/Cellar/python/2.7.3/lib/python2.7/json/__init__.py", line 326, in loads
return _default_decoder.decode(s)
File "/usr/local/Cellar/python/2.7.3/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/local/Cellar/python/2.7.3/lib/python2.7/json/decoder.py", line 382, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 1 (char 1)
而json.loads（t）是正確的：
{u'x': 1}
有什麼不同？先謝謝你。
