小编Ale*_*x T的帖子

我有一个代码,这样:

a = "\u0432"
b = u"\u0432"
c = b"\u0432"
d = c.decode('utf8')

print(type(a), a)
print(type(b), b)
print(type(c), c)
print(type(d), d)

并输出:

<class 'str'> ?
<class 'str'> ?
<class 'bytes'> b'\\u0432'
<class 'str'> \u0432

为什么在后一种情况下我看到的是字符代码,而不是字符？我如何将Byte字符串转换为Unicode字符串,在输出的情况下,我看到了字符而不是代码？

它在使用cyryllic时引用了UnicodeDecodeError.我在Python 3.3和Pycharm 2.7.2中遇到同样的问题.尝试在代码中硬编码编码,在Pycharm选项中手动指定编码,但没有效果.它仍然试图用cp1251 lib打开utf-8文件.
