以上为运行的代码，运行的结果如下：
>>> text = u'你好，今天天气不错'
>>> text
'你好，今天天气不错'
>>> print(text)
你好，今天天气不错
>>> text = '\u4f60\u597d\uff0c\u4eca\u5929\u5929\u6c14\u4e0d\u9519'
>>> text
'你好，今天天气不错'
>>> print(text)
你好，今天天气不错
>>> text = u'\u4f60\u597d\uff0c\u4eca\u5929\u5929\u6c14\u4e0d\u9519'
>>> text
'你好，今天天气不错'
>>> print(text)
你好，今天天气不错
>>> text = '\\u4f60\\u597d\\uff0c\\u4eca\\u5929\\u5929\\u6c14\\u4e0d\\u9519'
>>> text
