用双反斜杠解码特殊字符字节

Question

x = 'Amazing!! Fantastic coffee and cakes to die for \\xf0\\x9f\\x98\\x80\\xf0\\x9f\\x98\\x80'

y = 'There is a line outside the door for good reason! Everything (and there is plenty) is absolutely excellent. As long as you\\xe2\\x80\\x99re a fan of the best freshly made French baked goods and enjoy an amazing croque monsieur, you\\xe2\\x80\\x99ll be happy here!'

如何解码这些字符串并存储在一个平面文件中，以在 csv 中显示所有表情符号和其他特殊字符而不是字节

Answer 1

您似乎有x 和y 作为str 类型。

你可以这样做来解码字符串：

x = 'Amazing!! Fantastic coffee and cakes to die for \xf0\x9f\x98\x80\xf0\x9f\x98\x80'
y = 'There is a line outside the door for good reason! Everything (and there is plenty) is absolutely excellent. As long as you\xe2\x80\x99re a fan of the best freshly made French baked goods and enjoy an amazing croque monsieur, you\xe2\x80\x99ll be happy here!'

print(bytearray([ord(c) for c in x]).decode('utf-8'))
print(bytearray([ord(c) for c in y]).decode('utf-8'))

打印：

Amazing!! Fantastic coffee and cakes to die for ??
There is a line outside the door for good reason! Everything (and there is plenty) is absolutely excellent. As long as you’re a fan of the best freshly made French baked goods and enjoy an amazing croque monsieur, you’ll be happy here!

编辑：如果您的字符串带有双反斜杠，您可以使用ast.literal_eval 对其进行解码：

x = 'Amazing!! Fantastic coffee and cakes to die for \\xf0\\x9f\\x98\\x80\\xf0\\x9f\\x98\\x80'
y = 'There is a line outside the door for good reason! Everything (and there is plenty) is absolutely excellent. As long as you\\xe2\\x80\\x99re a fan of the best freshly made French baked goods and enjoy an amazing croque monsieur, you\\xe2\\x80\\x99ll be happy here!'

from ast import literal_eval

print(literal_eval('b"""' + x + '"""').decode('utf-8'))
print(literal_eval('b"""' + y + '"""').decode('utf-8'))
