那为什么要打印（str1）== currency.txt内容？
答案 0 :(得分：-1)
您的文件似乎包含 literal Unicode转义符，这表明用于生成文件的方法是错误的。
您可以通过对文件进行编码然后使用 unicode-escape 编解码器进行解码来解决此问题。
>>> # repr of the data
>>> content
'Alba 3526 (\\u062f.\\u062c) | Peso ($) | ARS | 28 (\\u058f) ani Manat (\\u20bc)\n'
>>> # str of the data
>>> print(content)
Alba 3526 (\u062f.\u062c) | Peso ($) | ARS | 28 (\u058f) ani Manat (\u20bc)
>>> print(content.encode('latin-1').decode('unicode-escape'))
Alba 3526 (د.ج) | Peso ($) | ARS | 28 (֏) ani Manat (₼)
latin-1编码将文本转换为字节，unicode-escape解码取消转义unicode文字，以便Python正确解释它们。
