從Python3的unicode文本文件中刪除一個unicode範圍

Question

我有一個由範圍q到r和s到t組成的Unicode文本文件。我想刪除範圍s到t（這是中文），留下q到r（這是英文）。

我如何在Python3中做到這一點？

Answer 1

使用字符串翻譯方法。引用3.1.3 Std Lib文檔：

str.translate(map) 
Return a copy of the s where all characters have been mapped through the map 
which must be a dictionary of Unicode ordinals (integers) to Unicode ordinals, 
strings or None. Unmapped characters are left untouched. Characters mapped to 
None are deleted. 

You can use str.maketrans() to create a translation map from 
character-to-character mappings in different formats.
