在转换字母(Devnagari to English)时，请列表索引

Question

我当前正在尝试用英语字母映射devnagari脚本。但是偶尔，我会遇到错误列表索引范围内。我不想错过任何列表。这就是为什么我不想使用错误处理，除非有必要。您能否查看我的脚本并帮助为什么发生此错误？在我的Word文件中，我找到了哪个单词会导致错误，但是如果我从该单词上下使用几个句子，那么错误就不存在。即我认为错误在字符串的特定长度上发生。

   clean=[]
dafuq=[]
clean_list = []
replacements = {'अ':'A','आ':'AA', 'इ':'I', 'ई':'II', 'उ':'U','ऊ':'UU', 'ए':'E', 'ऐ':'AI',

                 for char in ['।', ',', '’', '‘', '?','#','1','2','3','4','0','5','6','7','8','9',

                     if char in word:
                        word = word.replace(char, '')
                 if word.strip():
                  clean_list.append(word)
              f_chunk = f.read(chunk_size)
              for clean_word in clean_list:

               final_word=  (''.join(test_word))
               dafuq.append(final_word)
               print (final_word)
  f_chunk = f.read(chunk_size)

这是我在

问题带有一些Unicode字符。它在删除它们后起作用。
