如何在文本中使用Python查找字符偏移量
我的目标是找出两个对齐的文本文件中匹配的字符串,然后找到每个文件中匹配字符串的起始字符位置。
doc1=['the boy is sleeping', 'in the class', 'not at home']
doc2=['the girl is reading', 'in the class', 'a serious student']
我尝试过的方法:
# find matching string(s) that exist in both document list:
matchstring=[x for x in doc1 if x in doc2]
Output=matchstring='in the class'
'
现在的问题是要找到在doc1和doc2中匹配字符串的字符位置(不包括标点符号,空格算在内)。
理想的结果:
Position of starting character for matching string in doc1=20
Position of starting character for matching string in doc2=20
关于文本对齐,有什么想法吗?谢谢。

嘿,兄弟,试试这个:
doc1=['the boy is sleeping', 'in the class', 'not at home']
doc2=['the girl is reading', 'in the class', 'a serious student']
temp=''.join(list(set(doc1) & set(doc2)))
resultDoc1 = ''.join(doc1).find(temp)
resultDoc2 = ''.join(doc2).find(temp)
print "Position of starting character for matching string in doc1=%d" % (resultDoc1 + 1)
print "Position of starting character for matching string in doc2=%d" % (resultDoc2 + 1)
这正好符合你的期望,效果很好!
