[英]Python find all fuzzy matching sequences in a string
I have a large string and I want to find all the input sequences that are matching in this string. 我有一个大字符串,我想找到与此字符串匹配的所有输入序列。
So for example, I want to find all the possible matches of defensive rebound in: 因此,例如,我想在以下位置找到防守篮板的所有可能匹配项:
Player xy had 10 defensive rebounds only in the 3rd quarter of a match that was a defensive battle between 2 teams that have a defensive rebound rate of over 80% and moreover the average number of rebounds in the defence by player was a staggering 3.5
球员xy仅在比赛的第3季度才获得10个防守篮板 ,这是两支球队之间的防守战, 防守篮板率均超过80%,而且该球员在防守中的平均篮板数达到惊人的3.5
I want to find all the bold words and after that extract them. 我想找到所有粗体字,然后将其提取出来。
I managed to build a script that does the extraction but it only works for exact matches. 我设法建立了执行提取的脚本,但它仅适用于完全匹配。
I was thinking of using difflib.SequenceMatcher
but I got stuck. 我当时在考虑使用
difflib.SequenceMatcher
但是我陷入了困境。
You can use regex in python, and you should have a goog pattern to extract them. 您可以在python中使用regex,并且应该使用goog模式提取它们。
For example: 例如:
import re
#Find [defence(s)][space][rebound(s)][space][any word]
re.findall('defensive[\w]* rebound[\w]* [\w]+', s)
#Find [rebound(s)][space][any word][space][any word][space][any word]
re.findall('rebound[\w]* [\w]+ [\w]+ [\w]+', s)
findall
return a list of matches findall
返回匹配列表
If all your matches are in the same form of bold words you can extract them with: 如果您所有的匹配项都使用粗体字形式,则可以使用以下方式将其提取:
re.findall('rebound[ \w]*defence', s)
re.findall('defensive[\w]* rebound[\w]*[ rate]*', s)
