我想在文本文件中找到遵循特定单词顺序的行。例子：
customer is given as per below
customer are given not priority below
given given below customer
below customer information given
我试过这个，(?=.*customer)(?=.*given)(?=.*below)但力不从心。
它应该只给
customer is given as per below
customer are given not priority below
我希望顺序是相同的：“客户”排在第一位，“给定”排在第三位，“下面”应该排在第六位。
这有效：
import re
s = '''customer is given as per below
customer are given not priority below
given given below customer
below customer information given
customer is given not as per below'''
matches = re.findall('customer \S+ given \S+\s\S+ below', s)
for match in matches:
print(match)
