使用正则表达式过滤列表 [英] Filter list with regex

问题描述

我认为这是一项简单的任务，但我是正则表达式的新手，所以无法弄清楚.我想过滤一个包含以下内容的列表:ANY"-ANY"-ANY"

I think this is a easy task but I'm new to regex so can't figure it out. I want to filter a list that contains something like this: "ANY"-"ANY"-"ANY"

输入:

List1 = ["AB.22-01-01", "AB.33-01-44", "--4", "AA.44--05", "--"]

输出:

List2 = ["AB.22-01-01", "AB.33-01-44"]

每个项目将包含两个-"，但我只想获取-"两侧带有文本的项目.

Each item will contain two "-" but I only want to get the ones with text on each sides of the "-".

推荐答案

尝试使用 re模块:

import re

p = re.compile('^.+-.+-.+$')
l1 = ["AB.22-01-01", "AB.33-01-44", "--4", "AA.44--05", "--"]
l2 = [ s for s in l1 if p.match(s) ]
