用python解码列表

Question

我有一个python列表

['Deals', "\\\\xe2\\\\x98\\\\x85What\\\\\\'s New\\\\xe2\\\\x98\\\\x85", '\\\\xc3\\\\x80la carte & Value Meals', 'Crispy Chicken', 'Share Box', 'Happy Meals', 'Desserts', 'McCafe\\\\xc3\\\\xa9', 'Beverages', 'Side Lines', 'Snack Time']

我想把它像"\\\\xe2\\\\x98\\\\x85What\\\\\\'s New\\\\xe2\\\\x98\\\\x85", '\\\\xc3\\\\x80la carte & Value Meals','McCafe\\\\xc3\\\\xa9'到'What's New, la carte & Value Meals,McCafe'一样解码 所需的输出没有任何结束编码（\\x98） 期望输出：

['Deals', "What's New", 'la carte & Value Meals', 'Crispy Chicken', 'Share Box', 'Happy Meals', 'Desserts', 'McCafe', 'Beverages', 'Side Lines', 'Snack Time']

Answer 1

您可以使用内置模块^a1}：

import re
l = ['Deals', "\\\\xe2\\\\x98\\\\x85What\\\\\\'s New\\\\xe2\\\\x98\\\\x85", '\\\\xc3\\\\x80la carte & Value Meals', 'Crispy Chicken', 'Share Box', 'Happy Meals', 'Desserts', 'McCafe\\\\xc3\\\\xa9', 'Beverages', 'Side Lines', 'Snack Time']
l = [re.sub(r'x\S\d',' ',s).replace('\\','').strip() for s in l]
print(l)

输出：

['Deals', "What's New", 'la carte & Value Meals', 'Crispy Chicken', 'Share Box', 'Happy Meals', 'Desserts', 'McCafe', 'Beverages', 'Side Lines', 'Snack Time']

---

re.sub(r'x\S\d',' ',s)将返回字符串s，其中每3个相邻字符在此模式中：

x，any character that's not a space，number

替换为一个空格
