从Python列表项中删除标点符号

punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
list_with_punctuations = ["Hello", ",", "world", "!"]

# 使用循环遍历列表，判断每个元素是否为标点符号，如果是则删除该元素
list_without_punctuations = [x for x in list_with_punctuations if x.isalnum()]

print(list_without_punctuations)
# 输出: ['Hello', 'world']

import re

punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
list_with_punctuations = ["Hello", ",", "world", "!"]

# 使用正则表达式匹配和删除标点符号
list_without_punctuations = [re.sub(r'[^\w\s]', '', x) for x in list_with_punctuations]

print(list_without_punctuations)
# 输出: ['Hello', '', 'world', '']
