使用python正则表达式匹配文件名末尾的"〜"

import re

filename = "example_file_name～"
pattern = r"～$"

match = re.search(pattern, filename)

if match:
    print("文件名末尾包含'～'")
else:
    print("文件名末尾不包含'～'")

import re

filenames = ["example_file_name1～", "example_file_name2", "example_file_name3～"]
pattern = r"～$"

matched_filenames = re.findall(pattern, "".join(filenames))

print("包含'～'的文件名：", matched_filenames)
