如何替换每行中的最后一个特殊字符

def replace_last_special_character(text, new_character):
    # 定义特殊字符集合，可以根据实际需求进行修改
    special_characters = ['!', '@', '#', '$', '%', '^', '&', '*', '(', ')', '-', '_', '+', '=', '`', '~', '[', ']', '{', '}', ':', ';', '"', "'", '<', '>', ',', '.', '?', '/']

    # 查找最后一个特殊字符的位置
    last_special_character_index = -1
    for char in reversed(text):
        if char in special_characters:
            last_special_character_index = len(text) - text.index(char) - 1
            break
    
    # 如果找到了特殊字符，则进行替换
    if last_special_character_index != -1:
        text = text[:last_special_character_index] + new_character
    
    return text

# 测试样例
lines = [
    "Hello, world!",
    "This is a test line#",
    "Another line with special characters*",
    "No special characters in this line"
]

new_character = "@"

for line in lines:
    replaced_line = replace_last_special_character(line, new_character)
    print(replaced_line)
