如果元素包含某些字符，则从列表中删除元素或设置元素

def remove_or_set_elements_with_characters(lst, characters, remove=True, set_value=None):
    for element in lst:
        if characters in element:
            if remove:
                lst.remove(element)
            else:
                lst[lst.index(element)] = set_value
    return lst

# 示例用法
my_list = ["apple", "banana", "orange", "grape"]
characters_to_check = "a"
new_list = remove_or_set_elements_with_characters(my_list, characters_to_check, remove=True)
print(new_list)
