如何从具有负值的拆分字符串中获取数组

def get_array_from_split_string(split_string, separator):
    result = []
    split_list = split_string.split(separator)
    for s in split_list:
        if "-" in s:
            negative_value = int(s)
            result.append(negative_value)
    return result

# 示例用法
split_string = "1,2,-3,4,-5,6"
separator = ","
array = get_array_from_split_string(split_string, separator)
print(array)
