如何按特定顺序将字符串拆分成行

def split_string_by_order(string, order):
    lines = []
    current_line = ""

    for char in string:
        if char in order:
            current_line += char
        else:
            if current_line:
                lines.append(current_line)
            current_line = ""

    if current_line:
        lines.append(current_line)

    return lines

# 示例用法
string = "abc123def456ghi789"
order = "123"
result = split_string_by_order(string, order)
print(result)
