DESCRIPTION = """
|
|
输入参数：p0,p1,p2... 支持任意类型，可根据需要输入和选择输入参数
|
|
输出参数：p0,p1,p2... 支持任意类型，可根据需要输出
|
|
表达式：python的正确代码语法，多个参数输出需如下形式：tuple([p0,p1,p2,p3]) 对应出参：p0,p1,p2,p3
|
|
示例：
|
|
入参：p0,p1 表达式：p0>p1 出参：p0 比较大小返回bool类型用于判断选节点
|
|
入参：p0,p1 (p0类型IMAGE,p1类型INT) 表达式：p0[p1:p1+1] 出参：p0 返回指定下标的图片
|
|
入参：p0 (p0数组) 表达式：len(p0) 出参：p0 数组长度
|
|
入参：p0,p1 (p0类型LIST,p1类型INT) 表达式：p0[p1] 出参：p0 返回指定下标的元素
|
|
入参：p0 (p0类型字符串数组) 表达式：','.join(p0) 出参：p0 返回字符串数组‘,’分割合并的字符串
|
|
入参：p0 表达式：print('调试输出',p0) 出参：无 用于调试输出，查看数据结构
|
|
高级模式启用：可执行多行代码，返回值会必须赋值给“result” 否则会报错
