# 推导式-集合推导(pylang-f92bc49b)

## When to use

任务「集合推导」;对照:CPython 集合推导({x for ...} 去重 + 条件过滤,与列表/字典推导同族)。

## 克制条款(不适用条件)

条件不满足即不适用(负路由:输入不满足生效条件时返回 None/不执行)

## How to execute

set(items) 或 {x for x in items if cond(x)}

## Verification

- 单元样例 4 条(cases 断言)
- 物理基底:按 calibration 对照(编译/运行/断言裁决)

## References

- 单元库:python_code_units.py「推导式-集合推导」
