# 静态出现次数统计

源码版本：`2f2318653f6f794dddd321eff7c9d4b7b174643f`。

扫描全部 **381** 个 Git 跟踪 Python 文件，**90** 个文件含目标记录；解析错误 **0** 个。

计数单位是源码中的静态出现位置，不是执行次数。导入、直接调用、非调用引用、语法、实例候选五组分别计数。调用的函数表达式不再重复记为非调用引用。

## 按记录种类

| 种类 | 次数 |
| --- | ---: |
| import | 147 |
| async_def | 281 |
| async_generator_def | 7 |
| async_protocol_def | 0 |
| await | 409 |
| async_with | 42 |
| async_for | 1 |
| async_comprehension | 0 |
| async_yield | 7 |
| api_call | 433 |
| api_reference | 85 |
| instance_candidate | 876 |
| **全部记录** | **2288** |

`async def` 总数为 **288** = 普通协程函数 **281** + 异步生成器函数 **7**。`async_yield` 另记生成器内部的 yield 位置。

直接目标标准库 API 合计 **518** = 调用 **433** + 非调用引用 **85**，包含下表明确标出的邻接机制。**876** 条实例候选不并入此数。
