Python C/C++ 拓展使用接口库(build in) ctypes 使用手册 ctypes 是一个Python 标准库中的一个库.为了实现调用 DLL,或者共享库等C数据类型而设计.它可以把这些C库包装后在纯Python环境下调用. 注意:代码中 c_int 类型其实只是 c_long 的别
Connector/Python supports a C extension that interfaces with the MySQL C client library. For queries that return large result sets, using the C Extension can improve performance compared to a“pure Python”implementation of the MySQL client/server protocol.Section 8.1, “Application Development with ...
Note The C Extension is not part of the pure Python installation. It is an optional module that must be installed using a binary distribution of Connector/Python that includes it, or compiled using a source distribution. See Chapter 4, Connector/Python Installation. ...
为Decimal对象设置自定义环境进行算术运算—参见decimal.localcontext文档。 为测试修补对象—参见unittest.mock.patch函数。 上下文管理器接口由__enter__和__exit__方法组成。在with的顶部,Python 调用上下文管理器对象的__enter__方法。当with块完成或由于任何原因终止时,Python 调用上下文管理器对象的__exit__方法。
