SystemExit Raised by the sys.exit() function. TypeError Raised when a function or operation is applied to an object of an incorrect type. UnboundLocalError Raised when a reference is made to a local variable in
2) 传递PyObject对象给函数,一般都是假设传递过来的对象的引用计数已经是protected,因此在函数内部不需要调用Py_INCREF。不过,如果想要参数存活到函数退出,可以调用Py_INCREF。 When you pass an object reference into another function, in general, the function borrows the reference from you -- if it needs to...
The Python interpreter uses whitespace indentation to determine which pieces of code are grouped together in a special way — for example, as part of a function, loop, or class. How much space is used is not typically important, as long as it is consistent. If two spaces are used to ...

2.2.4 引用变化(Reference Counting Changes) 增加引用:当其他变量也指向同一个对象时,该对象的引用计数会增加。 another_ref=my_list 减少引用:当引用该对象的变量被重新赋值或作用域结束时,引用计数会减少。如果引用计数变为0,则表示没有引用指向此对象,进入垃圾回收流程。
builtin_methods 中每一个函数对应一个 PyMethodDef 结构,会基于它创建一个 PyCFunctionObject 对象,这个对象是Python 对函数指针的包装。 代码语言:cpp 代码运行次数:0 运行 AI代码解释 structPyMethodDef{constchar*ml_name;/* The name of the built-in function/method */PyCFunction ml_meth;/* The C fun...
The name of the Python handler function. In the example above, if the file is namedlambda_function.py, the handler would be specified aslambda_function.lambda_handler. This is the default handler name given to functions you create using the Lambda console. ...
The only reference in b.py to a is the call to a.f(). But that call is in g() and nothing in a.py or b.py invokes g(). So life is good. But what happens if we attempt to import b.py (without having previously imported a.py, that is): >>> import b Traceback (most ...
If you're working with a multi-threaded app that uses native thread APIs (such as the Win32CreateThreadfunction rather than the Python threading APIs), it's presently necessary to include the following source code at the top of whichever file you want to debug: ...
