Recommended Reading:Python Dictionary del With Tuples and Strings Note:You can't delete items of tuples and strings in Python. It's because tuples and strings are immutables; objects that can't be changed after their creation. my_tuple = (1,2,3)# Error: 'tuple' object doesn't support...
Whenever you create an object in Python, the underlying C object (CPython) has both a Python type (such as list, dict, or function) and a reference count. 在Python中每一个对象的核心就是一个结构体PyObject,它的内部有一个引用计数器(ob_refcnt)。程序在运行的过程中会实时的更新ob_refcnt的值...

del魔法 python python魔法方法汇总 Python中的魔术方法 所谓魔法函数(Magic Methods),是Python的一种高级语法,允许你在类中自定义函数,并绑定到类的特殊方法中。比如在类A中自定义__str__()函数,则在调用str(A())时,会自动调用__str__()函数,并返回相应的结果。
我们的 Python 代码继续往下运行,这里执行到一条 def func(),从字节码指令中也可以看出端倪 MAKE_FUNCTION。没错这条指令是用来创建函数的。Python 是动态语言,def 实际上是执行一条指令,用来创建函数(class 则是创建类的指令),而不仅仅是个语法关键字。函数并不是事先创建好的,而是执行到的时候才创建的。
