59. sorted() returns sorted list from a given iterable 不改变原来的, 有返回值 和.sort()的两个不同点:# sort is a method of the list class and can only be used with lists Second, .sort() returns None and modifies the values in place (sort()仅是list的方法,它会改变替换原来的变量) ...
同样builtin_methods是一个PyMethodDef数组,以空PyMethodDef结尾。熟悉的print、dir等函数都可在这找到定义。 这类Moudle还有很多,如io模块也是这样实现的。在Modules\_io\_iomodule.c可找到对应的定义。 3.内存中的builtin_function_or_method Python提供了一个叫id的函数,该函数可以查看对应对象在内存中的地址。

方法(Methods):实例的方法是定义在类中的函数,用于修改实例的状态或执行与实例相关的操作。方法的第一个参数通常是self,它代表实例本身。 Python的类支持所有面向对象编程(OOP)的标准特性: 类继承 :Python支持多继承,即一个类可以继承多个基类。这允许派生类继承多个基类的属性和方法。
dir()Returns a list of the specified object's properties and methods divmod()Returns the quotient and the remainder when argument1 is divided by argument2 enumerate()Takes a collection (e.g. a tuple) and returns it as an enumerate object ...

Python里面万物皆对象(object),整型也不例外,只要是对象,就有相应的属性 (attributes) 和方法(methods)。 【例子】 b = dir(int) print(b) # ['__abs__', '__add__', '__and__', '__bool__', '__ceil__', '__class__', # '__delattr__', '__dir__', '__divmod__', '__doc...
The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. # It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, # as well as most methods that the bytes type has, see Bytes and Bytearray Operations. # Without an ...
