15.'credits', 信用 class _Printer(builtins.object) | interactive prompt objects for printing the license text, a list of | contributors and the copyright notice. | | Methods defined here: | | __call__(self) | Call self as a function. | | __init__(self,…

64.'staticmethod', 返回静态方法 class staticmethod(object) | staticmethod(function) -> method | | Convert a function to be a static method. | | A static method does not receive an implicit first argument. | To declare a static method, use this idiom: | | c…

46.'memoryview',  返回给定参数的内存查看对象(Momory view).所谓内存查看对象,是指对支持缓冲区协议的数据进行包装,在不需要复制对象基础上允许Python代码访问. class memoryview(object) | Create a new memoryview object which references the given object. | | Methods defined here: | | __delitem__(self, key, /) | De…

32.'help', 接收对象作为参数,更详细地返回该对象的所有属性和方法 class _Helper(builtins.object) | Define the builtin 'help'. | | This is a wrapper around pydoc.help that provides a helpful message | when 'help' is typed at the Python interactive prompt. | | Calling help() at t…

11.'classmethod', 修饰符对应的函数不需要实例化,不需要 self 参数,但第一个参数需要是表示自身类的 cls 参数,可以来调用类的属性,类的方法,实例化对象等. class classmethod(object) | classmethod(function) -> method | | Convert a function to be a class method. # 将一个函数转换成类方法 | | A class method receives the class as…

6.'bool',  函数用于将给定参数转换为布尔类型,如果没有参数,返回 False. class bool(int) # 继承于int类型 | bool(x) -> bool # 创建bool类型的对象 | | Returns True when the argument x is true, False otherwise. # 参数x为真返回True,否则返回False. | The builtins True and False are the only two instances o…

71.'zip' , 函数用于将可迭代的对象作为参数,将对象中对应的元素打包成一个个元组,然后返回由这些元组组成的列表.如果各个迭代器的元素个数不一致,则返回列表长度与最短的对象相同,利用 * 号操作符,可以将元组解压为列表. class zip(object) | zip(iter1 [,iter2 [...]]) --> zip object | | Return a zip object whose .__next__() method returns a tuple where | th…

69.'type', 返回对象类型 class type(object) | type(object_or_name, bases, dict) | type(object) -> the object's type | type(name, bases, dict) -> a new type | | Methods defined here: | | __call__(self, /, *args, **kwargs) | Call self as a function. | | __de…

68.'tuple', 转换为元组类型 class tuple(object) | tuple() -> empty tuple | tuple(iterable) -> tuple initialized from iterable's items | | If the argument is a tuple, the return value is the same object. | | Methods defined here: | | __add__(self, value, /)…
