全!python组合数据类型(容器类型) 组合数据类型为python解释器中内置的标准类型,包含组合数据类型在内的内置标准类型有:数字、序列、映射、类等等 序列类型 三种基本序列类型:列表(list)、元组(tuple)、range对象。除此之外python还有专为处理二进制数据(bytes)
假设有一个自定义对象列表，现在希望根据某些属性维护它们在列表中的顺序：from bisect import insort_leftclass CustomObject:def __init__(self, val):self.prop = val # The value to comparedef __lt__(self, other):return self.prop < other.propdef __repr__(self):return 'CustomObject({})'....

The fact that None is a singleton allows you to compare for None using the is keyword, like you did when creating decorators with optional arguments: Python if _func is None: return decorator_name else: return decorator_name(_func) Using is returns True only for objects that are the ...
