list1[0] 和 list2[0] 标识相同,标识为: 1375086286224 (4)元组的标识是跟着变量名的,变量名不一样,标识也不一样,上例子: tuple1 = (10000,20000,30000) tuple2 = (10000,12000,15000) if tuple1[0] is tuple2[0]: print('tuple1[0] 和 tuple2[0] 标识相同,标识为:',
从上面代码可看出,只有数值型、字符串型和元组的情况下,a is b才为True,如果是list,dict或set型时,a is b为False。 不可变数据(3个):Number(数字)、String(字符串)、Tuple(元组)。 可变数据(3个):List(列表)、Dictionary(字典)、Set(集合)。 说说Python可变与不可变数据类型? 如果对于参考答案有不认同的...

总结:在Python中,只有小整数对象池中和字符串会调用已经存在的地址,其他的像list,tuple,dict都会重新创建一个新的对象。 总结 在Python中,is 和 == 还是有一些区别的,我们不能随意的去使用它。 但是现在我们编写代码基本都是在IDE上,例如pycharm,在pycharm中它对解释器进行了优化,不管你的值是否在区间[-5,256...
作用:像我们提供一个中间人即迭代器帮助我们迭代遍历使用for循环其实就实现了迭代器的功能,在遍历list,string,dict,tuple这些容器时,在for语句对容器对象调用的iter()方法返回一个定义next()方法的迭代器对象,它在函数中逐个访问容器内的元素,next和iter都是python内置函数。
3.Tuples: Tuples are similar to lists but are immutable. They are often used to store a collection of heterogeneous data. Loops can iterate over a tuple in the same way as a list. my_tuple = (1, "apple", 3.14) for item in my_tuple: ...
