num = 123 size = sys.getsizeof(num)print(f"The size of the integer object is: {size} bytes")上述代码会输出整数对象`123`在内存中的大小。这个大小包括了Python整数对象的头部信息以及实际存储整数值所需的空间。再举一个例子，如果我们有一个列表，并想查看这个列表对象本身（不包括列表中...
我们可以使用type()这个函数来确认a的数据类型,可以发现变量a的数据类型此时为int,也就是integer的缩写。 >>> type(a) <type 'int'> Python是一门动态类型语言,和C、JAVA等语言不同,你无需手动指明变量的数据类型,根据赋值的不同你可以随意更改一个变量的数据类型,举例来说刚才我们把“整数”这个数据类型赋值...
int : integer整数; str : string 字符串。 因此得到到的结果就是整数和字符串之间是没有办法进行运算的,原因在于他们的数据类型是不匹配的! 我将这两个值改为统一的字符集,就会有正常的执行结果! 在Python中数据类型主要包括:图中4种基础数据类型。

Return the “identity” of an object. This is an integer which is guaranteed to be unique and constant for this object during its lifetime. Two objects with non-overlapping lifetimes may have the sameid()value. CPython implementation detail:This is the address of the object in memory. ...

整数(Integer,简称int)是最常用的数值类型,和数学意义上的整数集相同包含正整数、负整数和零。受到硬件平台和操作系统的限制,Python基础数据类型中的整数的表示范围不能涵盖这个整数集合,只是整数集合的一个子集。 整数示例: 34135790-27-99675 上面示例的都是Python支持的整数类型。对于在代码中直接写出的数据,我们有...
These results are, of course, all hardware-dependent! YMMV. The variability in integer size in Python 3 is a hint that they may behave more like variable-length types (like lists). And indeed, this turns out to be true. Here's the definition of the C struct for intobjects in Python ...
