记录一下,查看python运行当前范围内的变量、方法和定义的类型 会占用多少memory 借助内置模块 sys的 getsizeof即可。 看到该函数的介绍,返回字对象的字节大小。 科班出身的码畜一直被灌输一条上帝圣经:“一个int占4个字节,一个char占1个字节,一个float占4个字节。。。”, ...
1. The sys.getsizeof() Function. To retrieve the size of a Python object, the `sys` module’s `getsizeof()` function proves to be a valuable asset. It should be noted that the size returned may not always reflect the complete memory footprint due to the complex nature of Python’s...
