英文:
size of variable in python
问题
我想知道一个变量占用了多少内存。
让我们假设这个例子：
import numpy as np
t = [np.random.rand(10000) for _ in range(1000)]
变量 t 占用多少兆字节的内存？
我运行了：
sys.getsizeof(array_list)
我得到了 8856，这似乎对于 t 中包含的信息量来说很低。
最好的问候。
英文:
I would like to know how much memory is being occupied by a variable.
Let us assume this example:
import numpy as np
t = [np.random.rand(10000) for _ in range(1000)]
How much memory in megabytes is t occupying?
I ran:
sys.getsizeof(array_list)
and I am getting 8856 which seems low for the amount of information contained in t
Best Regards.

我猜这个（不依赖外部库）可以完成任务：
def deepgso(ob):
size = sys.getsizeof(ob)
if isinstance(ob, (list,tuple,set)):
for element in ob:
size+=deepgso(element)
if isinstance(ob, dict):
for k,v in ob.items():
size+=deepgso(k)
size+=deepgso(v)
return size
英文:
I guess this (without resorting to external libraries) does the trick:
def deepgso(ob):
size = sys.getsizeof(ob)
if isinstance(ob, (list,tuple,set)):
for element in ob:
size+=deepgso(element)
if isinstance(ob, dict):
for k,v in ob.items():
size+=deepgso(k)
size+=deepgso(v)
return size

Short answer: sys.getsizeof(variable)
Example:
import sys
integer = 10
print("The size of the integer variable is:", sys.getsizeof(integer), "bytes.")
