In python, the usage of sys.getsizeof() can be done to find the storage size of a particular object that occupies some space in the memory. This function returns the size of the object in bytes. It takes at most two arguments i.e Object itself.
Note: Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to.
Examples:Â Â
Input:
# Any Integer Value
sys.getsizeof(4)
Expected Output: 4 bytes (Size of integer is 4bytes)
Actual Output: 28 bytes
Here’s how we can interpret the actual output. Have a look at the table below:Â
|
Type of Object |
Actual Size |
Notes |
|---|---|---|
|
int |
28 |
NA |
|
str |
49 |
+1 per additional character (49+total length of characters) |
|
tuple |
40 (Empty Tuple) |
+8 per additional item in a tuple ( 40 + 8*total length of items ) |
|
list |
56 (Empty List) |
+8 per additional item in a list ( 56 + 8*total length of items ) |
|
set |
216 |
0-4 take the size of 216. 5-19 take size 728. 20th will take 2264 and so on… |
|
dict |
232 |
0-5 takes a size of 232. 6-10 size will be 360. 11th will take 640 and so on… |
|
func def |
136 |
No attributes and default arguments |
Example:
Python3
import sysÂ
# Getting size using getsizeof() method and lately# printing the same.a = sys.getsizeof(12)print(a)Â
b = sys.getsizeof('Lazyroar')print(b)Â
c = sys.getsizeof(('g', 'e', 'e', 'k', 's'))print(c)Â
d = sys.getsizeof(['g', 'e', 'e', 'k', 's'])print(d)Â
e = sys.getsizeof({1, 2, 3, 4})print(e)Â
f = sys.getsizeof({1: 'a', 2: 'b', 3: 'c', 4: 'd'})print(f) |
Output:
