How to find size of an object in Python? Last Updated : 17 Jul, 2023 Comments Improve Suggest changes Like Article Like Report 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: Input: # Any Integer Valuesys.getsizeof(4) Expected Output: 4 bytes (Size of integer is 4bytes)Actual Output: 28 bytesHere's how we can interpret the actual output. Have a look at the table below: 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 sys # Getting size using getsizeof() method and lately # printing the same. a = sys.getsizeof(12) print(a) b = sys.getsizeof('geeks') print(b) c = sys.getsizeof(('g', 'e', 'e', 'k', 's')) print(c) d = sys.getsizeof(['g', 'e', 'e', 'k', 's']) print(d) e = sys.getsizeof({1, 2, 3, 4}) print(e) f = sys.getsizeof({1: 'a', 2: 'b', 3: 'c', 4: 'd'}) print(f) Output: Comment More infoAdvertise with us Next Article How to find size of an object in Python?
