Editor to share with you how python checks the memory usage of objects. I hope you will get something after reading this article. Let's discuss it together.

Check the memory usage of an object

Use sys.getsizeof () to check the memory usage of an object:

Import sys mylist = range (0, 10000) print (sys.getsizeof (mylist)) # 48

Why is this huge list only 48 bytes? This is because the class returned by the range function appears as a list. Compared with using the actual number list, the storage efficiency of the number sequence is much higher. We can use list derivation to create a list of actual numbers in the same range:

Import sys myreallist = [x for x inrange (0, 10000)] print (sys.getsizeof (myreallist)) # 87632

By using sys.getsizeof (), we can learn more about Python and memory usage.
