1. import sys

Answer)
sys is meant for specific parameters and functions which is a module which provides access to the variables used or maintained by the interpreter and to the functions which are responsible for strongly interacting with the interpreter. These are in the sys.argv. The import sys statement import all these to be used in the script.

2. sys.getsizeof(object)

sys.getsizeof(object) returns the size of the object in bytes. The object which can be passed in the method can be of any type of object and sys.getsizeof(object) returns the memory size of the object.
