Display Memory Usage of Multiple Data Items in Python

Program Overview

This Python program calculates and displays the memory usage of multiple data items.
It uses the sys.getsizeof() function to measure memory in bytes.

Python Code:


import sys

# Define sample data items
items = [
    42,                      # Integer
    3.14,                    # Float
    "Hello Shahin عزیز دلم", # String
    [1, 2, 3],               # List
    {"a": 1, "b": 2},        # Dictionary
]

# Display memory usage for each item
print("--- Memory Usage of Each Item ---")
for item in items:
    size = sys.getsizeof(item)
    print(f"{type(item).__name__}: {size} bytes")

Sample Output:


--- Memory Usage of Each Item ---
int: 28 bytes  
float: 24 bytes  
str: 78 bytes  
list: 80 bytes  
dict: 232 bytes

Step-by-Step Explanation:

- A list of sample items is defined, including integers, floats, strings, lists, and dictionaries
- The sys.getsizeof() function is used to measure memory usage
- The type and memory size of each item are printed in a structured format
