How can I check the memory usage of Python data structures?

How can I check the memory usage of Python data structures?

You can use the sys module's getsizeof() function to check the memory usage of individual objects.

Can you show me an example of using getsizeof()?

Sure! Here's a simple example:

import sys
my_list = [1, 2, 3]
print(sys.getsizeof(my_list))

What about more complex data structures like dictionaries?

For dictionaries, you can also use getsizeof(), but remember it only gives the size of the dictionary object itself, not the objects it contains.

Is there a way to get the total memory usage of all items in a dictionary?

Yes! You can iterate through the dictionary and sum the sizes of each key and value using getsizeof().
