How can I optimize my Python code for better memory efficiency?

You can optimize memory efficiency in Python by using generators instead of lists, minimizing global variables, and using built-in functions.

What are generators and how do they help with memory efficiency?

Generators are iterators that yield items one at a time and only when required, which saves memory compared to storing all items in a list.

Can you give me an example of using a generator?

Sure! Here's a simple generator function:

def count_up_to(n):
    count = 1
    while count <= n:
        yield count
        count += 1

This function yields numbers from 1 to n without storing them all in memory.

What other techniques can I use to reduce memory usage?

You can also use data structures like array from the array module for large datasets, and consider using libraries like NumPy for efficient array operations.
