How does deferred execution work in Python?

Can you explain what deferred execution means in Python?

Deferred execution in Python refers to the concept where the evaluation of an expression is delayed until its value is actually needed.

How does this relate to generators?

Generators in Python utilize deferred execution by yielding values one at a time, allowing for efficient memory usage.

Can you give me an example of 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, executing only when requested.

What are the benefits of using deferred execution?

The benefits include improved performance, reduced memory consumption, and the ability to work with large datasets efficiently.
