What are Python generators and why are they useful?
In python programming online, generators are widely used because they allow you to iterate over large datasets without storing everything in memory. This makes them extremely efficient for real-world applications where memory optimization is crucial.
They use yield to produce values one at a time:
def counter(n):
for i in range(n):
yield i
Generators improve performance for data streams, processing large files, real-time pipelines, and situations where loading the entire dataset at once would slow down your program.
