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.
