Yield statement question

[DPaul]

I have been reading up on the "yield" instead of "return" statement.
Arguably, I understand what it does.

On most sites however, they give the generic(?) example of how to
print the squares of the numbers from 1 to 10 using a def function with a while loop etc..
They need 10 lines of code for that yield example (even taking out the comment lines)
Anybody can print those squares in 2, let alone 1 line of code.

Question: could somebody describe - in words only - a situation where using "yield"
provides a huge benefit?

thx,
Paul
