Fix needless operation

[Manvi-Agrawal]

fixes #1585.

I would prefer to limit this PR to operation -> function replacements only. Maybe with additional change to the output strings. I'd prefer other questions not in code comments, but rather in a GitHub issue. @swernli, what do you think?

Yes, I agree. The questions in the comments can be removed and the PR focused on cleaning up the existing samples. We've had some debates about reducing some redundant samples, but this PR doesn't seem like the right time to take that on. @Manvi-Agrawal you are definitely asking the right questions though!

[DmitryVasilevsky]

Please leave only operation -> function changes and output string improvements. Open issues for questions instead of adding comments (or add to existing ones).

Hi @DmitryVasilevsky and @swernli, created 2 separate issues for my questions : #1708 and #1709 . Could you please take a look at this PR?

[swernli]

Thanks for splitting the general samples clean up into separate issues. The focused changes here look good!
