Update timeit.rst

Clarifying that Tim's introduction to "Algorithms" is only in the second edition of "Python Cookbook" (since, alas, it's not in the current, third edition).

Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept this contribution by verifying everyone involved has signed the PSF contributor agreement (CLA).

Recognized GitHub username

We couldn't find a bugs.python.org (b.p.o) account corresponding to the following GitHub usernames:

@alex-martelli

This might be simply due to a missing "GitHub Name" entry in one's b.p.o account settings. This is necessary for legal reasons before we can look at this contribution. Please follow the steps outlined in the CPython devguide to rectify this issue.

You can check yourself to see if the CLA has been received.

Thanks again for the contribution, we look forward to reviewing it!

Patches go to master branch to be backported back to the relevant branches. Please see https://devguide.python.org/pullrequest/

Sorry, it looked like a good idea at the time.

[ned-deily]

Since the PR was originally (incorrectly) against the 3.8 branch, it's probably easier and safer to just cherry-pick the change to a new PR against main and auto back port to 3.10 and 3.9 now and close this PR.

[iritkatriel]

There's still the CLA not signed issue as well.

And I haven't checked the book myself to verify this change.

As a core developer, it looks like Alex does have a signed contributor agreement from way back but it is associated on bpo with a different GitHub name, @aleaxit. The bpo entry could be changed to link to @alex-martelli; AFAIK, it's only possible for a bpo user to be associated with one GitHub account. It's a bit of a nit, of course. Alex, any preference?

[gvanrossum]

Someone should at least ask Alex if this is him. Anybody can create a GitHub account named Alex Martelli and add a photo of Alex to it... (And IIRC GitHub frowns upon people having multiple accounts.)

CLA is not needed for such a trivial commit, especially a data correction.
Since 1st edition did not have Tim's intro, 'the second edition' should have been there from the start,
and would be true now regardless of 3rd edition.
The current doc can be edited in main without cherry-pick.
I asked on python-list for any 3rd edition owners to verify the deletion.

18. Algorithms with Tim's intro is now 1. Data Structures and Algorithms, without. Half of Tim's 4 1/2 pages discussed classic algorithm references; the other half timeit, with bits dated. I looked through the doc chapter to see if there was anything really essential missing and decided not. Specify Python Cookbook edition for reference #26301 replaces this.

Irit, thank you for trolling through 'stale' PRs like this so we can try to dispose of them one way or another. In the future, you can ask me to help without the accidental mass review request ;-).
