In the function you are iterating for x in df['Name1']. This will loop over every value in the Name1 column of the data frame. I think you should post your question on Code Review Stack Exchange which is more geared toward helping new programmers learn to program and write better code. — augurar 33 secs ago
This question is better suited to Code Review Stack Exchange. — augurar 7 secs ago
I did not know about code review stack exchange. Thanks for letting me know. Unfortunately, I am still not understanding how to consider the difference. Should I replace df['Name1'] with diff? — Val 45 secs ago

(1) I believe your question is too big, too ambiguous in a sense. (2) The description of the r tag even suggests "Please provide minimal and reproducible example(s) along with the desired output", and it does not appear that you've attempted to reduce the problem.

The jumping off point for exploring quantum computing is to understand that while many of the principles are counterintuitive, the classical universe we know and love is but a mere shadow of the quantum fabric of reality. To get a feel for that fundamental difference we will walk through an example that helps to illustrate the power of quantum computation.

Oh and np btw
 
Sure!
@Peilonrayz What obsolete comments? ;)
 
@pacmaninbw I'm not sure it's grammatically correct though @Peilonrayz
I think it's missing a 'be' somewhere.
Or a 'stay'
'get'

@pacmaninbw FWIW the responses you got were very SE culture. I don't think your concern of medical emergency but not dead has been answered wrt CR culture. If your family member has an account with 15/20 rep on CR your family member can 1. flag and say you're away. 2. comment in chat you're away. (Like with Phrancis) 3. If they have access to your account, message in chat you're away. (Like with Phrancis) 4. the replies you got on Meta
 
@Peilonrayz True to a big extent, one answer does mention a broken leg.

A broken leg is a quite different from ceasing to be.
On CR, any road you can think of will get the job done.

@Peilonrayz 5. Break a couple of rules and post it as a question on the main site with a 1-rep account. We'll figure out how to solve the solution from there, explicit writing rights can be provided to chat. We're talking about an extreme case here. Getting the message across (and perhaps more importantly, knowing up front the message will get across) is a bit more important than bureaucracy. @pacmaninbw

When I suggested moving the question to MSE, I didn't realize it was going to be this personal.
 
@Mast The second answer was somewhat less than understanding about just how often accidental death can occur.
 
8:00 PM
@pacmaninbw Yes.
I've carried too many people to their graves (some literally) to presume any human can tell when another human will likely pass away.
They keep beating the odds, both positively and negatively.
 
Sorry for your losses. I have literally carried some people to their graves as well.
When my father died my mother was supposed to be the one to check that the correct body was in the coffin. I had to end up doing that because mom was late to the funeral.
 
@Mast cc @Peilonrayz @pacmaninbw Another solution which I have personally used in the past is to put what message you want to pass on into a site like pastebin.com (from experience I know that unfortunately the rate limiting system isn't a big fan of new accounts/IP's posting long bits of text as a suggested edit), get a link and then post a short message saying who you are and a link in a suggested edit in a mods post.
Even if the mod isn't online and reviewers ignore it the mod will still get a notification and can take relevant action.
 
Oh nice, another 1rep solution
 
Not sure about code review, since this seems to be a design review question, not a code review question. Maybe Computer Science. In any case, it looks fine to me, except for the header guard at the top. Defining a generic word like hash, and replacing it with nothing, will almost certainly drive your users crazy. Use something that won't cause trouble, like HASH_Huser3386109 35 secs ago

@CaptainObvious it sounds like this OP didn't read the links I included in my auto-comment:
Thank you Sam. I don't get it.. isn't this site purpose supposed to be for reviewing code as the url states? .. The title of the questions describes exactly what I wish.. For someone to review the code and make some recommendations or suggestions for improvement.. — Gass 1 hour ago
Hopefully they will read and understand my response:
Yes the purpose of the site is reviewing code. However, as I mentioned before, the standard is for the title to describe what the code does. The majority of posts on this site are about improving code so if we all had titles about code review then it would be difficult to distinguish between them. I changed the title accordingly. Feel free to edit and give it a different title if there is something more appropriate to describe what the code does. — Sᴀᴍ Onᴇᴌᴀ 4 mins ago
 
@SᴀᴍOnᴇᴌᴀ FWIW I've had similar before. I now just edit the title, because explaining is more time consuming than just editing.

@pacmaninbw An idea just popped into my head. What do you think of using the edit's "edit summary" rather than a comment?
 
@Peilonrayz I do both
e.g. Rev 2 of that post I updated earlier
 
Sorry, my brain's a bit fried today; I'm currently not seeing reasons to do both. Why do you do both?
 
The auto-comment (which I could add as a mac keyboard shortcut) and browser form field history suggestion make it easy
 
@Peilonrayz Leaving a comment will definitely ping the user, and will make others aware if they make the same error.
 
9:50 PM
some users might not notice the revision commeent
while they would receive a ping about the update, they might just skip to the changed section
 
Interesting. Thank you both. I think I'll definitely try to change edit summaries to include a short 'title autocomment'. And I think I'll post comments for users with 2+ posts.
 
10:19 PM
@CaptainObvious I left a comment asking the OP to post in English
It sounds like it might not be ready for review?

Does that translate to "...However, I now have the problem that I just can't get my entity collision right"?

I'm still suspicious that the code doesn't work as intended - the linked java file has the method (that is embedded in the post) commented out
