Anyone who have worked with text analytics and know how to get tf-idf when you're given data represented in sparse matrix (numerically) instead of actual data? 
I'm stuck with a problem and would appreciate expert advise or any help

... And the message is back again.

This was not a programming problem rather a research approach that I wanted to discuss. Otherwise I would have asked in the other section.

I don't remember you ever replying to any of my posts neither did I asked this question before. If it's that's annoying to you please consider not replying at all.

I've already found the solution but unable to delete this post now. Thanks for bearing

I was just about to reply to a message with "It sounds like you're looking for BM25F, but if you work for google, just stay at home and do no work evil", and I get a message saying the message (the first one, not my one or the one I just got) is not available.
It must be that fast because of SSDs and the new "commandeer your graphic chip's processing power" stuff.
I'm having trouble recalling which buzzbollocks ideas are most popular, at the moment, so feel free to point out the ones I've missed.

Hey! What about dad's basement? I'm an equal opportunity nerd! Besides that, I have had my own basement for a while and going home to mom, or getting any substitute, would be the worst fate I could think of.
I have lived with several Zen masters - all of them were cats.

There's something wrong with that picture. The developer looks showered and dressed.

[Verse 1]
Behind the glass I watched the world
From cracks the blinds make when they're drawn
I watched the world for years this way
And that catches us up to this moment today
[Chorus]
Quarantine
The rock and the hard place I'm between
Quarantine
Quarantine
Quarantine
[Verse 2]
Oh, and it was you I did this for
I put the deadbolt on the door
Understand, I can't see you now
Realize it's not to keep me in
But to keep all the sickies out
[Chorus]
Quarantine
Such an ugly word for what I mean
Quarantine
Quarantine
Quarantine
Oh
[Bridge]
I heard you let some little flea
Give you that contagious disease
You let him climb right on you two
And it's been plaguing me, too
La-la-la-la, la-la-la-la
La-la-la-la, la-la-la-la
Realize it's not to keep me in
But to keep all the sickies out
[Chorus]
Quarantine
A rock and a hard place I'm between
Quarantine
Quarantine
Quarantine
Quarantine
Quarantine
Quarantine
Quarantine
Oh

The assignment is to write a function that returns the number of prime numbers that exist up to and including a given number. The solution is below but I'm having trouble interpreting it. The part I don't understand is the 'for y in range(3,x,2)' loop. The first time it runs, x = 3 so I see it as 'range(3,3,2) but this doesn't make sense because the middle number represents up to but not including. So a range of 3-2 doesn't make sense. Also why is 'else:' not lined up with 'if'?
def count_primes2(num):
primes = [2]
x = 3
if num < 2:
return 0
while x <= num:
for y in primes: # use the primes list!
if x%y == 0:
x += 2
break
else:
primes.append(x)
x += 2
print(primes)
return len(primes)

No snakes in the lounge!
There are ophidiophobics here, and they will not be polite to you.
The first thing you need to do, is: learn to read the red writing at the top of the page. Then post here: Ask a Question[^]
You will not make yourself at all popular if you just decide that rules do not apply to you - and when you want free help from people annoying them isn't a good idea.
The first thing I'd do is dump the Snake course, and find a real language to learn ...

Do you realize there is no 'range' in the posted code?

1. Wrong forum, try "Questions".
2. Check the red text at the top of this page.
3. Learn a proper language, dup the snake.
4. Get a haircut! ...in a few weeks, after COVID-19.

After a four-year hiatus I have decided I want to play music again and I have joined a band. This is probably very bad timing since most of the places we will likely play have been ordered to shut down. I guess we will have plenty of time to rehearse.
Anyway, tonight is the first rehearsal following the (successful) audition. A little while ago the guitar player sent me an e-mail about learning another song that wasn't on the list. It's by The Police and it's called, "Don't Stand So Close To Me." For these days, I can't think of a more topical song than that.
-edit- it has morphed into an extended medley and maybe a whole set. We'll also play "Keep Your Hands To Yourself" by the Georgia Satellites.
Can you think of any other songs on the topic?

I play the bass primarily, and guitar and keys also. We switch around a bit. It's a lot of fun.

Ditto.
And, coincidentally, I just ordered new strings (Rotosound flat wound), some blank nuts, and a maintenance kit for guitars. The bass (Musima Action 2001) has been sitting there since the DDR dissolved.
And I tore apart my amp trying to track down the intermittent no-sound problem. I *think* it's one of the pots.

I used to play the chainsaw in a band.
It opened a lot of doors for me.

I used to play the triangle in a death-core band; but I quit, that was exhausting.
