# Write an action using print
print("Debug messages...", file=sys.stderr)

print(result)

Please help i can’t find problem in code (it is in python 3)

#782

Insert after the first “for”

print(tpos,file=sys.stderr)
print(tneg,file=sys.stderr)

After i think that you’ll easily find where is the problem 
 :wink:

#784

Am i even on the right path?
please help

The problem appears to be that you’re using tpos = [t] and tneg = [t], on lines 18 and 20 respectively, which isn’t actually appending the lists.

#786

please help me
i’m lost

#787

line 14 doesn’t make sense

#788

you wrote this :
t = int(i)
if x < t :
tpos = [t]
elif x > t :
tneg = [t]

instade of it you can write this :

t = int(i)
if x < t :
    tpos.append(t)
elif x > t :
    tneg.append(t)

An error occurred (#73): “Only 1 executor running at the same time for a test session”. What can i do?

#790

We’ve just solved the issue. If you try again, it should work fine. Sorry about this!

#791

I don’t know why my variable is not always responding to my if test.
I’m trying to solve in java script and have written this code after the code provided initialy:

let posT=5526, negT= -273, T=null; 


for (let i = 0; i < n; i++) {
    if (inputs[i]>=0 && inputs[i] < posT) {posT=inputs[i]}
    if (inputs[i]<0 && inputs[i] > negT) {negT=inputs[i]}
    console.error(posT);
}

if (posT <= -negT) {T=posT}
else if (posT > -negT) {T=negT}

console.error(".");

console.log(T);

console.error(".");
for (let i = 0; i < n; i++) {console.error(inputs[i])}
console.error(".");
console.error(posT);
console.error(negT);

and this is my console output:

I was expecting my posT variable to be 5 at i=1 on the for loop, but it’s not working,but it does works for some other values. That also happens with negT on other tests

#792

already found it, the input given were strings instead of numbers, so the comparison was bugged. Solved it with a few changes to get 100% score

#794

you fail these two validators:

Does your code manage when there is only one temperature in input (for example, -273 or 2256) ?

#795

Oh now I get it thanks for the help

#796

I’ll take it back I don’t understand it, can you explain it to me in more detail?

#797

if I give only 1 temperature to your code in input, what does it return?

#798

It outputs the entered temperature

#799

not for all temperatures it seems :slight_smile:

#800

Oh now I see the mistake 

Well now I know why it doesn’t work. but I have an idea, let’s see if anything changes.

#801

Hey, i am very grateful for your help.
Without you, I really wouldn’t have got the 100% score.
Thank you
