"/../Playground/" unexpected in code

Question

I was looking at one of my old codes (https://code.sololearn.com/cwm94X98fI1X/?ref=app) and decided to change the "sep" variable to "/" just to see what would happen.

And instead of each letter being separated by a slash, which is what would happen with any other character, the output replaces the letters with "/../Playground/"!

What’s going on??

Answer 1

Hi McInventor29, for some reason, the SoloLearn python code playground is giving an error of ".../Playground/" whenever we try to print or concatenate any form of these patterns:
print('/E/L/E') # O/P: .../Playground/
print('/a/b/c') # O/P: .../Playground/

I tried to run your in other platform it's working super fine even with sep='/' (I use Dcoder to run and it's works fine)

Maybe, the ".../Playground/" error is because SoloLearn interpretation uses/works on some other server/web interpretator(and not on a real environment).
And for some reason "/a/b/c" happens to be some kind of the file path(oh no, something very related which IDK) basically some fault in their system coding maybe.
who knows?

So, basically this is a BUG in SoloLearn code playground, I think so!

Answer 2

I tried my best! 😂
That was the perfect example I could ever come!
Anyway, it's weird!

Answer 3

Rohit That makes sense... except for "/a/b/c" being a file path.😂

Anyways, thanks!

Running this in Python also outputs "stor../Playground//"
print("stor/elec/bio/med/")
so this bug is probably affecting output from all types of Sololearn Playground codes.

If that is done to prevent us from seeing file paths, that would be ineffective because I printed your string anyway. If it had some secret, you could see the original value anyway.

I experimented with the code and commented my findings here:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
string what = "stor/elec/bio/med/";//I type this

// The following loop outputs: s t o r / e l e c / b i o / m e d /..
foreach (char c in what) {
Console.Write(" " + c);
}
Console.WriteLine("..");
Console.WriteLine(what);//it outputs stor../Playground//
Console.WriteLine("elec/bio/med/");//it outputs elec/bio/med/
Console.WriteLine("/elec/bio/med/");//it outputs ../Playground//
Console.WriteLine("/hello/world/hi/");//it outputs ../Playground//
Console.WriteLine("stor/elec/bio/med/");//it outputs stor../Playground//
Console.WriteLine("stor/" + "elec/bio/med/");//it outputs stor../Playground//
Console.Write("stor/"); // it outputs stor
Console.Write("elec/bio/med/");//it outputs ../Playground//
Console.WriteLine("----");
Console.WriteLine(what.Contains("Playground"));//it denies it's existance
Console.WriteLine(what.Contains("bio"));//it still believes the og value is true
}
}
}

Josh Greig Yeah... this is definitely weird.
