Error In just the printing statement

Question

Error In just the printing statement

inst-cicada opened this issue 4 years ago · 72 comments

Expected: StringContaining "[3] find needle in the haystack
[2] water the plants
[1] the thing i need to do
"
Received: "[3] find needle in the haystack·
[2] water the plants·
[1] the thing i need to do·
"

I tried to put \n, different print(), and also tried tripple quoted strings but I dont know from where that (·)dot comes when I test the code with npm test. While testing with my powershell everything is fine with no dots but with npm test there is dots. Please help.

Answer 1 · 2020-12-17T06:49:00.000Z

@inst-cicada Could you check for trailing spaces in your output? It's likely that the dot character is being used to indicate additional spaces at the end of the line in your output.

The test doesn't handle additional spaces within the output lines, at the moment.

Answer 2 · 2020-12-17T14:09:36.000Z

The same error persists in my system too. I'm using python and regardless of whatever is done, regex, strip, split, join; nothing works. Removing whitespace, newlines, others, nothing is working.
What is to be done?

Answer 3 · 2020-12-17T14:21:06.000Z

I'm having the same issue, where that (·)dot comes when I test the code with npm test with Python

I'm not a specialist but I think its becz windows uses Windows-1252 and npm tests are converting text to utf-8. on Top of that (again i think) python by default uses system encoder "Windows-1252" on Windows and after python 2.0 there is no easy option to change encoding (or I'm unable to find) so that "\n" (Windows-1252) is converted to (·) utf-8 still not sure

and python3 should be replaced with python in todo.bat to make it run on Windows other wise it gives "Python Not Found!"

I tried my code on Ubuntu (linux) and it works without any problem 👍

EDIT:
found a solution for Python on Windows

instead of print(string_variable) try sys.stdout.buffer.write(string_variable.encode('utf8')) and don't forget to import sys to print to console, (where String_variable is ur variable name)

Hope helps :-)

Answer 4 · 2020-12-17T14:29:40.000Z

Yeah, I'll try doing that. Thanks a lot @MrAdiii!

Answer 6 · 2020-12-17T16:31:27.000Z

I am using Cpp, can you tell me the solution for dot problem ???

Try on Linux, running on Ubuntu fix the problem for me in Python

Answer 7 · 2020-12-17T16:43:13.000Z

I am using Cpp, can you tell me the solution for dot problem ???

Yeah @MrAdiii is right, try linux. If you dont have a linux operating sys, try using one with the help of VMWare.

One more workaround discovered was that in python using the print statement with end in no spaces as print(text,end='') also works. Since python by default has end='\n', changing it to '' would help.

Answer 8 · 2020-12-18T00:59:01.000Z

The issue was with your directory path which contains space in the folder names and child_process package couldn't able to resolve it.
This problem occurred due to the test cases which didn't handled this error.

As others said, its due to space in the path name. So here's how you can fix it (it worked for me):
In the todo.test.js, replace the line let todoTxtCli = (...args) => [`${__dirname}/todo`, ...args].join(" "); with this let todoTxtCli = (...args) => [`"${__dirname}"\todo`, ...args].join(" ");

This will tell the cmd that the space encountered is a part of the path and it wont end there. Hope this helps.

I think there is no proper answer to this for C++ , either code in pyhton or check in Linux, I struggled with the same problem , I think maybe our cases will pass in their server even when they are not passing for us( because we are using windows which does not uses utf8 encoding ) , just focus on getting the content right and pass the rest of the test parts. Tests can pass in their server because the dot(.) will not be inserted there( I guess );

Hey, If someone has completed the app. can you share the source code?

Answer 71 · 2021-01-04T16:27:24.000Z

@samarthshiramshetty Please see the README of the repo:

Kindly desist from sharing your solution privately or publicly. This is because the programming task is not complex for those who've written non-trivial amount of code before. But for beginners, solving this can be quite instructive - frustrating at times, but rewarding in the end.

But if you share your solution with them - through a GitHub repo, or by circulating in your private networks, you're only robbing them of a rewarding experience that would have helped them grow as programmers.

It is trivial to detect copy-cat code submissions and students who submit plagiarized code will be unable to find a place among the limited seats in the course. It is just that it'll take us a few more moments to read through the code and tag it. A lose-lose proposition for all concerned.
