When I run some python code in NetBeans, which raises an error, the output in NetBeans just gives an error message and no further information, such as line number. Is there any way to fix that?
If you can, I would run your script outside of NetBeans either with the built-in editor (IDLE) or just run it from the command line. That should give you a traceback with the error and lineno
NetBeans has issues with debugging, as other posts suggest.
added solution is debugging if don't have any compiling error

I need help in solving this problem. The screenshot below is of the code line which is giving error. It involves f-string and I am using python 3.7.6 base:conda.
This is the error message that I am getting.
This is the interpreter I am using.
Please help me solve it. Thank you.
So this issue was based on a VS Code extension that I was using to run my code. It was 'Code Runner'.
Two things need to be done:
Change this in setting.json
code-runner.executorMap": {"python":"$pythonPath $fullFileName"}
Check "run in terminal" in settings for 'code-runner'.
If you are switching virtualenv in VSCode you have to quit from opened terminal (on linux ctrl-d) and launch it again. Interpreter is not going to change without so.
This apply only to VSCode terminal obviously. And I have no idea if this is only on Linux or on other platforms too.
Hi Even i was getting the same issue see the below screenshot and and make some changes in settings.json and launch.json and then refresh it, everything will be working fine.
Error Message:
Everything works as usual in R or Python, only the Error keeps showing and it's so annoying.
Please help me to have a look at this.
Thanks!
Though not recommend running notebook server by admin, but i solved this issue with "run as admin".
you can look for more details in below link.

In order to get the stacktrace of a python program, I am trying to follow this example. In the article, the author invokes the gdb as follows. However, the python version of my environment is python 3.4.4. When I type
python3.4-dbg testmyplotlib2.py &
The error message is python3.4-dbg: command not found. What's the right way to get stacktrace by using gdb.
What OS are you on? It looks like you need to install python3.4-dbg. If you are on Linux, you will need to enter:
sudo apt-get install python3.4-dbg
GDB is excellent program for debugging, but if printing traceback is the only reason you are installing GDB, do not do it, that is waay overkill. You can just import traceback and
use traceback.format_stack() to get an array of calls that lead to the location in program
use traceback.print_stack() to print it to command line
use print traceback.format_exc() to print what lead to the current exceptions (works in except clasuse)
Using Pyhton 2.7 and Ubuntu 15.10
I faced an annoying issue when using raw_input in a python console of some IDES like ninja-ide or genay (console plugin). They cast a "EOFError: EOF when reading a line" and don't allow to write.
Meanwhile developing a *.py file, the execution is correct and don't fail. Python, as executing from terminal, doesn't fail as well as console using IDLE.
Any solution? Thanks. I couldn't find exactly this issue neither in StackOverflow nor Internet.
Whenever I start pydev/eclipse and try to run .py file I have an error:
An internal error occurred during:
"Launching PhD mainWorking.py".
java.lang.NullPointerException
When I press OK and run again everything is going how it should. The error is not very disturbing, but there is something wrong. I was trying to find what but it has no sense form me.
Anyone have similar issue or know where lies the source of the problem?
Seems like an error to me... Do you have some entry in your error log for that? (see: http://www.pydev.org/faq.html#PyDevFAQ-HowdoIReportaBUG%3F for details on how to get the contents of the error log)
