I am a newbie to py.test , Please let me know how to run the py.test in PyScripter Editor.
I have tried in the belwo way but it doesn't work.
import pytest
def func(x):
return x + 1
def test_answer():
assert func(3) == 5
pytest.main()
and on running the above script i get an error saying

Pleae do help me
The script appears to be wrong , as far as i know pytest.main can be used if you want your pytest should be run by python interpreter. You need have have your test under a directory.
For example your pytest file is called test_sample which has following content
===================================pytests/test_sample===============================
import pytest
def func(x): return x + 1
def test_answer(): assert func(3) == 5
==================================================================================
Then you can have the following code in python file which runs your test_sample
pytest.main(args=['-s', os.path.abspath('pytests')])
This should solve your problem
If you dont want python to run your pytests you can configure pyscripter runner to be run by pytests via tools-->configure tools and then add the pytests command line argument. you can then run you pytest from tools. By default pyscripter uses python interpreter as runner
You can use pytest in pydev :
http://pypi.python.org/pypi/pytest-pydev/0.1
Seems like PyScripter sets some sys.stdout stream that pytest does not recognize. I just tried to refine the handling from pytest's side. You can try using it with:
pip install -i http://pypi.testrun.org -U pytest
which should in particular install also the "py" lib which contains the TerminalWriting code. If that doesn't work, please file an file with the exact environment/PyScripter version you are using. And also the value of "import py ; print py.version".
HTH,
holger
import pytest,os
os.chdir("C:\Users\Public\Documents\Development\Python\<test_pytest.py>") #your file location
pytest.main(['-s', 'test_pytest.py'])
save the file . On Pyscripter go to Run-->Python Engine--> Internal
Run the test , it should work.
Somtime pyscripter doesn't pick up the change, you may have to reinitialise the python engine (Ctrl+F2)

I was forced into some software updates on my laptop (ThinkPad) and after the update when I tried to open Spyder (via Anaconda) and it won't open. I don't have any experience in errors like this or fixing this stuff (and I am aware this may be something that is super simple). Please help. This is the application launch error I am getting:

Thanks,

Did you try to run spyder on the terminal?
It should be prebuild in Anaconda.
Your Spyder config file should contain but is missing 'custom-1/background' in section: 'appearance'. If you have no experience, the easiest thing for you to do is uninstall and install Spyder (via Anaconda). Your other option is to find the config file called in line 513 of C:\Users\cyrra\anaconda3\lib\site-packages\spyder\config\user.py". Then open the config file (if it exists) and correct it. If the file is not found, search for that config file and place it in the expected location.
I'm trying to run flake8 on a docker django built like described here (tutorial page)

Does anyone know how to solve this?
Additional Data:

Thanks for helping!
If you don't care for flake8, then just delete that line. It will work. I had the same problem.
I know this isn't an answer. I would add a comment instead if I could.
I encountered a very similar error profile when I had refactored and left a lot of data which formerly had been in the top of the project down in what became the package folder. There were 33621 files including .venv, .nox, .pytest_cache, .coverage.
File "/usr/lib/python3.8/multiprocessing/pool.py", line 448, in <genexpr>
return (item for chunk in result for item in chunk)

IndexError: string index out of range
If you see a similar signature (the parallel processing engine being overwhelmed in some way and throwing an exception), you may want to review your project directory structure and make sure that you did not put this kind of data in your sources directories.
I'm using Python Tools for Visual Studio with py.test. I'm able to use pytest fine if I run the script without debugging, but when I run with debugging, the script crashes. Below is my code and the output that I get in the console window. I've searched for Google for answers but I've come up with nothing that solves this issue; it seems like no one has had this exact problem before. I'm running Visual Studio 2013, with PTVS 2.1 VS 2013.

AttributeError: '_DebuggerOutput' object has no attribute 'closed'
Q: How can this error be resolved so that I can debug from inside Visual Studio?
It's a bug in PTVS that has been fixed for the upcoming 2.2 release.
There's no build with the fix yet, but you can just apply it yourself, as it is in a .py file and does not require recompilation. The file that you need is:
C:\Users\...\AppData\Local\Microsoft\VisualStudio\12.0Exp\Extensions\Microsoft\Python Tools for Visual Studio\2.1\visualstudio_py_debugger.py
Find class _DebuggerOutput in it, and add the following at the end of it:
def __getattr__(self, name):
return getattr(self.old_out, name)
I'm trying to import GTK in Ubuntu Python 2.7, and I get the following error. PyGTK imports just fine. When I import gtk, I get the following error:

TypeError: idle_formatwarning() got an unexpected keyword argument 'file'
How do I fix this?
This is a bug in idle. Looking at the last line of that error message:
File "/usr/lib/python2.7/idlelib/PyShell.py", line 64, in idle_showwarning
lineno, file=file, line=line))
TypeError: idle_formatwarning() got an unexpected keyword argument 'file'
This is saying that the warning.idle_showwarning method does not have an argument "file".
Sure enough looking at /usr/lib/python2.7/warnings.py
def formatwarning(message, category, filename, lineno, line=None)
There is no such argument.
This apparently has been resolved in source control but I do not think it has made it into a release yet. I would just hack the /usr/lib/python2.7/idlelib/PyShell.py file and remove the offending argument from line 64.
Then try it again...
Try it outside of IDLE. The error here is in IDLE, not your code.
Create a new script that contains import gtk and save it anywhere.
From the command line, in the directory where your script is located, run python whatever_your_scripts_name_is.py.
See if you get an error. You may not be able to import gtk in IDLE.
Edit: There is apparently a problem with GTK and IDLE in some situations on Ubuntu.
Try a different Python shell; I'd recommend IPython which you can install with Synaptic or sudo apt-get install ipython.

Could someone point me in the right direction, or towards some material that may help me troubleshoot the issue? Thanks!
Disable yum-fastermirror and you should be able to complete the install.
yum --disableplugin=fastestmirror update
Are you on a virtual machine?
