As a part of some automation I am trying to connect to mainframe using python, where I can access the mainframe files and create a
report. Just like using mainframe files as DB for python program.
To login to mainframe - we need to provide host details(xyz.host.com)
followed with region details(h123p) and then with our credentials.
I found that we can do this using python package py3270 and tried doing it but getting the error.
from py3270 import Emulator
# or not (uses s3270)
em = Emulator()
em.connect('xyx.example.com')
em.fill_field(3, 1, 'xxxx',5)
em.send_enter()
em.fill_field(2, 1, 'xxxxxxx', 7)
em.send_enter()
em.fill_field(8, 20, 'xxxxxxxx', 8)
em.send_enter()
# if your host unlocks the keyboard before truly being ready you can use:
em.wait_for_field()
# maybe look for a status message
if not em.string_found(1, 2, 'login succesful'):
abort()
# do something useful
# disconnect from host and kill subprocess
em.terminate()
The error:

Based on the error messages you're seeing, I suspect you're having a problem with missing/not found x3270/s3270 libraries.

The above suggests that the library is trying to start Ws3270, the windows version of x3270, and is unable to do so.
Make sure the the required libraries are in your path and visible from python.

Looks like the default permissions for that command aren't enough to create a process of Inkscape, but I'm already using the command line with administrator privileges.
I was able to convert a notebook to PDF successfully past year, it's the same machine but I was using another version of Python, 3.6 or 3.7, does that have to do to with this?
I reported this issue here https://github.com/jupyter/nbconvert/issues/1525
My temporary solution was to use the absolute path as a string literal where I installed Inkscape instead of calling self.inkscape, in my case the path is 'C:\\Program Files\\Inkscape\\inkscape.exe':
https://github.com/jupyter/nbconvert/blob/88baf7a9ca724d74c9f890a60d5c3680e8959a14/nbconvert/preprocessors/svg2pdf.py#L57
in that line I have p = subprocess.Popen(['C:\\Program Files\\Inkscape\\inkscape.exe', '--version'].
I printed self.inkscape and the output was 'C:\Program Files\Inkscape\inkscape.exe'. I thought it was because of the double back slash so I tried os.path.abspath(self.inkscape) but it was adding the current path from where I'm calling the command at the beginning. I also tried pathlib.Path(self.inkscape) but it didn't work, so I have no idea what the problem could be.
I am developing a small usb application using python (pyUSB) under Win 10 and have the following problem.
When I test basic commands under the python console, everything works fine. I can open the device, write bytes to it and read from it.

what's wrong? I know that file is there. I checked it using os.path.isfile and subprocess call
Other things that I tried:
-added full image file path using string literal 'r'
-tried different images and file types
I want to create an experiment with Psychopy in which I will present randomly video that participant will have to evaluate.
I have created a routine with my MovieStim and my Rating response and a Loop with my conditions file (in which are my video files videoname.wmv).
All my videos are in the same folder as my experiment.
I have specified the MovieStim with a variable refering to my Loop's column ($Stimulus).
But when I run the experiment I have this message.

It seems to be something wrong with the ffmpeg executable but I don't understand what.
Do you have any idea ?
Thank you very much fo advance !
Have a nice day.

I developed an appengine application in GO and now I tried to use the androidpublisher api. For this I need many dependencies like:
github.com/google/google-api-go-client
github.com/golang/oauth2
google.golang.org/appengine
google.golang.org/appengine/urlfetch
I tried to setup oauth2 authentication for google-api-go-client according to the example in https://github.com/golang/oauth2
Everything looks fine but I can't run the app-server anymore on my windows development machine. It complains about too long filenames:

I think my GOPATH is set up wrong so he gives all gofiles as argument to go-app-builder.exe.
My project is under C:\Users\me\project\ that's where the gopath points to and were I'm standing when I type:
goapp.bat serve .
Can someone help to fix this problem? Thank you.
EDIT
My project structure is like this:
How should i set my GOPATH?
GOPATH
$GOPATH
app.yaml
cron.yaml
pkg
src
testapp
app.go
golang.org
x
oauth2
Edit 2
I tried to move my GOPATH to project-root-dir/gopath but now i get this error message:

I solved the problem by setting my GOPATH.
It's set now like this:
GOPATH=C:\Users\me\development\appengine\gopath;C:\Users\me\project
Now everything works find and the uploaded file is much smaller now. 2MB vs. 11MB.
Thanks for the tip.
