Hi there is an issue I cannot work my head around.
Basically the script works very fine when I execute it via Powershell/cmd python ./myscript.py but not when I double click on it.
I checked with a much simpler script to check if the issue was with my Windows/Python3 configuration.
import os
if __name__ == "__main__":
print('hello')
os.system("PAUSE")
And this one works either by double click or by python ./myscript.py
I guess the issue is with my script but no error is returned and it works just as expected when launched in PS so I do not get it.
Would you guys have some debugging insights?

I edited my question, hope it is described better now.
I am working on a software that gives me a nice PDF with lots of matplotlib graphics, depending on the data I get.
So think of a database of pages and then the software decides which pages are chosen and filled with changed images, The text stays the same.
So for instance for data1 I get page1-4 and page7 and page 9. For data2 I get page1-4 and page6. Saved as PDF. I am doing this manually with Quark which needs to be changed. I hope I can figure out the scripting to do so.
But for starters I cant start scribus from the developing enviroment. Eclipse Anaconda on Ubuntu.
import subprocess
subprocess.run('scribus')
works fine in terminal, but gives me an error in Eclipse which I cant figure out.
File "/home/b256/anaconda3/envs/test/lib/python3.7/site.py", line 178
file=sys.stderr)
^
SyntaxError: invalid syntax
This seems to be some Python 2 error in the site.py file
???? Is this some anaconda python path error ??
It's not really clear to me, what you want to achieve, but you're welcome to have a look at a script of mine:
https://github.com/aoloe/scribus-script-repository/blob/master/imposition/imposition.py
This is probably a bit more complex than what you are trying to achieve:
the script gets started from the terminal,
if it notices that it has not been started from inside of Scribus (the exception on import scribus)...
... it starts Scribus with itself as the Script to be run.
the script runs again, this time from inside of Scribus...
... now there is no exception when importing scribus and the body of the script runs.
Of course, it's simpler if you start a script that launches Scribus with other scripts.
For you the most important line is probably:
call(['scribus', '-g', '-py', sys.argv[0]] + arguments + ['--', file])
It's starting Scribus from Python
with as little GUI as possible (-g) and
launches the script sys.argv[0]
with a few arguments and
after the -- tells Scribus what file to open.
I have been working on a project and in the end it's suppose to print an output in a notepad file and it works perfectly in pycharm but as soon as I launch my file with python it crash every time I execute the code
I am 100% sure that the problem lies between the line I copied and pasted and I know that if start the project in pycharm with the python console setting active it work too so it may be some right problem? that's the conclusion I came with althought I'm not sure and I don't have any idea how to fix it even with my research. Ho and I,ve checked too and my python is up-to-date
number_of_product = [0,0,0,0]
Total = 0
with open("Bill.txt", "w+") as Bill:
Bill.write("{0} ChocoMilk\n".format(number_of_product[0]))
Bill.write("{0} Katkit\n".format(number_of_product[1]))
Bill.write("{0} N&N's\n".format(number_of_product[2]))
Bill.write("{0} SourJoes\n".format(number_of_product[3]))
Bill.write("Total : {0}$".format(Total))
The result should be 5 line of text written in a notepad file.
I found the problem: I was opening the Pycharm file by clicking "Open with" python3.7 and Windows wasn't giving me all the right I needed.
You need to change the basic application that runs the program from Pycharm to Python itself.
I want to open the calculator program when I type "Open calculator " . I researched a lot , but didn't get the answer I wanted.Can anyone please answer my question.
There are 2 ways to do this. One way would be access the cmd using Python which can be done by using os module. When you try to open the calculator from your command prompt, you probably type calc. Instead of manually doing this, you can have your Python code do it for you, this is how:
import os
os.system('calc')
The second way is very similar to the first one, except that this method opens another command prompt window so the window in which you're running the python code is not disturbed.
import subprocess
subprocess.Popen("calc",stdout=subprocess.DEVNULL,stderr=subprocess.DEVNULL,shell=True)
I just downloaded python on a new pc and now whenever I try to create a script the output viewer just closes down immediately when I launch it as a python file.
My original script was
import secrets
secrets.token_hex(32)
but it just closes down immediately. I thought that it was something with my code so I tried to just make the simple "hello world" script.
(print) "I hope this work"
and I had the same result as the first script, the output window opened up then immediately closed down.
I can get it to work using the python shell but I prefer doing all my coding using notepad++ and it would a real pain in the behind if I can't get that to work.
This is expected behavior if you run your scripts as you described, by opening them in Explorer. Your script completes execution in a terminal window, then closes immediately.
If you absolutely insist on running them on double click and still want to see your console, I suggest you create a .bat file at your python path with contents like this:
python -i %1
and them bind your double-click handler to use that file on .py extension. That way, Python will execute your file and go into CLI mode, preserving your terminal window and allowing you to type further commands.
My other guess would be that you want a console plugin to work right within Notepad++, in that case use nppexec: https://sourceforge.net/projects/npp-plugins/files/NppExec/
I created a Python project in Pycharm which contains multiple Python files. As of just now, I need to create a run configuration for each Python file in my project, even though they're all the exact same - with the exception of the script.
This seems unnecessary and laborious and I would love to just use one run configuration for multiple Python files.
That said, I'm a novice Python programmer just getting started and so still unfamiliar with large parts of the language.

My Run Configuration - Used for all Python files:
Some Research Carried Out
I've searched for a solution and explanation to this, but have been unable to find anything. Some of the places I've tried:
JetBrainsTV on youtube (https://www.youtube.com/watch?v=JLfd9LOdu_U)
JetBrains Website (https://www.jetbrains.com/help/pycharm/run-debug-configuration-python.html)
Stack Overflow
I hope there is sufficient detail here, if not I'd be happy to elaborate.
If those files are independent and you have nothing specific to them, then I see two simple ways of running them:
You don't have to manually create a run configuration for every file. You can just Right-Click on the file in the project tree and click "Run "
You can use the Terminal and run them files using the python interpreter as needed.
I was facing a similar situation when I started competitive programming. In my case I wanted to redirect my Test Cases from an input.txt file rather than manually typing the test cases for every run of my code. Using the above solution was not feasible, as I would need to manually change the Script Path and Redirect Input path in the Run Configuration window for every script I was running.
So what I wanted was, one run configuration, that would run all the scripts with Redirect Input path being set to input.txt.
To do that,
I created a main.py file with the following content:
import sys
if __name__ == '__main__':
fname = sys.argv[1]
exec(open(fname).read())
This main.py file is going to run my other python scripts.
Created this run configuration for the main.py file.
Now, every time I needed to run any code, with the code window open, ran this configuration, which actually executed main.py with current file name passed as its argument, which would then also take the inputs redirected from input.txt.
Hope this helps you or anyone trying to run multiple python scripts with a single run configuration in PyCharm.
