I wish I could use python to execute the Excel macro, so I tried to use the package xlwings to implement it.
The OS of my laptop is macOS Catalina (ver.: 10.15.7), my compiler is PyCharm (ver.: 2021.2.3), my Python version is 3.8.8, I used Anaconda (Ver.: 22.11.1) as my interpreter, my excel version is 16.66.1 (Microsoft Excel for Mac).
I faced the error "Command Error -1743: The User has declined permission" when I tried to use this package originally, and I solved this issue by installing an old compiler & using the old version of the compiler to run my code. My privacy setting for automation in the app Setting was shown below: (This is NOT the question I want to ask, but I'm not sure if it is also related to the issue I faced, so I still attached it here. I had uninstalled the old version of my compiler already.)
I wish I could implement an existing macro (called Hi) in an existing Excel file (called [StakeOverflow]HelloWorld.xlsm) through Python (represented as MY_PYTHON_FILE.py below), like the snapshot below:
My Excel file and my python code were stored on OneDrive. My macro code was shown below:
Sub Hi()
MsgBox "Good morning!"
End Sub
My python code was shown below:
import xlwings as xw
import time
wb = xw.Book('/Users/<MY NAME>/OneDrive/MY PATH DETAILS/[StakeOverflow]HelloWorld.xlsm')
time.sleep(10)
app = wb.app
macro_vba = app.macro("Hi")
macro_vba()
The code looks really simple, but I still faced the error. My Excel was not opened automatically, and I even could not open the Excel file manually thereafter. The error was shown below:

Process finished with exit code 1
I tried to use terminal to run my python code, but I could not solve the problem, either.
I tried to open the Excel file manually thereafter, the error was shown below:
Excel cannot open the file ’[StakeOverflow]HelloWorld.xlsm’
because the file format or file extension is not valid. Verify
that the file has not been corrupted and that the file
extension matches the format of the file.
I tried to Google this error, but few solutions was found. It seems that it is related to the issue of external storage location. I tried to create another Excel file with the same name & macro code on my desktop and try again, and the error would disappear. (However, our company stored the files on OneDrive, so I wish I could utilise the file online.)
Just wondering if anyone here faced this situation before?
I found the answer by myself today. The issue is related to the naming issue rather than the permission issue.
As we could see that the error is KeyError: '[stakeoverflow] helloworld.xlsm', which implies that the problem is here. (Maybe because the system could not find the Excel file with this name.)
I tried to change the name from [stakeoverflow] helloworld.xlsm to helloworld.xlsm, and the error was gone. It seems that when xlwings want to open an Excel file, it would check the validity of the file name and change the name into smaller cases. If the file name contains special characters which are not allowed (e.g., "[]"), then the error would occur.
Notice that I could store the Excel file with these special characters in our laptop & OneDrive, but xlwings did not accept them.
Hope it is helpful to those who face this issue when using xlwings!
I am deploying a web server, and after I finish compiling.There are the executing documents;
01client.c client epoll_server.c server
Then I try to run server
./server
There is an error which I cant fix it. I have search ways for solving but still can't fix it.
load error: No such file or directory
Maybe some one can help me,please!
Thanks a lot!!!!
System utilities print the program generating the error at the beginning of the line followed by other useful information such as the name of the missing file, so this is probably an error from a user program. I can duplicate the error as follows:
errno = 2;
perror("load error");
which prints:
load error: No such file or directory
Look for the perror line in the server code. If it isn't clear what file it can't find, print the string from the failed command it is reporting.
I am using Django to display my code in an html format using class based views. My code reads a log file and displays stats based on what is in there. When I try to access the log file from my computer this error message is displayed:
[Errno 13] Permission denied: 'C:/Users/bhattaar/Downloads/access.log'
I first tried going through the properties of the folder to make sure everything was set to read only (which it already was) and then I tried running the command prompt as an administrator and it still would not work.
The line the error appears on is this:
log = open('C:/Users/bhattaar/Downloads/access.log', 'r')
Does anyone know how I can resolve this issue?
Does this work?
Taken from here
log_file = r'C:/Users/bhattaar/Downloads/access.log'
with open(log_file) as f:
f = f.readlines()
The program should allow to run several https get requests with one aiohttp.ClientSession as the documentation suggests. It is intended to run a telegram bot.
I was not able to catch the exception with try ... except. Therefore the program hangs when exiting. During extended sessions the error is printed in the command windows (but not in the error log).

As the error information is very unspecific I could not really isolate the source and have a short code to reproduce the error.
A sample code is on github under https://github.com/fhag/telegram2.git
In order to run the code you will need an API token from telegram of your own bot.
This error showed up the first time when I upgraded to python 3.7.1.
Python is running on Windows 10.
I got a fatal error at auto_load function. See the following error, indicating that the specific directory and file '/mnt/webDir/www/sossage/system/classes/kohna/log.php' file failed opening required. Yes, file doesn't exist. Its's wrong path.
But, I never write the code, also can't find anywhere using 'find' option on my web root.

How can I solve the problem, please let me know the solution or tips.
Thanks.
You've got a typo in your configuration, likely. Note the directory it's attempting to access:
...system/classes/kohna/log.php
"kohna" is not the appropriate spelling. The directory is instead:
...system/classes/kohana/
