I converted my Python code into an executable using pyinstaller but part of my project involves printing the result onto a text document, stored on the computer. However this same code doesn't work once in the executable. I separately also tried to get it to just create files using the
with open(f'{random.random()}.txt', 'x') as sys.stdout:
print(encmsg)
option and using a random num generator to create new file names so it doesn't overlap. Still didn't create anything.
In Summary,
What code, when running through an executable file, will download the string it produces onto a text file onto the computer SOMEWHERE.
Thank you.
The relevant code is:
string = '1219151'
with open(f'{random.random()}.txt', 'x') as sys.stdout:
print(string)
That is it. It's in an executable, but doesn't produce the txt file anywhere.
I am on Windows 10.

When I try to write something, such as variables, the code is renamed to the file name on the computer.
For example, if I write:
a = 20
f = 15
print(a+f)
then the code file will automatically be renamed to the first line, i.e. "a = 20"
Then, when I try to run the code, the program outputs nothing but "Python" and some incomprehensible words.
What could it be related to?

I installed the latest version of Visual Stuio Code with Python, they are new, so there should be no problems. But this time it went wrong.
After reinstalling the program, the problem remains.
First of all, if there is no special requirement, please do not use Code Runner to run the script, using the official extension Python is a better choice.
In addition, the dot on your file label means that you have not saved the file, you can add the following setting to enable automatic saving in the settings.
"files.autoSave": "afterDelay",
You may have created the file using the following method. File --> New File... --> Python File. At this time, the file has not been named, also not saved. You can see that there is no such file in the resource manager list at this time.
So the file label shows the first line of codes. This is a feature of vscode, you can refer to this link. And because the file has not been saved, there will be problems executing the script.
You can rename the script file directly (F2), or vscode will remind you to name the file when saving. Another way to create a file is to right click and choose New File..., enter filename and end with .py extension.
I am trying to replicate another researcher's findings by using the Python file that he added as a supplement to his paper. It is the first time I am diving into Python, so the error might be extremely simple to fix, yet after two days I haven't still. For context, in the Readme file there's the following instruction:
"To run the script, make sure Python2 is installed. Put all files into one folder designated as “cf_dir”.
In the script I get an error at the following lines:
if __name__ == '__main__':
cf_dir, cf_file, cf_phys_file = sys.argv[1:4]
os.chdir(cf_dir)
cf = pd.read_csv(cf_file)
cf_phys = pd.read_csv(cf_phys_file)
ValueError: need more than 0 values to unpack
The "cf_file" and "cf_phys_file" are two major components of all files that are in the one folder named "cf_dir". The "cf_phys_file" relates only to two survey question's (Q22 and Q23), and the "cf_file" includes all other questions 1-21. Now it seems that the code is meant to retrieve those two files from the directory? Only for the "cf_phys_file" the columns 1:4 are needed. The current working directory is already set at the right location.
The path where I located "cf_dir" is as follows:
C:\Users\Marc-Marijn Ossel\Documents\RSM\Thesis\Data\Suitable for ML\Data en Artikelen\Per task Suitability for Machine Learning score readme\cf_dir
Alternative option in readme file,
In the readme file there's this option, but also here I cannot understand how to direct the path to the right location:
"Run the following command in an open terminal (substituting for file names
below): python cfProcessor_AEAPnP.py cf_dir cf_file cf_phys_file task_file jobTaskRatingFile
jobDataFile OESfile
This should generate the data and plots as necessary."
When I run that in "Command Prompt", I get the following error, and I am not sure how to set the working directory correctly.
- python: can't open file 'cfProcessor_AEAPnP.py': [Errno 2] No such file or directory
Thanks for the reading, and I hope there's someone who could help me!
Best regards & stay safe out there during Corona!!

cf_dir, cf_file, cf_phys_file = sys.argv[1:4]
means, the python file expects few arguments when called.
In order to run
python cfProcessor_AEAPnP.py cf_dir cf_file cf_phys_file task_file jobTaskRatingFile jobDataFile OESfile
the command prompt should be in that folder.
So, open command prompt and type
cd path_to_the_folder_where_ur_python_file_is_located
Now, you would have reached the path of the python file.
Also, make sure you give full path in double quotes for the arguments.
I am trying to make a python program that creates and writes in a txt file.
the program works, but I want it to cross the "hidden" thing in the txt file's properties, so that the txt can't be seen without using the python program I made. I have no clues how to do that, please understand I am a beginner in python.
I'm not 100% sure but I don't think you can do this in Python. I'd suggest finding a simple Visual Basic script and running it from your Python file.
Assuming you mean the file-properties, where you can set a file as "hidden". Like in Windows as seen in screenshot below:
Use operating-system's command-line from Python
For example in Windows command-line attrib +h Secret_File.txt to hide a file in CMD.
import subprocess
subprocess.run(["attrib", "+h", "Secret_File.txt"])

I'm following along with the examples in a translated version of Wes McKinney's "Python for Data Analysis" and I was blocked in first example of Chapter 2
I think my problem arose because I saved a data file in a wrong path. is that right?
I stored a file, usagov_bitly_data2012-03-16-1331923249.txt, in C:\Users\HRR
and also stored folder, pydata-book-mater, that can be downloaded from http://github.com/pydata-book in C:\Users\HRR\Anaconda2\Library\bin.
Depends.
You might change the location you save your File or eddit the path you give to your code in Line 10. Since you're yousing relativ Paths i guess your script runs in C:\Users\HRR\Anaconda2\Library\bin, which means you have to go back to C:\Users\HRR or use an absolute Path ... or move the File, but hell you don't want to move a file every time you want to open it, like moving word files into msoffice file to open it, so try to change the Path.
And allways try harder ;)
In python open() will open from the current directory down unless given a full path (in linux that starts with / and windows <C>://). In your case the command is open the folder ch02 in the directory the script is running from and then open usagov_bitly_data2012-03-16-1331923249.txt in that folder.
Since you are storing the text file in C:\Users\HRR\usagov_bitly_data2012-03-16-1331923249.txt and you did not specify the directory of the script. I recommend the following command instead open(C:\\Users\\HRR\\usagov_bitly_data2012-03-16-1331923249.txt)
Note: the double \ is to escape the characters and avoid tabs and newlines showing up in the path.
I'm writing a script to subtract one raster from another (Minus) and save the result in a geodatabase. The script works if I save the result to a normal folder:
arcpy.gp.Minus_sa("204nw06_c_r.tif","204nw06_be_r.tif","S:/Working_Folder/204nw06")
It fails when I try to save it to the gdb. It works in ArcCatalog and this is the Python snippet it gave me:
arcpy.gp.Minus_sa("214ne02_c_r.tif","214ne02_be_r.tif","S:/Working_Folder/LiDarTest.gdb/214ne02")
Can I save the result directly to the GDB? Or do I move the files to the GDB in a separate step?
You may try:
arcpy.gp.Minus_sa("214ne02_c_r.tif","214ne02_be_r.tif","S:/Working_Folder/LiDarTest.gdb/A214ne02")
In GDB, a raster name can't begin with number.
