Showing and saving the output of a python file run through bash - Rim - Oct-04-2021

Hi all,

I'm new to the world of Python, linux and programming in general so my question may be very basic but I can't find an answer anywhere.

I'm running a python file (to do a regression so I'm expecting tables as result) on a virtual cluster using a shell file. The job launches and runs fine but I can't visualize the result (print them on prompt) nor create a file with the output.

What could I do to see the results of my python file? Is there a command to put in the bash or in my Python code?

I've already tried a couple of solutions that did not work like putting the following command in the bash python

mycode.py > SomeFile.txt

This generated an empty txt file named SomeFile.

I also tried adding the following lines in my Python code to get the results in tex and pickle files but it didn't work either:

print(f"Output file: {results.data.htmlFileName}")
results.writeLaTeX()
print(f'LaTeX file: {results.data.latexFileName}')
results.writePickle()
print(f'Pickle file: {results.data.pickleFileName}')

Thank you in advance for any help Smile

PS: To have a better idea of the Python code that I want to run on the cluster I attached the script mycode.py (small clarification: since it is the first code I run so as a test I only ask for 5 Monte Carlo draws but the objective is to ask for 100000 draws or more)

You should tell Python to run the file, so from bash one can do:

python my_program.py > my_program_output.txt

From within Python one can print to file and write to file.

Thank you perfringo!

That is exactly what I did. I just forgot to put it in my question here.

The resulting txt file is empty :/

why not test it with a simple example. Create a script "hello.py" with one print statement like print("Hello World").
On bash (the line starts with a $) go to the directory of your script and type (the interpreters name is python or python3):
python3 hello.py
You should either see "Hello World" or some kind of error.
