Shell script looping

Dear Expert guru

I need your help. I have a command which I am running in terminal colsole.
I want to make it run for all the files in the folder one by one and save the output as txt file. At the moment, I can only run it one by one manually for single file and get the output in colsole.

Original command is

python main.py -m test -class input.csv 

and
I am trying looping like this in shell script loop

for file in  *.csv; 
do
    python main.py -m test -class  <"$file" &
done

can you help me in making a proper loop?

Greetings

What I have tried:

I am trying to make a shell script .sh file for the looping command for all available files which get run one by one and save the output which is text in console.
Yet I am only able to run this command in colsole terminal manually each time.
