How do I create a submission file?

I’m new to the competition and I want to know how do I create a submission file.
Should I upload my model as well?

Thanks.

Hello and welcome to AIcrowd.

You can see the sample submission file and submit a csv like that.

There is no need to submit your model.

Thanks for quick response. I want to know how do I create submission files like that.
If there is a sample code available, that would be great. Thanks for your help.
