Build and deploy a web app on AWS

I have a python code which does the following:
- Takes an input file
- Does pandas processing and calls bunch of AWS services
- Generates an output file.

I need a web app which on the basis of the above python code:
1. Takes an input file (the UI should give two options here, s3 path and local file upload)

2. The python asks for some python `input()`s. The UI should have the output of the script get displayed on the UI nicely and ask the value for these inputs on the fly.
OR
2. You may take all the `input()`s in the beginning and then run the script. And just output the script.

3. Generates an output file. Save it to S3 and also give the option.

This needs to be deployed on AWS. Should have a public endpoint but be only accessible via authentication.
