Build a very simple front-end to upload 5 csv files and execute an existing python script for these csv files

I have an existing and working python script that takes 5 csv files which are uploaded into a directory (using ftp), performs certain functions on them and then produces 4 csv files in a directory. What I need: I need you to build a very simple front-end (for my own use) to upload the 5 csv input files and execute the existing python script for these csv files, and then present a download link/s for the output files. Basically, the purpose of the script is to avoid having to use ftp to upload and download the input and output files and to avoid having to manually execute the python script via ssh. The operating environment: Distribution: CentOS Linux release 7.9.2009 (Core) Operating System: Linux 3.10.0-1160.76.1.el7.x86_64 (SMP) CPU: [24x] 1288.57Mhz Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz (15360 KB Cache) System Memory: 32138.23 MB The size of the files: 5 - 10 MB combined (in total). Execution time of python script: about 30-60 secs. In your bid, mention what programming language you intend to use. Thank you
