How to create forecast lead time with python?

[Dioumacor FAYE]

Hello,
I wanted to create on different days the deadline forecast files (2, 3, 4,
and 5 deadlines). The file is in NetCDF format. The objective is to see
later on these different forecast deadlines which one gives the best score.
If anyone can help me to do?
