I am completely new to this QGIS. I have been given a task to automate node demand (amount of water needed). I have a "XYZ" district data set which include:

  • district shp files,
  • village road shp files,
  • Highway Road shp files,
  • elevationpoints shp files.
  • I have a populations file of that district too.


node demand=(population region of area) * (Average liter of water consumed by a person in a day ).

I need to write a python code so that it can automated and save man power and time.

How should I start step by step in QGIS to achieve this goal?
