I need help with adding the weighted points at the end of every subject please

in python

def validate$\_$input$($message$,$ offset$)$:

if shifted $>$ ord$(\text{'}$Z$\text{'})$:

shifted $-=26$ # Wrap around if it goes past $\text{'}$Z$\text{'}$

encrypted$\_$message.append$($chr$($shifted$))$

else:

encrypted$\_$message.append$($char$)$

return $\text{'}\text{'}.$join$($encrypted$\_$message$)$
