How to get shadow price/dual in gurobi attached to the constraints it is referring to

I am new to python and currently using gurobi to solve some optimization problems. I know that i can use model.getAttr('Pi', m.getConstrs()) function to get the shadow(dual) prices. This function however just spits out an array of values. I have about 30 constraints and it is hard to track which value is attached to which constraint. Is there a way you can print out the shadow price where it specifies which shadow price is attached to which constraint?

Thank you very much.

One option is to loop over your constraints and print the respective name and dual variable:

for c in m.getConstrs():
    print(f"{c.VarName}: {c.Pi}")
