when running code in python outside of a function the following works.

however the question is how can i get it to work inside a function eg: when adding say: def house_hunting(annual_salary, portion_saved, total_cost):

annual_salary= float(input("Enter your annual salary: ")) portion_saved= float(input("Enter the percent of your salary to save, as a decimal: ")) total_cost= float(input("Enter the cost of your dream home: ")) r = 0.04 ms = annual_salary/12 current_saving = 0 months = 0 portion_down_payment = 0.25 down_payment= total_cost*portion_down_payment while current_saving < down_payment: current_saving = current_saving + (ms*portion_saved) + (current_saving*r/12) months += 1 print("Number of Months required for down payment:", months)
