initial_credit = 200_000 # initial saving amount
years = 10 # years to save
interest = 0.03 # interest rate per year
credits = initial_credit
montly_investment = 10_000 # monthly saving


for y in range(years):
    for m in range(12):
        monthly_interest = (credits * (interest/12)) # calculate montly profit
        # adding monthly profit and monthly saving, with credits
        credits += (monthly_interest + montly_investment)
    # show new credit value, show monthly profit through only saving interest
    print(credits, ", ",monthly_interest)
