weight = float(input("please enter your weight in kg: n" )) 
height = int(input(" please enter your height : n"))
age = input(" please enter your age :n")
activity_level = input(" please enter your activity level : ( lightly active  , moderately active , very active ) n" )
formula = 655.1 + (weight*9.563) + (height*1.850) - (age*4.676) 
lightly_active = formula*1.375
moderately_active = formula*1.55
very_active = formula*1.9
if activity_level == "lightly active" :
    print(lightly_active)
elif activity_level == "moderately active" :
    print(moderately_active)
