Help with parameter variables losing value - kofipython - Feb-24-2018 Hello All, I need help. Can someone tell me why I am not getting any results. Look like I am losing the variables values. Here is my code. # Global constant for Calories CALORIES_FROM_FAT = 9 CALORIES_FROM_CARBS = 4 # main module # Get grams fat def main(): gramsFat = gramsCarbs = caloriesFat = caloriesCarbs = 0.0 getFat(gramsFat) setFat(gramsFat,CALORIES_FROM_FAT) getCarbs(gramsCarbs) setCarbs(gramsCarbs, CALORIES_FROM_CARBS) showCarbs(gramsFat, gramsCarbs, caloriesFat, caloriesCarbs) # The getFat module gets weight and stores it # in the inputFat reference variable. def getFat(gramsFat): gramsFat = float(input('Enter the number of fat grams consumed: ')) def setFat(gramsFat,CALORIES_FROM_FAT): caloriesFat = float(gramsFat * CALORIES_FROM_FAT) def getCarbs(gramsCarbs): gramsCarbs = float(input("Enter carbohydrate grams consumed: ")) def setCarbs(gramsCarbs, CALORIES_FROM_CARBS): caloriesCarbs = gramsCarbs * CALORIES_FROM_CARBS # ------------------------------------------------------------------------ # The showCarbs function accepts the number of grams of fat and of carbs, # as well as the calories from fat and from carbs, as arguments # and displays the resulting calories def showCarbs(gramsFat, gramsCarbs, caloriesFat, caloriesCarbs): print("Grams of Fat: ", gramsFat) print("Result calories: ", caloriesFat) print("Grams of Carbs: ", gramsCarbs) print("Result calories: ", caloriesCarbs) # Call Main Function main() RE: Help with parameter variables losing value - largecat - Feb-24-2018 # Global constant for Calories CALORIES_FROM_FAT = 9 CALORIES_FROM_CARBS = 4 # main module # Get grams fat def main(): gramsFat=getFat() caloriesFat=setFat(gramsFat,CALORIES_FROM_FAT) gramsCarbs=getCarbs() caloriesCarbs=setCarbs(gramsCarbs, CALORIES_FROM_CARBS) showCarbs(gramsFat, gramsCarbs, caloriesFat, caloriesCarbs) # The getFat module gets weight and stores it # in the inputFat reference variable. def getFat(): gramsFat = float(input('Enter the number of fat grams consumed: ')) return gramsFat def setFat(gramsFat,CALORIES_FROM_FAT): caloriesFat = float(gramsFat * CALORIES_FROM_FAT) return caloriesFat def getCarbs(): gramsCarbs = float(input("Enter carbohydrate grams consumed: ")) return gramsCarbs def setCarbs(gramsCarbs, CALORIES_FROM_CARBS): caloriesCarbs = gramsCarbs * CALORIES_FROM_CARBS return caloriesCarbs # ------------------------------------------------------------------------ # The showCarbs function accepts the number of grams of fat and of carbs, # as well as the calories from fat and from carbs, as arguments # and displays the resulting calories def showCarbs(gramsFat, gramsCarbs, caloriesFat, caloriesCarbs): print("Grams of Fat: ", gramsFat) print("Result calories: ", caloriesFat) print("Grams of Carbs: ", gramsCarbs) print("Result calories: ", caloriesCarbs) # Call Main Function main() each function should have a return at the end, RE: Help with parameter variables losing value - Larz60+ - Feb-24-2018 I run and get results: Enter the number of fat grams consumed: 5 Enter carbohydrate grams consumed: 5 Grams of Fat: 5.0 Result calories: 45.0 Grams of Carbs: 5.0 Result calories: 20.0 Process finished with exit code 0 RE: Help with parameter variables losing value - buran - Feb-24-2018 (Feb-24-2018, 08:01 AM)Larz60+ Wrote: I run and get resultsYou probably run largecat's code, not the one from OP. RE: Help with parameter variables losing value - Larz60+ - Feb-24-2018 Yes, you're correct! |
