Question

我目前正在研究营养计划器，该程序将允许用户每个日历日计划膳食。作为一个演示，我从JSON文件中加载了数据，包括餐食名称和卡路里，允许用户选择他们想要的餐食，等等。我希望他们每天都能做到并组织其中日历。

这是我为膳食计划者编写的代码，该代码可以按我希望的方式工作：

breakfastInput = input("What would you like for breakfast? ")
breakfastChoice = [breakfastChoice for breakfastChoice in breakfast if breakfastInput in breakfastChoice][0]
breakfastName = breakfastChoice[0]
breakfastCalories = breakfastChoice[1]
calories = calories - breakfastCalories
print("You have {} calories remaining.".format(calories))

lunchInput = input("What would you like for lunch? ")
lunchChoice = [lunchChoice for lunchChoice in lunch if lunchInput in lunchChoice][0]
lunchName = lunchChoice[0]
lunchCalories = lunchChoice[1]
calories = calories - lunchCalories
print("You have {} calories remaining.".format(calories))

dinnerInput = input("What would you like for dinner? ")
dinnerChoice = [dinnerChoice for dinnerChoice in dinner if dinnerInput in dinnerChoice][0]
dinnerName = dinnerChoice[0]
dinnerCalories = dinnerChoice[1]
calories = calories - dinnerCalories
print("You have {} calories remaining.".format(calories))

if input("Would you like any snacks? ") == "yes":
    print(snacks)
    snacksInput = input("What snack would you like? ")
    snacksChoice = [snacksChoice for snacksChoice in snacks if snacksInput in snacksChoice][0]
    snacksName = snacksChoice[0]
    snacksCalories = snacksChoice[1]
    calories = calories - snacksCalories
    print("You have {} calories remaining.".format(calories))
else:
    print("Your day has been planned with a remaining {} calories.".format(calories))

如何允许用户选择日期，然后执行此功能？

例如，可以将lunchName和dinnerName分配给每一天。

Answer 1

您可以使用python's datetime library。举个简单的例子：

from datetime.datetime import strptime
lunchDateInput = input("What date are you having lunch on?")
lunchDate = strptime(lunchDateInput, "MM/DD/YYYY")

您对该项目的功能抱有很大的野心，但是如果您使用datetime库并阅读文档，那么您也可以弄清楚调度位。

每个日历日期执行功能
