Question

所以我是一个非常年轻的程序员，我使用python，并且我正在尝试在python中创建一个跟踪我的家务的应用程序，当你完成登录时，就像当你以我的身份登录时，当你完成时，它退出它，我希望我的父母能够看到那些东西，这就是为什么有登录，我希望它是变量空的地方，而你的父母登录，它说没有任何东西变量，并要求你把一些东西放在变量中，我也希望当我的个人资料结束时，它再次要求登录，这里是代码。（为了隐私，我已经从代码中取出了我的名字。）

print ("Welcome to Chore Tracker, ")

name = raw_input("Who is this?")

if name == "******": 
    c1 = raw_input("Have you kept your room clean?")
    c2 = raw_input("Did you fed IVAN?")
    c3 = raw_input("Have you fed your hamster?")
    c4 = raw_input("How many bags of trash have you taken out?")
    print "If you did all of those things, you have 6 dollars, plus " +     c4 + ", dollars!"
    print "If you did two of those things, you have 4 dollars, plus " + c4 + ", dollars!"
    print "If you did only one thing, you have two dollars, plus " + c4 + ", dollars!"

elif name == "Mom":
    print("Hello, Mom!, if an error pops up, that means I didn't put anything down yet!")
    print "Room clean, " + c1
    print "IVAN fed, " + c2
    print "Hamster fed, " + c3
    print "And I took out, " + c4 + ", bags of trash!"
    print "So I have 2, 4, or 6 dollars, plus, " + c4 + ", dollars!"

else:
    print("Hello, Dad!, if an error pops up, that means I didn't put anything down yet!")
    print "Room clean, " + c1
    print "IVAN fed, " + c2
    print "Hamster fed, " + c3
    print "And I took out, " + c4 + ", bags of trash!"
    print "So I have 2, 4, or 6 dollars, plus, " + c4 + ", dollars!"

Answer 1

if-elif-else通常被称为“分支”语句，因为在每种情况下，您都选择是否采用该分支执行。因此，如果name == "******"，您只会执行第一个块而不是elif或else。但是，您只在第一个分支中声明c1，c2，c3和c4，但在所有分支中使用它。因此，您需要将变量声明移到外部您的if-elif-else阻止，以便始终在if-elif-else阻止之前执行。

实施例

print ("Welcome to Chore Tracker, ")

name = raw_input("Who is this?")
c1 = raw_input("Have you kept your room clean?")
c2 = raw_input("Did you fed IVAN?")
c3 = raw_input("Have you fed your hamster?")
c4 = raw_input("How many bags of trash have you taken out?")

if name == "******": 
    print "If you did all of those things, you have 6 dollars, plus " +     c4 + ", dollars!"
    print "If you did two of those things, you have 4 dollars, plus " + c4 + ", dollars!"
    print "If you did only one thing, you have two dollars, plus " + c4 + ", dollars!"

elif name == "Mom":
    print("Hello, Mom!, if an error pops up, that means I didn't put anything down yet!")
    print "Room clean, " + c1
    print "IVAN fed, " + c2
    print "Hamster fed, " + c3
    print "And I took out, " + c4 + ", bags of trash!"
    print "So I have 2, 4, or 6 dollars, plus, " + c4 + ", dollars!"

else:
    print("Hello, Dad!, if an error pops up, that means I didn't put anything down yet!")
    print "Room clean, " + c1
    print "IVAN fed, " + c2
    print "Hamster fed, " + c3
    print "And I took out, " + c4 + ", bags of trash!"
    print "So I have 2, 4, or 6 dollars, plus, " + c4 + ", dollars!"

Answer 2

目前最大的问题似乎是

您的变量在其中一个if分支中声明，因此无法从其他分支中访问
一旦你退出，（所以，你妈妈可以登录），你的变量就不会再填充了。

假设你保持程序运行，（这样2不是问题），这就是我的建议：

c1 = "No"
c2 = "No"
c3 = "No"
c4 = "0"

def run():
    print ("Welcome to Chore Tracker, ")
    name = raw_input("Who is this?")

    if name == "******": 
        c1 = raw_input("Have you kept your room clean?")
        c2 = raw_input("Did you fed IVAN?")
        c3 = raw_input("Have you fed your hamster?")
        c4 = raw_input("How many bags of trash have you taken out?")
        print "If you did all of those things, you have 6 dollars, plus " +     c4 + ", dollars!"
        print "If you did two of those things, you have 4 dollars, plus " + c4 + ", dollars!"
        print "If you did only one thing, you have two dollars, plus " + c4 + ", dollars!"

    elif name == "Mom":
        print("Hello, Mom!, if an error pops up, that means I didn't put anything down yet!")
        print "Room clean, " + c1
        print "IVAN fed, " + c2
        print "Hamster fed, " + c3
        print "And I took out, " + c4 + ", bags of trash!"
        print "So I have 2, 4, or 6 dollars, plus, " + c4 + ", dollars!"

    else:
        print("Hello, Dad!, if an error pops up, that means I didn't put anything down yet!")
        print "Room clean, " + c1
        print "IVAN fed, " + c2
        print "Hamster fed, " + c3
        print "And I took out, " + c4 + ", bags of trash!"
        print "So I have 2, 4, or 6 dollars, plus, " + c4 + ", dollars!"


while True:
    run()

初始化初始化意味着您的程序不会抛出错误，并在您登录前显示当前状态。

无限while循环将确保您的程序在用户完成后再次请求登录。
