题目1

注册课程小游戏程序
研究下面的例子，并编写一个与这些例子完全相同的程序。使用for loop和break来解决问题。提示用户输入课程数量，是否选择，并且课程代码，最后还需显示已经完成的课程注册数量或者未完成的注册数量，如下如所示：

代码

num_subjects = int(input("How many subjects would you choose for this session: "))
enrolled_subjects = 0

while enrolled_subjects < num_subjects:
    continue_enrollment = input("Would you like to continue subject enrolment? (Y/N): ")

    if continue_enrollment.upper() == "Y":
        subject = input("Which subject would you like: ")
        print("You have successfully enrolled in", subject + ".")
        enrolled_subjects += 1
    else:
        break

remaining_subjects = num_subjects - enrolled_subjects

if remaining_subjects == 0:
    print("You have finished the enrollment of all", num_subjects, "subjects.")
else:
    if remaining_subjects == 1 :
        print("You have not completely finished the enrollment. There is", remaining_subjects, "subject to be enrolled.")
    else:
        print("You have not completely finished the enrollment. There are", remaining_subjects, "subjects to be enrolled.")

题目2

记账小程序
研究下面的例子，并编写一个与这些例子完全相同的程序。货币在小数点后显示两位数字。提示用户输入一些基本信息，，并完成折扣与优惠卷的使用，如下图所示：


这题需要注意的是输出格式，简单的计算，提示：使用if-else语句

代码

CF = float(input("Enter the cost of Fruit&Veg: "))
CD = float(input("Enter the cost of Deli&Chilled Meals: "))
CP = float(input("Enter the cost of Pantry: "))

Reword = input("Would you like to use your $10 Everyday Rewards Dollars? Y or N: ")

CFC = str(CF)
CDC = str(CD)
CPC = str(CP)

if disc.upper() == 'Y' and Reword.upper() == 'Y':
    Total = CF + CD + CP
    CT = str(Total)

    w_discount = (CF + CD + CP) * 0.1
    total_cost = Total - w_discount
    s = total_cost - 10
    print("\nReceipt:")
    print("Fruit&Veg {:>45.2f}".format(CF))
    print("Deli&Chilled Meals {:>36.2f}".format(CD))
    print("Pantry {:>48.2f}".format(CP))
    print("Total {:>49s}".format("${:.2f}".format(Total)))

    print("\n${:.2f} saved with your Woolworths Mobile discount".format(w_discount))
    print("Promotional Price {:>37s}".format("${:.2f}".format(total_cost)))

    print("\n$10 Everyday Rewards Dollars enjoyed")
    print("\nPayment {:>47s}".format("${:.2f}".format(s)))

elif disc.upper() == 'Y' and Reword.upper() == 'N':
    Total = CF + CD + CP
    CT = str(Total)
    s = Total * 0.1
    w_discount = Total * 0.1

    print("Total {:>49s}".format("${:.2f}".format(Total)))

    Total = CF + CD + CP
    CT = str(Total)
    s = Total - 10
