python - 使用列表似乎无法将工作日与数字相匹配

问题描述

我正在尝试使用列表将星期几与数字匹配，但我不确定如何。例如，我想让它知道第 1 天是星期一，第 2 天是星期二，第 3 天是星期三，第 4 天是星期四，第 5 天是星期五

我已经用列表尝试了多种方法，但我似乎无法弄清楚

这就是我试图让它看起来像：

Enter sales for day 1: 10.22 (User input)
Enter sales for day 2: 4.12 (User input)
Enter sales for day 3: 3.78 (User input)
Enter sales for day 4: 6.82 (User input)
Enter sales for day 5: 22.45 (User input)

Maximum sales was on Friday which is $22.45
Minimum sales was on Wednesday which is $3.78
Total weekly sales were $47.39
Average of the sales is $9.48
Sales too low for commission must earn more than $100

这是我到目前为止所拥有的：

print ("Sales Calculator Program")

print ('\n')


expenses = []
for day_number in range (1, 5 + 1):
    while True:
        user_input = float(input(f"Enter sales for day {day_number}\n> "))
        if user_input >= 0:
            expenses.append(user_input)
            break
        else:
            print(f"Amount may not be negative. Try again:")
days = ('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday')




print ('\n')       

finalExpenses = sum(expenses)
average = finalExpenses / 5
maxExpenses = max(expenses)
minExpenses = min(expenses)

if finalExpenses < 100:
    print( "Sales too low for commission must earn more than 100$")
elif finalExpenses < 250:
    print ( "You get a commission of 25$")
elif finalExpenses < 500:
    print ( "You get a commission of 30$")
else:
    print ( "You get a commission of 40$")




print ("Maximum sales on is $" +str(maxExpenses))
print ("Minimum sales is $" +str(minExpenses))
print ("Total weekly sales were $" +str(finalExpenses))
print ("Average of the sales is $" +str(average))

除了将日期与数字匹配并按照示例所示打印之外，我已经完成了所有工作。

谢谢

解决方案

为确保我正确理解问题 - 您有两个列表：

  • [10.22, 4.12, 3.78, 6.82, 22.45]
  • ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']

并且您希望将第一个列表中的数字与第二个列表中的天数相匹配。

你想要的是list.index()方法：

maxExpenses = max(expenses)
index = expenses.index(maxExpenses)
day = days[index]

然后你print()可以：

print ("Maximum sales on ' + day + ' is $" +str(maxExpenses))
