在这个 Python 问题上遇到一些麻烦

Question

I'm tasked with this question:

Design a program that asks the user to enter a store's sales for each day of the week. The amounts should be stored in a list. Use a loop to calculate the total sales for the week and display the result.

I've written this thus far

listf=[0,]
def total_list(listf):
sales_total= int(input("enter weekly sales:"))

for x in range(len(listf)):
    sales_total +=listf[x]
return sales_total

Answer 1

You're asking the user for the entire week's sales:

sales_total= int(input("enter weekly sales:"))

but the spec says that you should be asking them for the sales for each day of the week (individually) and put them in a list:

asks the user to enter a store's sales for each day of the week. The amounts should be stored in a list.

That might look something like:

>>> sales = [int(input(f"Enter the sales for {day}: ")) for day in "SMTWTFS"]
Enter the sales for S: 0
Enter the sales for M: 4
Enter the sales for T: 5
Enter the sales for W: 3
Enter the sales for T: 5
Enter the sales for F: 9
Enter the sales for S: 1

Now you have all the daily sales in a list:

>>> sales
[0, 4, 5, 3, 5, 9, 1]

and you can sum them to get the weekly sales:

>>> sum(sales)
