平均降雨量計算器

Question

這是更新的程序我至今寫：

# This program averages rainfall per month. It asks the user for the number 
# of years. It will then display the number of months, the total inches of 
# rainfaill, and the average rainfall per month for the entire period. 

# Get the number of years. 

total_years = int(input('Enter the amount of years: ')) 

# Get the amount of rainfall for each month of each year. 

for years in range(total_years): 
    # Initialize the accumulator. 
    total = 0.0 
    print('Year', years + 1) 
    print('----------------') 
    for month in ('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'): 
     inches = float(input(month)) 
     total += inches 

total_inches = total 

total_month = total_years * 12 

average_inches = total/total_month 



     # Display the average. 
print('The total number of months is: ', total_month) 
print('The total inches of rainfall is: ', total_inches) 
print('The average rainfall per month for the entire period is: ', average_inches) 

print() 

這是試圖測試代碼時，我得到了新的錯誤消息：在

Traceback (most recent call last): File 
"C:/Users/Alex/Desktop/Programming Concepts/Homework 2/Chapter 
5/Average Rainfall maybe.py", line 23, in <module> 
average_inches = total/month 
TypeError: unspupported operand type(s) for /: 'float' and 'str' 

任何想法如何修復/改進此代碼？

現在，我需要解決的是我的計算。我認爲他們錯了（23-27行）。

Answer 1

發生錯誤的錯誤消息的引用：

average_inches = total/month 

具體地說，

TypeError: unspupported operand type(s) for /: 'float' and 'str' 

..是說，它不能除以一個字符串（month）的浮子（total）。

month要由分（它只是包含「一」或任何字符串）..你想要的number of months

以提示劃分完全錯誤的事情，我做建議開始：

ALL_MONTHS = ('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'): 

然後你的循環更改爲：

for month in ALL_MONTHS: 

這樣，您可以稍後查閱ALL_MONTHS再次...
