如何修改DegreeDays函数，使其输出elif与if分支求和的二元数组

Let's sort this out — your current function is collecting individual difference values, but what you need is to calculate the total sum for each condition, then return those sums in the order of the elif branch first, then the if branch.

Here's how to adjust the code:

def DegreeDays(val1):
    # Initialize sums for each condition
    heating_total = 0  # For 52 < val < 61: sum of (60 - val)
    cooling_total = 0  # For 79 < val < 97: sum of (96 - val)
    
    for val in val1:
        if 79 < val < 97:
            cooling_total += 96 - val
        elif 52 < val < 61:
            heating_total += 60 - val
    
    # Return totals in the requested order: heating first, then cooling
    return [heating_total, cooling_total]

Let's test this with your input: #

When you call DegreeDays([67, 78, 96, 80, 75, 62, 53]):

• Only 53 falls into the elif range: 60 - 53 = 7 → heating_total is 7
• 96 and 80 fall into the if range: (96-96) + (96-80) = 0 +16 =16 → cooling_total is16
• The function returns [7, 16], which matches exactly what you need.

The key changes here are:

• Replacing the results list with two sum variables to accumulate totals instead of individual values
• Calculating the sum for each condition as we iterate through the input list
• Returning the sums in the specific order you requested (elif branch total first, then if branch total)
