Question

这段代码有什么问题？我试图运行它，但一直给我错误，我无法弄明白。

def main():
    # Variables
    total_sales = 0.0

    # Initialize lists
    daily_sales = [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
    days_of_week = ['Sunday', 'Monday', 'Tuesday',
                    'Wednesday', 'Thursday' 'Friday',
                    'Saturday']

    for i in range(7):
        daily_sales[i] = float(input('Enter the sales for ' \
                                     + days_of_week[i] + ': '))

    for number in daily_sales:
        total_sales += number

    # Display total sales
    print ('Total sales for the week: $', \
           format(total_sales, ',.2f'), sep='')

# Call the main function.
main()

Answer 1

days_of_week = ['Sunday', 'Monday', 'Tuesday',
                'Wednesday', 'Thursday', 'Friday',
                'Saturday']

你忘记了星期四之后的,，这就是它超出范围的原因。

您的代码：

def main():
    # Variables
    total_sales = 0.0

    # Initialize lists
    daily_sales = [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
    days_of_week = ['Sunday', 'Monday', 'Tuesday',
                    'Wednesday', 'Thursday', 'Friday',
                    'Saturday']

    for i in range(7):
        daily_sales[i] = float(input('Enter the sales for ' \
                                 + days_of_week[i] + ': '))

    for number in daily_sales:
        total_sales += number

    # Display total sales
    print('Total sales for the week: ${:.2f}'.format(total_sales))

# Call the main function.
main()

也许我们可以稍微改进一下这个代码：

def main():
    # Initialize lists
    daily_sales = [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
    days_of_week = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday',
                    'Friday', 'Saturday']

    # Use `enumerate` to get the item directly.
    for index, day in enumerate(days_of_week):
        daily_sales[index] = float(
            input('Enter the sales for {0}: '.format(day)))

    # Use the built-in `sum` to sum the sales.
    total_sales = sum(daily_sales)

    # Display total sales
    print('Total sales for the week: ${:.2f}'.format(total_sales))


# Call the main function.
main()

我把它扔进编辑器时发现了一些缩进错误。修复后，在{lord63 ,之后添加'Thursday'。 j发现，您需要清理并修复print中的最终main()声明。请尝试下面的代码，因为它现在对我很有用：

def main():
 # Variables
    total_sales = 0.0

 # Initialize lists
    daily_sales = [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
    days_of_week = ['Sunday', 'Monday', 'Tuesday',
                'Wednesday', 'Thursday', 'Friday',
                'Saturday']

    for i in range(7):
        daily_sales[i] = float(input('Enter the sales for '+ \
                                      days_of_week[i] + ': '))

    for number in daily_sales:
        total_sales += number

    # Display total sales
    print ('Total sales for the week: $' \
           + format(total_sales, '.2f'))

# Call the main function.
main()

这段代码有什么问题？我弄清楚了
