Question

所以我想在python 3中看起来像这样：

How many hours are in your sample? 7
Enter the count of cars for hour #1: 2
Enter the count of cars for hour #2: 5
Enter the count of cars for hour #3: 9
Enter the count of cars for hour #4: 11
Enter the count of cars for hour #5: 12
Enter the count of cars for hour #6: 6
Enter the count of cars for hour #7: 5
Hour #1: # #
Hour #2: # # # # #
Hour #3: # # # # # # # # #
Hour #4: # # # # # # # # # # #
Hour #5: # # # # # # # # # # # #
Hour #6: # # # # # #
Hour #7: # # # # #
Average: # # # # # # #

到目前为止我写过这个：

def main():
    hourlist = number_cars()
    graphic = hourlist
    car_count_graphic_format(graphic)



def number_cars():
    hours = input("How many hours are in your sample? ")
    hours = int(hours)
    hourlist = []
    for i in range(hours):
        hourcount = input("Enter the count of cars for hour #" +str(i+1)+ ": ")
        hourcount = int(hourcount)
        hourlist.append(hourcount)
    hourlist.sort()
    return hourlist


def car_average(car_count):
    car_sum = 0
    for position in range(len(car_count)):
        car_sum = car_sum + car_count[position]
    average = car_sum / len(car_count)
    return average

def car_count_graphic_format(graphic):

    for x in range(graphic):
        graphic = "#" * graphic
        print("Hour #:" ,graphic,)





main()

但每当我运行它时，它都有一个错误，老实说我在这一点上陷入困境。如果有人可以帮助我，我会非常感激！感谢任何能够帮助我的人！

def car_count_graphic_format(graphic):
    for x in range(graphic):
        graphic = "#" * graphic
        print("Hour #:" ,graphic,)

在这里你应该小心，你经常重复使用名称graphic - 以解决不同的混淆问题。

该函数获取每小时的车辆计数列表，所以让我们调用该参数car_counts。我们想为每个条目打印一行，因此我们必须迭代car_counts中的元素。请注意，我们无法在此使用range(car_counts)，因为car_counts是一个列表但range()需要一个数字。相反，我们可以直接遍历列表以在每次迭代中获取其中的每个元素。由于我们还想记下小时，我们使用enumerate()来获取列表中元素的索引。由于小时从1开始，我们告诉enumerate()从1开始计算：

for hour, count in enumerate(car_counts, start=1):
    graphic = '# ' * count
    print('Hour #{}: {}'.format(hour, graphic))

最后，我们还想找出平均值，所以我们计算汽车总数，然后再除以小时数（列表长度）来得到平均车数：

def car_count_graphic_format(car_counts):
    total_cars = 0
    for hour, count in enumerate(car_counts, start=1):
        total_cars += count
        graphic = '# ' * count
        print('Hour #{}: {}'.format(hour, graphic))

    average = round(total_cars / len(car_counts))
    graphic = '# ' * average
    print('Average: {}'.format(graphic))

最后请注意，您不想要对hourlist功能中的number_cars进行排序，否则您将丢失车辆计数属于哪个小时的信息。

将数字列表翻译成图形格式（＃）
