如何在Prettytable中删除值小于0％的行

如何解决如何在Prettytable中删除值小于0％的行

我正在尝试获取否。由于循环遍历每个单个像素而放置的图像中的颜色数目显示的是几种颜色，其值小于0％。我正在尝试删除在prettytable中显示的以下列表中百分比值小于0％的行

代码如下：

img = Image.open("bnw.jpg")
size = w,h = img.size
data = img.load()

colors = []
for x in range(w):
    for y in range(h):
        color = data[x,y]
        hex_color = '#'+''.join([hex(c)[2:].rjust(2,'0') for c in color])
        colors.append(hex_color)

pt = prettytable.prettytable(['Color','Count','Percentage'])

total = w * h

for color,count in Counter(colors).items():
    percent = int(count/total * 100)
    pt.add_row([color,count,percent])


# res = []
# for i in colors:
#     if i not in res:
#         res.append(i)
# print("The list after removing duplicates : " + str(res))

print(pt,total)

这是输出

+---------+--------+------------+

| #fdfdfd |  932   |     0      |

| #f4f4f4 |   5    |     0      |
+---------+--------+------------+ 666000

这是我要达到的必需输出

+---------+--------+------------+
|  Color  | Count  | Percentage |
+---------+--------+------------+
| #ffffff | 478329 |     71     |
| #000000 | 179583 |     26     |
+---------+--------+------------+ 666000

解决方法

您怎么样呢？只是不首先添加它们？另外，您正在寻找等于或小于零的值。

for color,count in Counter(colors).items():
    percent = int(count/total * 100)
    if percent > 0:
        pt.add_row([color,count,percent])
