那里。我想使用 openpyxl 更改图片的大小。宽度 = 11.21 厘米。高度 = 7.69 厘米。

或者我想更改与单元格相同的图片大小。

我的代码如下。它可以制作非常小的图片。你可以帮帮我吗？

from openpyxl import load_workbook
from openpyxl.drawing.image import Image

filename="1.xlsx"
wb = load_workbook(filename)
ws = wb.worksheets[0]
img = Image('13.5.jpg')
img.width = 11.21
img.height = 7.69
ws.add_image(img, 'B13')
wb.save('1.xlsx')
print("done")

我想在 django 上的列表视图中使用重定向。

如果用户名是yusl，他连接到www.photo.com/user/yusl，他可以看到他的照片列表。如果他连接到 www.photo.com/user/dksdl，他就会重定向 www.photo.com/user/yusl。

但有错误。错误是

这是我的 views.py

class PhotoListView(ListView):
    model = Photo

    def get_context_data(self, …

这是文本：\xec\x97\x90\xec\xbd\x94\xed\x94\x84\xeb\xa1\x9c\xeb\xb9\x84\xec\x97\xa0 (247540/\xeb\xa7\xa4\ xec\x88\x98)\xeb\x8c\x80\xec\x9e\xa5\xeb\x8b\x98\xeb\xa8\xbc\xec\xa0\x80 24\xeb\x85\x84\xec\x9c\xbc\ xeb\xa1\x9c\xea\xb0\x80\xea\xb2\xa0\xec\x8a\xb5\xeb\x8b\x88\xeb\x8b\xa4

我只想得到 247540

result = re.search(r"\\(([0-9]+)\\)", link.text)\nprint(result, link.text)\n

它返回无。

这是完整的代码
