我有個(gè)問題。我對此有點(diǎn)困惑。我有來自其中的圖像和視頻的 URL。我想從該鏈接中獲取名稱并檢查它是圖像還是視頻并對其執(zhí)行操作。喜歡if filename.endwith(.jpg or .png): print("it's an image")else filename.endwith(.mp4, .avi): print("it's a video) 文件名是一個(gè)列表。所有數(shù)據(jù)都存儲在其中： ls = ["C:/Users/OB/Desktop/DevoMech Project/6.JPG" , "C:/Users/OB/Desktop/DevoMech Project/7.JPG"] if ls.endwith(.JPG or .JPEG): item1 = QtWidgets.QListWidgetItem(QIcon(ls), "item1") self.dlistWidget.addItem(item1) #item2 = QtWidgets.QListWidgetItem(QIcon("C:/Users/OB/Desktop/DevoMech Project/7.JPEG"), "item2") self.dlistWidget.addItem(item2)而不是第一項(xiàng)，而是顯示實(shí)際名稱。

如果可能的話，我總是更喜歡使用 os 內(nèi)置的路徑并捕獲不受支持的類型
import os
video_types = ('.mp4', '.avi', '.jpeg')
image_types = ('.png', '.jpg')
filenames = ["/test/1.jpg","/test/2.avi","/test/unknown.xml","/test/noextention"]
for filename in filenames:
print(filename)
if os.path.splitext(filename)[1] in video_types:
print("Its a Video")
elif os.path.splitext(filename)[1] in image_types:
print("Its an Image")
else:
print("No Idea")
/test/1.jpg
Its an Image
/test/2.avi
Its a Video
/test/unknown.xml
No Idea
/test/noextention
No Idea

from urlparse import urlparse
from os.path import splitext
url = "sample/test/image.png"
image_formats = [".png", ".jpeg"]
video_formats = [".mp4", ".mp3", ".avi"]
def get_ext(url):
"""Return the filename extension from url, or ''."""
parsed = urlparse(url)
root, ext = splitext(parsed.path)
return ext
if get_ext(url) in image_formats:
print("it's an image")
elif get_ext(url) in video_formats:
print("it's a video")
else:
print("some differnet format")
