导入另一个文件

Question

我这里有一些代码，这有点草率，有什么办法可以将图像，编码和名称放入单独的文件中，并将它们导入到主代码中使用？我尝试将它们放入一个单独的文件中，然后导入它们，但是它仍然显示未定义的错误？谁能帮助我找出原因或如何解决。

主要代码

# PLEASE NOTE: This example requires OpenCV (the `cv2` library) to be installed only to read from your webcam.
# OpenCV is *not* required to use the face_recognition library. It's only required if you want to run this
# specific demo. If you have trouble installing it, try any of the other demos that don't require it instead.

# Get a reference to webcam #0 (the default one)
video_capture = cv2.VideoCapture(0)

    # Hit 'q' on the keyboard to quit!
    if cv2.waitKey(1) & 0xFF == ord('q'):

我希望分离的代码

me_image = face_recognition.load_image_file("me.jpg")
me_face_encoding = face_recognition.face_encodings(me_image)[0]

mom_image = face_recognition.load_image_file("mom.jpg")
mom_face_encoding = face_recognition.face_encodings(mom_image)[0]

mattm_image = face_recognition.load_image_file("mattm.jpg")
mattm_face_encoding = face_recognition.face_encodings(mattm_image)[0]

soph_image = face_recognition.load_image_file("soph.jpg")
soph_face_encoding = face_recognition.face_encodings(soph_image)[0]

known_face_encodings = [
    me_face_encoding,
    mom_face_encoding,
    mattm_face_encoding,
    soph_face_encoding
]
known_face_names = [
    "Jacob North",
    "Shelly North",
    "Matt Mersino",
    "Sophia North"
]

我只想使其更整洁，更容易使用。
