Python封装：实现输出一个文件夹下所有各个文件的地址存为列表集合内——Jason niu

def getAllImages(folder):
    assert os.path.exists(folder)
    assert os.path.isdir(folder)
    imageList = os.listdir(folder)
    imageList = [os.path.abspath(item) for item in imageList if os.path.isfile(os.path.join(folder, item))]
    print(imageList[1])
    return imageList
print (getAllImages(r"F:\\File_Python\\Python_example\\faceRecognition-master\\Original_picture\\Jason_niu"))
