对指定目录下的图片，取图片名（不包含图片的扩展名）、将文件路径和图片名分开、将文件名和图片扩展名分开

import os
# 取图片名（不包含图片的扩展名）
picPath = '/home/hisense/hiheight/image_input/1.jpg'
imgname = picPath.split("/")[-1].split(".")[0]
print(imgname)  # 1

# 将文件路径和图片名分开
picPath = '/home/hisense/hiheight/image_input/1.jpg'
imgname = os.path.split(picPath)
imgname1 = os.path.split(picPath)[0] + '/'
imgname2 = os.path.split(picPath)[0] + '/' + 'outimg'+ '_' + picPath.split("/")[-1].split(".")[0] + '.png'
imgname3 = os.path.split(picPath)[0] + '/' + 'maskoutimg'+ '_' + picPath.split("/")[-1].split(".")[0] + '.png'
print(imgname)     # ('/home/hisense/hiheight/image_input', '1.jpg')
print(imgname1)    # /home/hisense/hiheight/image_input/
print(imgname2)    # /home/hisense/hiheight/image_input/outimg_1.png
print(imgname3)    # /home/hisense/hiheight/image_input/maskoutimg_1.png

# 将文件名和图片扩展名分开
picPath = '/home/hisense/hiheight/image_input/1.jpg'
imgname = os.path.splitext(picPath)
print(imgname)    # ('/home/hisense/hiheight/image_input/1', '.jpg')
