xxx.split(‘/‘)[-1]解析

origin = 'http://download.tensorflow.org/models/imagenet/inception-2015-12-05.tgz' ###原链接

###split操作符

newname = origin.split('/')[-1] #以‘/ ’为分割f符，-1表示保留最后一段

###额外补充

newname_1 = origin.split('/')[-1] ###保留最后一段

newname_2 = origin.split('/')[:-1] ###取最后一段之前的所有

newname_3 = origin.split('/')[::-1] ###逆序输出

print(filename)

print(filename_1)

print(filename_2)

print(filename_3)

###输出
