How can I get file's name from variable with its full path in python?

Question

假设我有a = "C:\\folder1\\folder2\\picture.jpg"如何将变量b分配给文件名及其扩展名：b ='picture.jpg'

Answer 1

Without too many complications, you can just use the os module as follows:

import os
a = "C:\folder1\folder2\picture.jpg"
b = os.path.basename(a)

Which will output what you desire: 'picture.jpg'
