连接两个或者更多的路径
特别说明：- 如果各组件名首字母不包含’/’，则函数会自动加上

- 如果有一个组件是一个绝对路径，则在它之前的所有组件均会被舍弃
import os path1 = "home" path2 = "/qtxu" ################ path3 = "20211116" path_joint1 = path1 + path2 +path3 path_joint2 = os.path.join(path1,path2,path3) print(path_joint1) print(path_joint2)结果1

- 如果最后一个组件为空，则生成的路径以一个’/’分隔符结尾
