设置pathlib Path的name属性 class

Question

I was wondering if there was a neat way to set the Path.name attribute.

My code basically looks like this:

from pathlib import Path
mypath = Path("this/is/a/path")
mypath.name == "path"
>>> True
#now I want to change the name, or the top level folder name in the path
mypath.name = "panda" #does not work, since its a property

#only way I can think of:
mypath = mypath.parent.joinpath("panda")

this is pretty ugly, especially since I am actually in a class with longer names for everything. Is there a setter for the name attribute? I cant find any, but I also didnt find the opposite...

Answer 1

You can use the with_name method which would be cleaner and exactly what the method is designed for.

However, it is not overwriting the name attribute which is impossible because it is immutable. It returns a new Path object so you will have overwrite mypath or save it as something new.

mypath = mypath.with_name('panda')
