Add multiple elements to pathlib path

Question

I have a Python pathlib Path and a list of strings, and I'd like to concatenate the strings to the path. This works

from pathlib import Path a = Path("a") lst = ["b", "c", "d"] for item in lst: a = a / item print(a)

a/b/c/d

but is a little clumsy. Can the for loop be replaced by something else?

The constructor of any PurePath subclass accepts an arbitrary number of positional arguments, which means you can just unpack your list of strings.

from pathlib import Path a = Path("a") lst = ["b", "c", "d"] a = Path(a, *lst) print(a) # a/b/c/d

Notice that each argument to Path can be itself a Path instance or a string.

This might be what you are after:

from pathlib import Path a = Path("a") dir_list = ["b", "c", "d"] a = a.joinpath(*dir_list)
