os.path.basename(file) vs file.split("/")[-1]

Question

I need to extract seq_00034 from a file path like

    file = "/home/user/workspace/data/seq_00034.pkl"

I know 2 ways to achieve it:

method.A

    import os
    seq_name = os.path.basename(file).split(".")[0]

or

method.B

    seq_name = file.split("/")[-1].split(".")[0]

Which is safer/faster?

(taking the cost of import os into account)

Is there a more elegent way to extract seq_name from given path?

Answer 1

I think the more elegant way would be by using the pathlib.Path.stem() method

import pathlib

filename =  "/home/user/workspace/data/seq_00034.pkl"
path = pathlib.Path(filename)

print(path.stem)
