Only the base part of startPath is kept, since this routine is typically used with a script's ``__file__`` variable as startPath. The base of startPath is then prepended to all the listed files, forming the output list. Parameters ---------- startPath : string Initial path to use as the base for the results. This path is split using os.path.split() and only its first component is kept. files : list One or more files. Examples -------- >>> full_path('/foo/bar.py',['a.txt','b.txt']) ['/foo/a.txt', '/foo/b.txt'] >>> full_path('/foo',['a.txt','b.txt']) ['/a.txt', '/b.txt'] rcsg|] }tj|qS)ospathjoin).0fbaserX/home/air/segue/gemini/backup/venv/lib/python3.10/site-packages/IPython/testing/tools.py Cszfull_path..) isinstancelistrrsplit)rrrrr full_path&sr"cCstd|tj}|rt|d}d}||fStd|tj}|r.d}t|d}||fStd|tj}|rJt|d}t|d}||fSdS)aParse the output of a test run and return errors, failures.
