Mandeep Singh Grang added the comment: Here is a testcase to reproduce the issue:
> cat test.py import site, sys site.addsitedir('/foo/bar') print (sys.path) This prints just a single instance of '/foo/bar': ['/local/mnt/workspace/python/tst', '/foo/bar', '/usr/local/lib/python36.zip', '/local/mnt/workspace/python/src/Lib', '/local/mnt/workspace/python/src/Lib/plat-linux', '/local/mnt/workspace/python/build/build/lib.linux-x86_64-3.6-pydebug'] Now if we explicitly set PYTHONPATH to include '/foo/bar' > export PYTHONPATH=/foo/bar and then run test.py here is the output: ['/local/mnt/workspace/python/tst', '/foo/bar', '/usr/local/lib/python36.zip', '/local/mnt/workspace/python/src/Lib', '/local/mnt/workspace/python/src/Lib/plat-linux', '/local/mnt/workspace/python/build/build/lib.linux-x86_64-3.6-pydebug', '/foo/bar'] We see that there are duplicate entries for '/foo/bar'. As Wolfgang rightly said the issue comes from the check for "if os.path.isdir(dir)" inside _init_pathinfo() in site.py. On removing this check I no longer see the duplicate entry for '/foo/bar'. But since this is the first bug I am looking at I am not sure of the implications of removing this check. Can someone please confirm that what I see is indeed a failing test case, or is this the intended behavior?
