simplest way to visit 3 subdirectories with a command?

[dmitrey]

hi all,
could you inform how to compose a py-file (for soft installation),
that will visit 3 subdirectories (eg subdir1, subdir2, subdir3) and
invoke a command "python setup.py install" in each subdirectory?
I know there should be a simple solution available in Python
documentation, but I have an awful lots of other things to be done, so
could someone write these several lines of code?

Thank you in advance, D.

If you're executing "python setup.py install", that sounds like
you're operating at the shell level, not within python. In which
case, I'd just use my shell's iteration capabilities:

# running bash on a *nix-like OS
bash$ for dir in subdir1 subdir2 subdir3; do pushd $dir;
python setup.py install; popd; done

# running within Win32's cmd.exe
c:\temp\> for %f in (subdir1 subdir2 subdir3) do pushd %f &
python setup.py install & popd

or something of the sort. Remember in Win32 that the variables
have to be escaped if you put them in a batch file ("%%f" instead
of "%f")
