Incorrect.

I set both $PATH and $PYTHONPATH in .bashrc, and after some testing it
seems that bash doesnt expand tilde at the time of reading .bashrc if
its enclosed in quotes (which I currently do), but it is expanded on
the fly (works with tab-completion etc). So the conclusion is that
Python doesnt expand tilde in $PYTHONPATH, but relies on that the
variable is already expanded by the shell. Hence that $PYTHONPATH
doesnt behave like $PATH.

1)
   $ grep PATH .bashrc
   export 
PATH="~/profile/bin:/usr/local/bin:/usr/bin:/usr/games:/usr/bin/X11:/bin"

   $ echo $PATH
   ~/profile/bin:/usr/local/bin:/usr/bin:/usr/games:/usr/bin/X11:/bin

2)
   $ grep PATH .bashrc
   export 
PATH=~/profile/bin:/usr/local/bin:/usr/bin:/usr/games:/usr/bin/X11:/bin
   $ echo $PATH
   /home/hh/profile/bin:/usr/local/bin:/usr/bin:/usr/games:/usr/bin/X11:/bin

Both $PYTHONPATH and $PATH can use $HOME when exporting, since that is
always expanded, with or without quotes.

Bug#321973: python2.3: PYTHONPATH doesn't expand ~

[Henrik Holmboe]

Package: python2.3
Version: 2.3.5-3
Severity: minor

*** Please type your report below this line *** According to section
PYTHONPATH should behave like PATH according to section 6.1.1 (see URL
below) of the Python Tutorial. But I have found that it doesnt
properly expand ~ (tilde) to the home directory.

A workaround is to use ${HOME} instead of ~, but both should work as
advertised.
