Ian Shields added the comment:
Regarding last comment. I had missed the comment in documentation fo
os.path.join "Join one or more path components intelligently. If any component
is an absolute path, all previous components (on Windows, including the
previous drive letter, if there was one) are thrown away, and joining
continues". So the issue is really the behavior of os.path.join where the
intelligence in the joining does not recognize that "~" is usually expanded to
an absolute path. Consider the following Bash commands:
[ian@attic4 testpath]$ pwd
/home/ian/testpath
[ian@attic4 testpath]$ echo $(cd ~/testpath/..;pwd)
/home/ian
[ian@attic4 testpath]$ cd /home/ian/~
bash: cd: /home/ian/~: No such file or directory
Now consider some Python
>>> os.getcwd()
'/home/ian/testpath'
>>> os.path.join(os.getcwd(), "/home/ian")
'/home/ian'
>>> os.path.expanduser("~")
'/home/ian'
>>> os.path.join(os.getcwd(), "~")
'/home/ian/testpath/~'
>>> os.path.expanduser(os.path.abspath("~"))
'/home/ian/testpath/~'
>>> os.path.abspath(os.path.expanduser("~"))
'/home/ian'
I find the Python behavior rather odd. I cna live with it now I know about it,
but if it is really intentional it would help to document this rather odd
behavior somewhat better.
