Hi All
I think we can learn from Unix/Linux here. Like python, it has a PATH
variable for finding executables. It also has a command 'which'.
According to the man page
<BEGIN>
DESCRIPTION
which returns the pathnames of the files (or links) which would be
executed in the current environment, had its arguments been given as
commands in a strictly POSIX-conformant shell. It does this by
searching the PATH for executable files matching the names of the
arguments. It does not canonicalize path names.
OPTIONS
-a print all matching pathnames of each argument
<END>
Suppose we had a similar 'which' command in Python. It wouldn't by
itself stop things going wrong. But when they do go wrong, it might
help diagnose the problem.
