[Python-Dev] PEP 273: Import Modules from Zip Archives

[Tim Peters]

[James C. Ahlstrom]
> The zip archive name is always inserted as the second item
> in sys.path.  The first always seems to be ''.

Running p.py:

import sys
print `sys.path[0]`


on Windows gives:


C:\Code\python\PCbuild>python p.py
''

C:\Code\python\PCbuild>cd ..

C:\Code\python>pcbuild\python pcbuild\p.py
'pcbuild'

C:\Code\python>pcbuild\python \code\python\pcbuild\p.py
'\\code\\python\\pcbuild'

C:\Code\python>cd pcbuild

C:\Code\python\PCbuild>python .\p.py
'.'

C:\Code\python\PCbuild>move p.py ..\lib
C:\CODE\PYTHON\PCBUILD\p.py => C:\CODE\PYTHON\lib\p.py [ok]

C:\Code\python\PCbuild>python ..\lib\p.py
'..\\lib'

C:\Code\python\PCbuild>

That is, the first entry is the path (relative or absolute!) to the
directory in which the script being executed lives.
