As part of a post on python-ideas, I wanted to knock together a quick
little script that "imports" a file based on its name, in the same way
that the Python interpreter will happily take an absolute pathname for
the main script.
Is it imp.load_source() that you are looking for?
I'm using a similar thing for a plugin system, the plugins are stored
with a fixed filename in a folder structure. The code looks like
this(stripped down):
import imp
# folder is the path to the file, under which pluginmain.py
# contains the code
namespace = 'plugin{0}'.format(plugincount)
plugincount = plugincount + 1
# try to import the file and exec the init function
# if anything fails, set success=False, errorpos and errorinfo
# add path to the plugin into import path
oldsyspath=sys.path[:]
sys.path.insert(0, folder)
# load module
module = imp.load_source(namespace,os.path.join(folder,'pluginmain.py'))
Modifying sys.path is only necessary because the file could further
import modules from the same path.
