a solution problem available python 2, uses imp module deprecated in python 3. imp has been replaced importlib works file based imports. specifically, importlib.import_module requires file name - not string or file handler. i made workaround dumping contents of url file , importing it def initlog(): modulename = '_mylogging' try: import _mylogging except importerror: r = requests.get('http://(...)/mylogging.py') open(modulename+'.py', "w") f: f.write(r.text) finally: import _mylogging return _mylogging.mylogging().getlogger() but avoid intermediate file. putting security, network performance , availability issues aside - is there way feed string importlib ? (or file handler, in case use io.stringio ) you can adapt exactly same answer 3.x, using the replacement imp.new_module : from types import moduletype foo = moduletype('foo') and the replaceme...
