I'm writing a price parser. I need to do the equivalent of perl's $$var to instantiate a class where $car is the class_name.I'm passing 'Ebay' or 'Newegg' or 'Amazon' via cmd-line. I have a module named ebay.py and a class called Ebay (price parser). I do something like: \> main.py ebay motherboard and this does: module = __import__(module_name) but now i need to instantiate the class - right now I do: instance = module.Ebay(module_name, product) how do i replace the 'Ebay' bit with a variable so that I can load any class via cmd line. class Load(object): def __init__(self, module_name, product): try: module = __import__(module_name) instance = module.Ebay(module_name, product) except ImportError: print("Can't find module %s" % module_name)
Ebay = geattr(module, 'Ebay') or klass = getattr(module, module_name.capitalize()) instance = klass(module_name, product) Cheers, Cameron Simpson <c...@zip.com.au> -- https://mail.python.org/mailman/listinfo/python-list
