Hi DenesL,

This is a bit tricky in Python, but it can be done. Here's a function that does it: def getName(obj, namespaces=None, findAllNames=False): ''' Returns the name(s) associated with a given object. @param obj The object whose name you would like to know @param namespaces An ordered list of namespaces that you would like to search for the inputed object. Valid namespaces include: globals(), locals(), and vars(some_object). If set to None (the default) then the globals() namespace will be assumed. You can also directly input a single namespace. @param findAllNames If False (the default) then this function will return the first valid name that it finds. If True then this function will return a complete list of all names it found in all of the namespaces. @return The first valid name that it finds in the given namespaces. If findAllNames is True, then it returns a list of all names found. If nothing is found, returns None. ''' if (namespaces == None): namespaces = [globals()] #if a dictionary was inputed for namespaces if (type(namespaces) == dict): #then this is probably because the user only needed to input #one namespace, and didn't place it in a list namespaces = [namespaces] result = [] for namespace in namespaces: for key,value in namespace.iteritems(): #if the given namespace object matches the inputed object if value is obj: if (findAllNames == False): return key else: result.append(key) if (len(result) > 0): return result else: return None --- Try typing getName(db) and it should return the string 'db' --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "web2py Web Framework" group.
