Solve the following python programming problem given the following code:
def position(keyword = '', url = '', positions = '', topkeyword = '') : 
    'Return the position a provided site is in for a given keyword.' 
    if (not url) : 
        return 'lite value required in column or Config tab.' 
apexdom = apex (url) 
    if topkeyword : 
        keyword = apexdom 
if (not positions) : 
        def gpositions(keyword) : 
            global positions 
            return positions (keyword) 
positions = gpositions (keyword) 
else : 
        if positions : 
            urldict = json.loads (positions) 
            for (thepos, aurl) in urldict.iteritems () : 
                if (apexdom in aurl) : 
                    return thepos
