Try, the following:

class getQryStr:
    def __init__(self,op):
        print op
        self.x = 'd'
    def returnStr(self, *args):

        print '%s %s me mad' % (self.x,args)
        if self.x == 'd':
            s = Template("delete from columndef where tblid = $tblid and
colname = $colname")
        else:
            return 'nope' #this else is just for illustration and
testing

        d = dict(tblid=t.tblid.getText(), colname=t.colName.getText())

        print s.substitute(d)

        return s
