def stringConnection(params):
    ''' comments block 
    '''
    return "\n".join(["%s=%s" % (k, v) for k, v in params.items()])  #comments line
if __name__ == "__main__":
    myParams = {"server":"mpilgrim", \
                "database":"master", \
                "uid":"sa", \
                "pwd":"secret" \
               }
