Pymysql cant connect Amazon RDS host, but same host is accessible through mysql workbench

问题

I am using pymysql to connect to Amazon RDS and it fails with :

 db = pymysql.connect(host=Host, user=User, password=Pswd, db=DBN, charset='utf8mb4', cursorclass=pymysql.cursors.DictCursor,local_infile=True)
 File "/usr/local/lib/python2.7/dist-packages/pymysql/err.py", line 107, in raise_mysql_exception
    raise errorclass(errno, errval)
pymysql.err.OperationalError: (1045, u"Access denied for user 'p_cs'@'xx.xx.xx.xx' (using password: YES)")

However If i try to connect to the same host with mysql workbench, I am able to! Any help on what can be the connectivity issue??
