module 'pymysql._auth' has no attribute 'scramble_old_password

Question

I am getting the following error while connecting to database

                 url = url.URL(
                 drivername='mysql+pymysql',
                 host='xyz',
                 username='abc',
                 password='xghfh@;',
                 database='abcs')

The '@;' at the end of password is converting to %40; How can I avoid the @ getting changed to 40.

mysql+pymysql:/abc:xghfh%40;@abcs/xyz

engine_sql = create_engine(url)

results = engine_sql.execute(sql_query).fetchall()
