[SOLVED] Trying to pass variable from pandas to sql

I am trying to pass a simple variable (string, list whatever I can get working) in to sql (using jaydebapi to AWS Redshift cluster.

The python/pandas code looks like this at moment. I think the %s is part of the problem:

id = (261894)
df = pd.read_sql_query(
'''
select * from purchases where customer_id = %s
''',
conn, params=[id])

exception is

id = (261894)

Any thoughts on how I can get this to work? Do I need an alternative to %s?
