How to get/change the condition of a Select object in SQLAlchemy?

Question

Python

There is an object obtained by calling sqlalchemy.sql.select
q = select("p1", "p2", "p3").select_from("t1").where(column('p1') == 0)
In order to get a list columns specified in select () I can call q.columns.
To get a list of tables with q.froms joins.
How to get a variable from "q" that will contain the entire list of called conditions?
