So if I understand this correctly my new cur.execute would read:
account = 'JPMC'
cur.execute("SELECT SUM(revusd) FROM sfdc where saccount = %s AND stage LIKE
'Commit%';",(account ))
Since you are using a tuple this (account ) would need to be (account,)
per the docs at link previously posted:
"For positional variables binding, the second argument must always be a
sequence, even if it contains a single variable (remember that Python
requires a comma to create a single element tuple):"
and that would translate to
cur.execute("SELECT SUM(revusd) FROM sfdc where saccount = 'JPMC' AND stage LIKE
'Commit%';")
is that right?
Not sure what below is supposed to be about?
Note You can use a Python list as the argument of the IN operator using the
PostgreSQL ANY operator.
ids = [10, 20, 30]
cur.execute("SELECT * FROM data WHERE id = ANY(%s);", (ids,))
Furthermore ANY can also work with empty lists, whereas IN () is a SQL syntax
error.

Hello,
I'd like to use a variable for 'Big Company' (e.g. account) or where =
statements generally in my cur.execute statements:
cur.execute("SELECT SUM(revusd) FROM sfdc where saccount = 'Big Company' AND stage
LIKE 'Commit%';")
commitd1 = cur.fetchone()
conn.commit()
but I don't know the proper syntax with the cur.execute statement to use a
variable.

I imagine others do - thanks!
Best,
