BACK: Inserting a variable into cur.execute statement

Hello,

I finally got around to trying to implement this code and I am running
into an "IndexError: tuple index out of range" problem.

I am running a function with parameters from a list:

def def_acct_analysis(sht,acct):
print(param[par][0])
print(param[par][1])
sheet ="sheet"+str(sht)
print(sheet)
account = acct
print(account)

par =0 param = [(1,'ACCT0'),(2,'ACCT1'),(3,'ACCT2'),]

for pin param:
def_acct_analysis(param[par][0], param[par][1])

par +=1

#Print statements above output:

1
ACCT0
sheet1
ACCT0

I want to insert the account name 'ACCT0' into my cur.execute but I get
an error with this code:

cur.execute("SELECT COALESCE(SUM(revusd),0) FROM sfdc where stage LIKE 'Win%' AND
saccount = %s", (account,))
wind1 = cur.fetchone()
conn.commit()

I've returned to the psycopg docs but I don't see my error. Can someone
else see it?

Best,

Hagen
