Can't insert from python client into cratedb

Using the python client.

I'm getting a connection back and then submitting a insert statement with parameter arg data hard coded. Getting an error however.

from crate import client
con = client.connect("http://webservicesbigmac.richmond.edu:4200")
cursor = con.cursor()
print cursor
cursor.execute("INSERT INTO logs (client_ip) VALUES (?)", ("66.249.67.49"))

I can run this query in the crash client and it works

cr> INSERT INTO logs (client_ip) VALUES ('66.249.67.49');

INSERT OK, 1 row affected (0.001 sec)

I'm sure I'm doing something wrong, just not certain what it is.

this stack trace

I'm guessing (never used cratedata), but from one of the select examples, it appears that the bind variable list needs to be a tuple. You're only passing in a single value - try: ("66.249.67.49", ) Note the comma
