The first parameter is a DSN string. You must either use:
 
db2.connect('DATABASE=*LOCAL;UID=username;PWD=password')
 
or use the database keyword argument and leave the dsn (first) argument as
None (default):
 
db2.connect(database=database, username=username, password=password)

Subject: [EXTERNAL] Re: [IBMiOSS] CSV file in the IFS, writing it to a
DB2 file using Python

Hi
Here is the traceback -
Traceback (most recent call last):
  File "read2_csv.py", line 11, in <module>
    conn = db2.connect(database,user,password)
  File "/QOpenSys/pkgs/lib/python3.6/site-packages/ibm_db_dbi.py", line
667, in connect
    return _connect_helper(ibm_db.connect, dsn, user, password, host,
database, conn_options)
  File "/QOpenSys/pkgs/lib/python3.6/site-packages/ibm_db_dbi.py", line
578, in _connect_helper
    options = dict( (k.strip().upper(), v.strip()) for k, v in tokens )
  File "/QOpenSys/pkgs/lib/python3.6/site-packages/ibm_db_dbi.py", line
578, in <genexpr>
    options = dict( (k.strip().upper(), v.strip()) for k, v in tokens )
ValueError: not enough values to unpack (expected 2, got 1)

Line 11 is conn = db2.connect(database,user,password)

In my other script I connect using the default,  conn = db2.connect()
I need to use the user and password parms to connect when the script is
used in production.

It's helpful if you give more information than that. Ideally, you should
provide the entire traceback, but if that's really long, you should at
least give the last few lines. Crucially, they will reveal which exact
line of code triggered the error.

As it stands, I don't see any code that could have produced the error
that you're reporting.

Also, earlier you said you already have a script which gets data from an
Excel workbook into the database. How is *that* script connecting to the
database?
