Strange argument count error

[rowan_bradley]

I am trying to call a function in a library written by someone else. Here is my code:

import growattServer
import datetime
import time
from datetime import date
import getpass
import json
import sys, getopt
import shutil
from enum import IntEnum

# set up variables
user_name = "rowan.bradley"	# Server username
user_pass = "xxxxxxxxxxxxx" # server password
outFolder = "/growatt"
outPrefix = "growatt-"
outSuffix = ".json"

class Timespan(IntEnum):
    hour = 0
    day = 1
    month = 2

api = growattServer.GrowattApi(False, "hue73jhns83je93jed723uj2")
login_response = api.login(user_name, user_pass)
today = date.fromtimestamp(time.time())
inverter_detail = api.inverter_detail('OOCTCHT07L', today) 
print("inverter_detail = ", inverter_detail)

This what happens when I run this:

D:\XPS_8700 Extended Files\Users\RowanB\Documents\Inetpub\www.sylvesterbradley.org\public_html>python -O growatt3.py
Traceback (most recent call last):
  File "D:\XPS_8700 Extended Files\Users\RowanB\Documents\Inetpub\www.sylvesterbradley.org\public_html\growatt3.py", line 26, in <module>
    inverter_detail = api.inverter_detail('OOCTCHT07L', today)
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: GrowattApi.inverter_detail() takes 2 positional arguments but 3 were given

D:\XPS_8700 Extended Files\Users\RowanB\Documents\Inetpub\www.sylvesterbradley.org\public_html>

Why does it say that three arguments were given although it is clear from the call that there were only 2? How do I get this call to work?

Thank you - Rowan

It take only one argument inverter_id Methods.

inverter_detail = api.inverter_detail('OOCTCHT07L')

So is it ok for you to post the server password?
I did remove it from your last Thread.

This is 2 arguments:

api.inverter_detail('OOCTCHT07L')

Because python passes api as the first argument.:

api.__class__.inverter_detail(api, 'OOCTCHT07L')

I think it's OK. I included it so that people could try the code and see what is wrong (which one person has already done). I did think about it before including it.
