TypeError: '_Servo' object does not support item assignment

I am testing following (test)program:

from adafruit_servokit import ServoKit
import time

pan = ServoKit(channels=16)
pan.servo[0]=180

I get error in line: pan.servo[0]=180

TypeError: ‘_Servo’ object does not support item assignment
Exiting…
Cleaning up pins

I can’t figure out what is wrong here.

please ignore my message: I found the error (after many hours)
pan.servo[0]=180 should have been pan.servo[0].angle=180
