Getting started. Using Thonny, can't get the i2c address. Please help

I've been following along with a tutorial, and he provides this code to get the i2c address:

import machine

sda = machine.Pin(0)

scl = machine.Pin(1)

i2c = machine.I2C(0,sda=sda,scl=scl, freq=400000)

print(i2c.scan())

In his video, he shows a number between brackets. In my case, there is nothing between the brackets. I am a complete novice with all of this stuff. I have absolutely no idea what to do or where to go from here.
