Question about code

I have a question about what this line of code is doing: addr = i2c.scan()[0].
This line is in the micropython learning module I keep getting a error - IndexError: list index out of range, and am not sure what the problem is.

Please tell us what product you used and where your code came from.

I purchased the Sunfounder Kepler Ultimate Starter Kit and downloaded the libraries - using this link -

I cannot remember right now where I actually got the code from but the project is in the Programming Starter Kit - Project 27 LCD1602 Display with BMP280

Sorry, we didn’t find the corresponding code in Kepler Kit For MicroPython User — SunFounder Kepler Kit for Raspberry Pi Pico W 1.0 documentation.
Perhaps you can provide us with your full code so we can test it.
