Raspberry Pi Pico - First project problem

[ThiNguyen3008]

Hello, I'm a beginner for Raspberry Pi Pico. I cannot run my first project and I don't know why. I'm using Thonny 4.0.1. Can you help me please? Thank you
This is from the book

This is a screenshot of my code

The statements in your while loop need to be indented.

while True:
    led_onboard.value(1)
    utime.sleep(2)
    etc....

I suggest you will save yourself some hair pulling if you just take a small pause to introduce yourself to python (and micropython) . I was perusing youtube before looking at this forum and I remembered youtube showing me some latest videos one of which was a new series on learning micropython so I popped back to get the address of lesson 1. see:

I don't know if its any good but do give it a look. For an into to python I can recommend as being very good for new programmers have a read of the following:

I think .value is for input GPIO. Well, it is for the ESP32.

Try:

while True:
    led_onboard.on()
    utime.sleep(2)
    led.onboard.off()
    utime.sleep(2)

As said, the Code in the While Part must be intendet. This issues the syntax error in the screenshot.
And If you use a Pico W then the inialization of Pin 25 must change to named Pin „LED“ instead -> machine.Pin(„LED“, machine.Pin.OUT)
