Not sure what you mean. Never been in the same room as a Raspberry Pi either though, I might be missing something.
To blink an LED on pin13 in python with libgpiod:
#!/usr/bin/env python3
#this script will blink an LED attached to pin 13 (chip# 0, linux# 9)
import gpiod
import time
chip = gpiod.Chip('0') # set the chip number
lines = chip.get_lines([9]) # setthe line number
lines.request(consumer='spam', type=gpiod.LINE_REQ_DIR_OUT, default_vals=[0]) # set direction and value
# Not sure what 'consumer' does, so I just set it to nonesense. The guide I folowed did the likewise.
# here's the loop
try:
for i in range(10):
lines.set_values([1])
time.sleep(0.25)
lines.set_values([0])
time.sleep(0.25)
finally:
lines.release()
chip.close()
