Debugging scripts basics

[bako]

So, I'm mainly a BASH scripter looking to jump into the Python boat.

What's the equivalent to bash -xv when running a python script? Rather than bug people necessarily, I need help on trying to troubleshoot the logic of a python script.

I've already read https://python-forum.io/Thread-Basic-Sim...tracebacks

Scenario:
I'm trying to get the value of channel 7 on a Raspberry Pi to figure out if the value needs to be changed. From my understanding, GPIO.input should output a 1 or a 0. But, when running the script I get nothing. I've even tried usind -d and -vv. But all I get are entries for Importing modules and cleanups.

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
GPIO.setup(7, GPIO.IN)
GPIO.setup(7, GPIO.OUT)

GPIO.input(7)
time.sleep(4)

GPIO.cleanup()
