Check if something other than a value in a list in Python-CodePudding

I want to know if there is a value other than a specific value in a list in python, for example: given a list

lst = [0,0,0,0,0,0,0]

How can I check if there is a value other than 0 in it like 1 or 2 or 3 or any number other than 0 and its position? Example :

lst = [0,0,0,0,1,0,0,0]

The check operation should bring a true value saying yes list have value other than 0, that value and its position as 4.

use any made for this

lst = [0,0,0,0,0,1,0]
if any(lst):
    print("Value other than 1")

list comprehension and the any() function:

any([x != 0 for x in lst])

This will check each element x in lst and compare if that element x != 0. It'll return True/False for each. Then any() will return True if everything is True or False if any value is False.

You can use enumerate to get values plus their index in the list.

lst = [0,0,0,0,1,0,0,0]
baddies = [i for i,val in enumerate(lst)]
has_baddies = bool(baddies)
