python - Getting indices of True values in a boolean list - Stack Overflow

I have a piece of my code where I'm supposed to create a switchboard. I want to return a list of all the switches that are on. Here "on" will equal True and "off" equal False.So now I just want to return a list of all the True values and their position. This is all I have but it only return the position of the first occurrence of True (this is just a portion of my code):

Python's all (): Check Your Iterables for Truthiness

In the first example, the input list contains regular Python objects, including a string, a number, and a dictionary.In this case, all_true() returns False because the dictionary is empty and evaluates to false in Python. To perform truth value testing on objects, Python has an internal set of rules for objects that evaluate as false:. Inherently negative constants, like None and False

{AND, OR, NOT} How to Apply Logical Operators to All List ... - Finxter

The challenge in the puzzle is to know that Python comes with implicit Boolean type conversion: every object has an associated Boolean value.Per convention, all objects are True except “empty” or “zero” objects such as [], '', 0, and 0.0.Thus, the result of the function call all([True, True, 0]) is False..

python - every element of list is True boolean - Stack Overflow

I don't know python very well, but why can't you just scan the list and count how many elements are true, then if you find only one the answer is "yes", otherwise is "no". These are functions you usually write in the first 2-3 months of learning programming basics.

Python | Get indices of True values in a binary list

Time complexity: O(n) where n is the length of the list. Auxiliary space: O(1), as the memory used is constant and does not depend on the size of the list. Method #3 : Using itertools.compress() compress function checks for all the elements in list and returns the list of indices with True values. This is most Pythonic and elegant way to perform this particular task.
