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 program to fetch the indices of true values in a Boolean list

Given a list of only boolean values, write a Python program to fetch all the indices with True values from given list. Let's see certain ways to do this task. Method #1: Using itertools [Pythonic way] itertools.compress() function checks for all the elements in list and returns the list of indices with True values. Python3

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

def my_all_v3 (boolean_list): for item in boolean_list: if not item: return False return True def my_any_v3 (boolean_list): for item in boolean_list: if item: return True return False Although all these approaches are valid, the clear preference in the Python community is the use of all() and any() .

Truth value testing in Python. Python uses the bool type (True and False), but it also evaluates other types, such as numbers and strings, as true or false in conditions such as if statements.. Built-in Types - Truth Value Testing — Python 3.12.1 documentation; The following objects are considered false, as in the official documentation above.

Python Booleans: Use Truth Values in Your Code – Real Python

The Python Boolean type is one of Python’s built-in data types. It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True, while the expression 0 == 1 is False. Understanding how Python Boolean values behave is important to programming well in Python. In this tutorial, you’ll learn how to:

Python | Get indices of True values in a binary list

You can use the list.index() method to find the index of the first occurrence of a True value in the list. Then, you can use a loop to find the indices of all subsequent True values by calling list.index() again on the sublist starting from the next index. Here is an example of how to use this method: Python3

Python | Filter list by Boolean list - GeeksforGeeks

This is because the filtered_list is the only additional data structure created, and its size depends on the number of True values in bool_list. Using a for loop: Initialize a list variable list1 with some integer values, and a Boolean list variable bool_list with some Boolean values. Initialize an empty list variable new_list.

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.
