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):. self.states = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False ...

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] ... In the worst case, when all elements of the boolean list are True, the function creates a list of size N, where N is the length of the boolean list. Therefore, the space complexity is O(N) where N is the length of the boolean list. ...

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; Numeric types with a zero value, like 0, 0.0, 0j, Decimal("0"), and Fraction(0, 1); Empty sequences and ...

Boolean list initialization – Python | GeeksforGeeks

Let's explore several ways to initialize a boolean list in Python. Using List Multiplication. ... # Initialize a boolean list with 5 elements all set to True a = [True] * 5 print (a) Output [True, True, True, True, True] Explanation: This method directly multiplies the boolean value with the desired list size. It is ideal when we want to create a list of True or False values in a fixed size.

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, ... For the same reason you can’t assign to +, it’s impossible to assign to True or False. Only two Python Boolean values exist. A Boolean operator with no inputs always returns the same value. Because of this, True and False are the only two Boolean operators that don’t take inputs.
