python - Filtering a list based on a list of booleans - Stack Overflow
But if you need to use list anyway, you have (using NumPy solution) create np.array from both lists, use boolean indexing and finally converting array back to list with tolist() method. To be precise, you should include those objects creation into time comparison. Then, using itertools.compress will be still the fastest solution.

Boolean list initialization – Python - GeeksforGeeks
Let's explore several ways to initialize a boolean list in Python. The most efficient way to initialize a boolean list with identical values is by using list multiplication. This approach creates a list with a predefined length and assigns the same boolean value to all elements. Explanation:

Python Booleans - W3Schools
Booleans represent one of two values: True or False. In programming you often need to know if an expression is True or False. You can evaluate any expression in Python, and get one of two answers, True or False. When you compare two values, the expression is evaluated and Python returns the Boolean answer:

Filtering a List with Boolean Values in Python 3 - DNMTechs
Python provides a concise way to filter a list using boolean values using a technique called list comprehension. List comprehension allows us to create a new list by iterating over an existing list and applying a condition to each element. In this example, we have a list of numbers.

Append Boolean to List in Python (4 Examples) - Statistics Globe
The most common way to append a boolean to a list is to use the append () method. See the implementation below. As seen above, the boolean value, True, has been appended to the end of my_list. One might also be interested in appending multiple boolean values to a list. You can implement this easily using the extend () method as follows.

Python Booleans: Use Truth Values in Your Code
Watch it together with the written tutorial to deepen your understanding: Python Booleans: Leveraging the Values of Truth. 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.

5 Best Ways to Initialize Boolean Lists in Python - Finxter
Here we’ll explore methods to efficiently create a list of boolean values based on a given size. For example, creating a list with ten elements all initialized to True. This method involves multiplying a single boolean value by the desired list length. It’s a quick and pythonic way to create a list where all the elements are the same.

Top 4 Ways to Apply Logical Operators to All Elements in a Python List
Consider the following example where you have a list of boolean values and want to apply a logical operation across all of them. Here’s a less-than-ideal solution that might come to mind: if len(boolean_list) > 1: return boolean_list[0] and apply_and(boolean_list[1:]) else: return boolean_list[0] While this works, it’s not very pythonic.
