bool value of a list in Python - Stack Overflow

In most cases, you only need to check whether the list is empty or not, you don't really need a boolean value. Python can see that you're evaluating an if statement and it calls bool() itself. If you really then a boolean value (for example, as output) then bool(my_list) is fine of course.

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 also has many built-in functions that return a boolean value, like the isinstance() function, which can be used to determine if an object is of a certain data type: Check if an object is an integer or not: Exercise? What is this? print(5 > 3)?

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.

Python | Filter list by Boolean list - GeeksforGeeks

Define a list bool_list containing the boolean values to filter the list by. Use a list comprehension to iterate over both lists simultaneously using the zip () function. Check if the current element of my_list should be included in the filtered list by checking the corresponding boolean value in bool_list.

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

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): x = [self.states.index(i) for i in self.states if i == True] This only returns "4" Use enumerate, list.index returns the index of first match found.

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.
