I have a dataframe like,

BeautifulSoup returns None several among valid results, which are the movie titles. Here's my code:

I need a regex to match exactly 'AB' chars set at the beginning or at the end of the string and replace them with ''. Note: it should not match parts of that chars set, only if it occurs whole.

1. So if I have 'AB Some AB company name AB', it should return 'Some AB company name'.
2. If I have 'Balder Storstad AB', it should remove only 'AB' and not the 'B' at the beginning because it is not whole 'AB', only the part of it.

What I tried is:

In my iOS quiz app you get 15 seconds to answer a question. If answered correctly, a second view controller appears than is dismissed from the click of the button on the second view controller and the first view controller reappears with a new question to be answered. However, the countdown timer is starting as soon as you click the answer to the question and not when you click the button on the second view controller to dismiss the second view controller. I want the countdown timer to reset soon as the button on the second view controller is dismissed and shows the original view controller with a new question. What's the best way to make this happen?

Here's my code (first view controller):

My following code displays a question and its matching answer by making an array of keys and values from a dictionary and making sure both arrays have the same index that is pulled. However after a question and its answers are randomly selected I want to remove them permanently from their respective arrays until all the other items in the array have been displayed. Simply put, how can I make sure a question and set of answers are not shown again until all the items are shown or until the user gets an answer wrong? As of now my code only makes sure the same random index isn't chosen twice in a row when I want to make sure it isn't shown twice at all.

Here is my code (swift for iOS):

I am developing a iOS quiz app where the questions and answers are stored in a dictionary of type [String : Array] where the questions are the keys and the answers to that question are its values. I have found out how to randomly display question by creating an array of the dictionary's keys and setting a label text as the the random chosen key. However I am having trouble setting the values of the chosen key as title's for the buttons? There are four values per key and four buttons, what would be the most efficient and simplest way to display the answer values as titles as buttons?

Here is my code (when I run the simulator the four buttons titles just say "button" even though I have a setTitle function in my code):

I am developing a quiz app for iOS and I keep the questions in an array and the answers in another array. So far I have been able to have a label display a random question from the question array with arc4random. However when I try to set up buttons to display random answer choices they don't match the assigned question. For example, the question at index = 0 in the question array goes with the array of answers at index = 0 in the answers array and so. How can I make it to where whenever a random question is generated the correct answers display with (in other words how do I make sure they both always have a matching index that is pulled by the arc4random method or whatever method)?

Here is some of my code:
