WebPython For Loops A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. WebIf you really wanted to use a for-loop, you could, but the indices guessed by binary search don't go in the sequential order that a for-loop makes convenient. First we might guess the index 12, and then 18, based on some computations. So a while-loop is the better choice. phone booth full movie download https://chansonlaurentides.com
