The [...] loop is similar to an [...] statement: it executes the code inside of it if some condition is true. The difference is that the [...] loop will continue to execute as long as the co...

The condition is the expression that decides whether the loop is going to continue being executed or not. There are 5 steps to this program: 1. The [...] variable is set to [...] 2. The [...

Inside a [...] loop, you can do anything you could do elsewhere, including arithmetic operations.

A common application of a [...] loop is to check user input to see if it is valid. For example, if you ask the user to enter [...] or [...] and they instead enter [...] , then you should re...

An infinite loop is a loop that never exits. This can happen for a few reasons: 1. The loop condition cannot possibly be false (e.g. [...] ) 2. The logic of the loop prevents the loop condi...

The [...] is a one-line statement that means "exit the current loop." An alternate way to make our counting loop exit and stop executing is with the [...] statement. * First, create a [......

Something completely different about Python is the [...] / [...] construction. [...] / [...] is similar to [...] / [...] , but there is a difference: the [...] block will execute anytime...

Now you should be able to make a game similar to the one in the last exercise. The code from the last exercise is below: [...] In this exercise, allow the user to guess what the number is [......

An alternative way to loop is the [...] loop. The syntax is as shown in the code editor. This example means "for each number [...] in the range 0 - 9, print [...] ".

This kind of loop is useful when you want to do something a certain number of times, such as append something to the end of a list.

Using a [...] loop, you can print out each individual character in a string. The example in the editor is almost plain English: "for each character [...] in [...] , print [...] ".

String manipulation is useful in [...] loops if you want to modify some content in a string. [...] The example above iterates through each character in [...] and, in the end, prints out [...

Perhaps the most useful (and most common) use of [...] loops is to go through a list. On each iteration, the variable [...] will be the next value in the list. So, the first time through, it ...

You may be wondering how looping over a dictionary would work. Would you get the key or the value? The short answer is: you get the key which you can use to get the value. [...] 1. First, we c...

A weakness of using this for-each style of iteration is that you don't know the index of the thing you're looking at. Generally this isn't an issue, but at times it is useful to know how far into ...

It's also common to need to iterate over two lists at once. This is where the built-in [...] function comes in handy. [...] will create pairs of elements when passed two lists, and will stop ...

Just like with [...] , [...] loops may have an [...] associated with them. In this case, the [...] statement is executed after the [...] , but only if the [...] ends normally—that is, no...

As mentioned, the [...] block won't run in this case, since [...] executes when it hits [...] .

To wrap up this lesson, let's create our own [...] / [...] statement from scratch.
