The key is leaving out the loop variable. But how does that work? To understand how the Python for loop works, you’ll first need to know a bit about iterables and iterators. What are iterables, iterators and generators? In Python, the for loop operates on objects known as “iterable...

Generators are meant to be used in a range-for loop: Generators implicitly produce two iterators - begin and end which control the execution of the for loop. These iterators should not be handled or accessed manually.When a generator is created, it starts as a lazy task. When its begin ...

If you don't declare a loop variable in the initializer section, you can use zero or more of the expressions from the preceding list in the initializer section as well. The following example shows several less common usages of the initializer and iterator sections: assigning a value to an ex...

or they might not know when they've finished visiting all of them. In this lesson, we're going to look at how TypeScript supports us in building custom ES6 iterators that can be then used by a simple "for..of" loop to ensure we provide an easy to use and reliable API for other ...
but executed in parallel, where multiple threads are in effect all executing this loop until condition() returns false. While it may not be obvious at first glance, we can actually build that with just a few lines of code in terms of Parallel.ForEach. ...
