In the following example, we loop through a list of numbers, and use the variable digit to hold each number in turn: Strings in Python are considered “sequences” — they can be iterated over ...

Perhaps not. Consider [Tushar Sadhwani] who wanted to create a classic C-style for loop inside of Python. He did it, and the journey is perhaps more interesting than the result. First, you can’t ...

If you’ve ever written any Python at all, the chances are you’ve used iterators without even realising it. Writing your own and using them in your programs can provide significant performance ...

whatever is a dummy variable that you can replace with other variables. Be sure to indent the statements to repeat in the loop. We need to have at least one condition to implement the loop and make ...

But as a fairly experienced Python developer, Crystal code still looks crystal clear! Here’s an example of a recursive loop that calculates factorials: Factorial calculation in Crystal.

Let’s look at a few other elements that are key to asynchronous applications in Python. The asyncio library creates and manages event loops, the mechanisms that run coroutines until they complete.

Python works well on both of these platforms because of its flexibility, facilitated by its extensive list of built-in functions. By using the open() function and a simple loop, you can cycle ...
