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 perfo… ...

This post explains how to use loops in Python. You'll learn FOR loops, WHILE loops, BREAK, CONTINUE and more. A crucial skill for coding!

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.

For our first program, let's print a string or text in the console, also known as the command line interface. For that, we'll use the print() function in Python. Write this in your code editor: ...

A generator is a kind of object that knows how to behave inside a Python for loop. (In other words, it implements the iteration protocol.) When put inside such a loop, the function will start to run.

Julia includes a REPL (read-eval-print loop), ... Python and C included, the first element of an array is accessed with a zero—e.g., string[0] in Python for the first character in a string.
