where the loop is controlled by initializing a variable, setting a loop continuation condition, and defining the iteration step. This structure offers fine control over the loop but can be more verbose compared
But sometimes, the outcomes of a Python snippet may not seem obvious at first sight.Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be...

a generic way to iterate, as follows for ELEMENT in COLLECTION: ... do things ... it's valuable to note that Python works over the notion of iterator for iterations. What decides which value will come and its order/sequentiality it's the iterator. some objects outputs values in a ...
The iterator makes it easy to inspect cell values at each location and neighboring locations. While iterating over a raster, you can read as well as write cell values. RCI is available through the Spatial Analyst module, an extension of the ArcPy Python site package. Iterable access to ...

A generator function looks similar to a regular function but contains the yield keyword instead of return. When a Python program calls a generator function, it creates a generator iterator. Iterators yield a value on demand and pause their execution until another value is required. Let's look ...
Thezip()method is now used to return an iterator. Integers The long data type has been renamed to int (basically the only integral type is now int). It works in roughly the same manner as the long type did. Integers ... GetBeginning Python®: Using Python 2.6 and Python 3.1now with...
This is a guide to Python Substring. Here we discuss the introduction, Substrings in Python, along with the Examples, codes, and Outputs. You may also look at the following articles to learn more – Iterator in Python Python Global Variable ...
