How to Use a Generator as an Iterator Iterators in Python are essentially functions that can be looped over. All generators are iterators, but not all iterators are generators. The finer points of iterators are not in the scope of this article, but it is important to know they can be call...
Note: The last example uses Python’s built-in map(), which returns an iterator in which every element is the result of passing the next character in the string to str.isdigit(). This is a useful way to use any() for more complex checks....
We can use the “+” operator in Python to concatenate the lists. Using the “+” operator, you can join two or more lists to form a new list. When you use the “+” operator with lists, a new list is created and the elements of the original lists are copied to the new list in...
Creating databases and tables in SQLite Importing a .csv file into a SQLite database SQLite in Python Note: This tutorial assumes that you are already familiar with the basics of SQL (using any RDBMS) and Python (3). If you want to refresh these skills, the following resources might come...

In order to use a Dataset we need three steps: Importing Data. Create a Dataset instance from some data Create an Iterator.By using the created dataset to make an Iterator instance to iterate through the dataset Consuming Data. By using the created iterator we can get the elements from the...
It is useful when we have to access some objects as iterators. We can do that using generator loops, but those are time-consuming and make the code bulky. Python’s in-built method__iter__()is better for such tasks. As the name suggests, an iterator returns the data values one by ...
Using Python's yield to Create Generator Functions The term generator in Python can refer to a generator iterator or a generator function. These are different but related objects in Python. In this tutorial, the full terms are used often to avoid confusion. Let's explore generator functions fir...
