Last week we looked at how to setup an Apollo server to serve graphql requests. We went through the setup by defining a TemplateStringArray for the schema and defining functions in an object map for the resolvers. In this week post, we will look at how to simplify this two areas by leveraging Typescript features using typegraphql package.

A data class is a class which is identified by the value stored in their attributes. The most common way of holding values in Python is via tuples. Data classes make is easier to construct a class with a name and meaning while keeping the value aspect in term of equality. In today’s post we will see how we can define data classes using the dataclass decorator from the dataclasses module.

Python itertools module provides a set of iterator blocks that can be used to combine iterators into a new iterator which will apply some modifications during the iteration of the sequences. For example building blocks like cycle allows infinitely cycling through a sequence, another example is groupby which provides a new iterator giving the groups on each iteration. In today’s post, we will look at some of the functions provided by itertools with examples.

Python comes with general purpose datatypes like dict, list or set. Those types are commonly used everywhere with the best tradeoff in term of performance and application scope. But there are times where we might see ourselves repeating a specific implementation, for example counting values while storing them in a dict is one of those cases. To cater for those repeated scenarios, the collections module gives us access to alternative types that can be used for specialized purposes. In today’s post we will look at some of those types with examples.

Sorting lists in Python is very easy provided that we know how to use the sorting functionalities. Python comes with list.sort() and sorted() function, both behaving somewhat in the same way with the only different that the first one sorts in place whereas the later returns a new sorted list without altering the existing list. In today’s post we will look at different sorting scenarios and how we can achieve them using Python sort functionalities.
