Python Beginner Breakthroughs (Dictionaries)

A confession I have is that prior to learning about Python and computer science in general, I had no idea that such a data type existed. When I finally was exposed to it and got to see the extreme amounts of potential that it has, dictionaries quickly became one of the data types that I admired for their structure and versatility. This article will aim to provide a quick overview of what dictionaries are, general rules about how they are to be used, practical ways to use them, and then some quick hypothetical examples of where they can be used.

Commonly referred to in other programming languages as “associative memories” or “associative arrays”, the key principle that the dictionary serves is to map two variables through a parent-child relationship. In this relationship, the parent, syntactically known as the key, and the child, known as the value, represent a key-value pair in the datatype. The most common usage of the dictionary is to have a set of keys that can be called upon and then produce the matching values associated with that key.

The below image is a basic example of a dictionary of some US States and cities representing the key and value pairs. Note that for each value there is a distinct key-value pair that it is connected to.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

Working with Python dictionaries: a cheat sheet

Accessing, editing and looping through dictionary items

Dictionaries in Python are a collection of key-value pairs — meaning every item in the dictionary has a key and an associated value.

If we want to write down prices of some items in a grocery store, normally we will note them on a piece of paper like this:

eggs - 4.99
banana - 1.49
cheese- 4.5
eggplant - 2.5
bread - 3.99

In Python dictionary lingo, the name of each item is “key” and the associated price is “value” and they appear in pairs. We can represent the same in a Python dictionary data structure as follows:

{"eggs": 4.99,
"banana": 1.49,
"cheese": 4.5,
"eggplant": 2.5,
"bread": 3.99}

Notice the differences. In the dictionary

  • each key is within quotation marks because they are strings
  • the associated values are not quoted because they are numeric
  • keys and values are separated by a colon (:)
  • the items are comma-separated
