Python Data Types and Data Structures for DevOps

New day, New Topic.... Let's learn along 😉

Data Types

Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data.
Since everything is an object in Python programming, data types are actually classes and variables are instance (object) of these classes.
Python has the following data types built-in by default: Numeric(Integer, complex, float), Sequential(string,lists, tuples), Boolean, Set, Dictionaries, etc

To check what is the data type of the variable used, we can simply write: your_variable=100 type(your_variable)

Data Structures

Data Structures are a way of organizing data so that it can be accessed more efficiently depending upon the situation. Data Structures are fundamentals of any programming language around which a program is built. Python helps to learn the fundamental of these data structures in a simpler way as compared to other programming languages.

Lists Python Lists are just like the arrays, declared in other languages which is an ordered collection of data. It is very flexible as the items in a list do not need to be of the same type
Tuple Python Tuple is a collection of Python objects much like a list but Tuples are immutable in nature i.e. the elements in the tuple cannot be added or removed once created. Just like a List, a Tuple can also contain elements of various types.
Dictionary Python dictionary is like hash tables in any other language with the time complexity of O(1). It is an unordered collection of data values, used to store data values like a map, which, unlike other Data Types that hold only a single value as an element, Dictionary holds the key:value pair. Key-value is provided in the dictionary to make it more optimized

Tasks

Give the Difference between List, Tuple and set. Do Handson and put screenshots as per your understanding.

List

The list can be represented by [ ]

The list allows duplicate elements

A list is mutable i.e we can make any changes in the list.

Tuple

Tuple can be represented by ( )

Tuple allows duplicate elements

A tuple is immutable i.e we can not make any changes in the tuple.

Set

The set can be represented by { }

The Set will not allow duplicate elements

A set is mutable i.e we can make any changes in the set, its elements are not duplicated.

Create below Dictionary and use Dictionary methods to print your favourite tool just by using the keys of the Dictionary.

fav_tools =
{
  1:"Linux",
  2:"Git",
  3:"Docker",
  4:"Kubernetes",
  5:"Terraform",
  6:"Ansible",
  7:"Chef"
}

Create a List of cloud service providers eg.

cloud_providers = ["AWS","GCP","Azure"]
