Python Data Types and Data Structures for DevOps

Already discussed the data types in Python. Please go through this link: Python DataTypes

Data Structures:

Data Structures are a way of organizing data so that it can be accessed more efficiently depending on the situation. Data Structures are fundamentals of any programming language around which a program is built. Python helps to learn the fundamentals 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

Task 1:

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

A list is a mutable object that if you define it once you can add element, remove an element from the list. Tuple is immutable, if you define it once you cannot redefine it.

The list is defined inside square brackets "[]" and Tuple is defined by using parentheses "()".

In comparison to a list and tuple, a set is an unordered collection of data types, due to this nature set does not allow duplicate elements.

List Handson:

Tuple Handson:

Set Handson:

Task 2:

Create the 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"
}

Task 3:

Create a List of cloud service providers.

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

Write a program to add Digital Ocean to the list of cloud_providers and sort the list in alphabetical order.
