Day -14 Task: Python Data Types and Data Structures for DevOp

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 (objects) 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 (class) 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 on 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 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, a Dictionary holds the key:value pair. Key-value is provided in the dictionary to make it more optimized

Tasks:

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

   List:

   • A list is an ordered collection of data with elements separated by a comma and enclosed within square brackets.

   • Lists are mutable and can be modified after creation.

   • Lists can store any type of element.

     

Tuple:

• A tuple is an ordered collection of data.

• Tuples are immutable.

• Tuples are enclosed within parentheses.

  

Set:

• A set is an unordered collection.

• Sets are mutable and have no duplicate elements.

• Sets are represented in curly brackets.

  

1. Create the below Dictionary and use Dictionary methods to print your favorite 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" }

   

2. Create a List of cloud service providers

   • eg. 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.
