Python Data Types and Data Structures for DevOps

What are 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 instances (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

Here are the different data types in Python:

1. Numeric types: These include integers, floats, and complex numbers.

2. Boolean type: This is a binary data type that can have one of two values, either True or False.

3. Sequence types: These include strings, lists, and tuples.

4. Dictionary type: This is an unordered collection of key-value pairs.

5. Set type: This is an unordered collection of unique elements.

6. None type: This is a special type in Python that represents the absence of a value.

What is 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 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.

Python also provides some advanced data structures such as stacks, queues, and heaps, which are used to store and manipulate data based on specific requirements. These data structures can be implemented using built-in data structures or custom data structures.

Tasks:

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

In Python, lists, tuples, and sets are three different types of collections used to store a group of related values.

Lists:

• Lists are defined using square brackets [].

• Lists are mutable, which means you can change the values of elements in a list.

• Lists can contain duplicate values.

• Lists are ordered, meaning that the elements of a list are stored in a particular order.

• Lists allow indexing and slicing operations.

Tuple

• Tuples are defined using parentheses ().

• Tuples are immutable, which means you cannot change the values of elements in a tuple.

• Tuples can contain duplicate values.

• Tuples are ordered, meaning that the elements of a tuple are stored in a particular order.

• Tuples allow indexing and slicing operations.

Set

• Sets are defined using curly braces {} or the set() function.

• Sets are mutable, which means you can change the values of elements in a set.

• Sets cannot contain duplicate values.

• Sets are unordered, meaning that the elements of a set are not stored in a particular order.

• Sets do not allow indexing or slicing operations.

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"
   }

1. 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. [Hint: Use keys to built-in functions for Lists]
