Python Data Types and Data Structures for DevOps

Difference between Lists, Tuples and Sets:

1. Lists:

   • Lists are mutable, which means their elements can be modified.

   • Elements in a list are ordered and can be accessed using indices.

   • Lists allow duplicate elements.

   • Lists are created using square brackets [ ] or the list() constructor.

2. Tuples:

   • Tuples are immutable, meaning their elements cannot be modified after creation.

   • Elements in a tuple are ordered and can be accessed using indices.

   • Tuples allow duplicate elements.

   • Tuples are created using parentheses ( ) or the tuple() constructor.

3. Sets:

   • Sets are mutable and unordered collections of unique elements.

   • Sets do not allow duplicate elements.

   • Sets do not have indices, so you cannot access elements by indices.

   • Sets are useful for mathematical operations like union, intersection, and difference.

   • Sets are created using curly braces { } or the set() constructor.

Here are some examples to illustrate the differences:

pythonCopy code# List example
fruits = ["apple", "banana", "orange", "apple"]
fruits[0] = "grape"  # Modifying an element
print(fruits)  # Output: ["grape", "banana", "orange", "apple"]

# Tuple example
colors = ("red", "green", "blue")
# colors[0] = "yellow"  # Error: Tuples are immutable

# Set example
numbers = {1, 2, 3, 3, 4, 5}
print(numbers)  # Output: {1, 2, 3, 4, 5}

✔️Create a Dictionary and use Dictionary methods to print your favorite tool just by using the keys of the Dictionary.

step 1: To create a dictionary and print your favorite tool

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

step 2: Get the key of your favorite tool:

favorite_tool_key = int(input("What is your favorite tool? (1-7): "))

step 3: Get the value of your favorite tool:

favorite_tool = fav_tools[favorite_tool_key]

step 4: Print the favorite tool:

print("Your favorite tool is {favorite_tool}")

The output will be:

What is your favorite tool? (1-7): 4

Your favorite tool is Kubernetes

✔️ 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.

step 1: create a list with the above-mentioned strings

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

step 2: Now add Digital ocean

cloud_providers.append("Digital Ocean")

step 3: Now sort the list in alphabetical order

cloud_providers.sort()

step 4: Now print the list

print(cloud_providers)

The output will be as follows

['AWS', 'Azure', 'Digital Ocean', 'GCP']
