๐Ÿ“š๐Ÿ Python Data Types and Data Structures for DevOps | #day14 #90daysofdevops

Introduction:

Python, with its simplicity and versatility, offers a wide range of data types and data structures that form the foundation of any program. In this blog post, we'll dive into the world of data types and explore the key differences between three common data structures: Lists, Tuples, and Sets. ๐Ÿš€

Data Types in Python:

Python supports various built-in data types, allowing developers to work with different kinds of data efficiently. Here are some important data types:

  1. Integers (int): Represent whole numbers, both positive and negative.
age = 25
  1. Floating-Point Numbers (float): Represent real numbers with decimal points.
pi = 3.14159
  1. Strings (str): Used for representing text.
name = "Alice"
  1. Boolean (bool): Represents True or False values.
is_student = True

Check the data type in python:

To check the data type of a variable in Python, you can use the built-in function type(). Simply pass the variable as an argument to the type() function, and it will return the data type of that variable. Here's how you can do it:

x = 5
print(type(x))  # This will output: <class 'int'>

name = "Alice"
print(type(name))  # This will output: <class 'str'>

is_student = True
print(type(is_student))  # This will output: <class 'bool'>

eg:

By using the type() function, you can easily determine the data type of any variable in your Python code.

Data Structures in Python:

Data structures help organize and store multiple values efficiently. Let's explore three commonly used data structures: Lists, Tuples, and Sets.

Lists:

Lists are ordered collections of items, and they can hold various data types.

fruits = ["apple", "banana", "orange"]

Lists are mutable, meaning you can change their contents after creation:

fruits[1] = "grape"

Tuples:

Tuples are similar to lists, but they are immutable, meaning their elements cannot be changed after creation.

coordinates = (10, 20)

Tuples are often used for grouping related data together.

Sets:

Sets are unordered collections of unique items.

colors = {"red", "green", "blue"}

Sets automatically eliminate duplicate values, making them useful for tasks like finding unique elements.

Differences Between Lists, Tuples, and Sets:

Let's compare these data structures based on key characteristics:

  1. Mutability:

    • Lists: Mutable (can be changed after creation)

    • Tuples: Immutable (cannot be changed after creation)

    • Sets: Mutable (can be changed after creation)

  2. Order:

    • Lists: Ordered (retain the order of elements)

    • Tuples: Ordered (retain the order of elements)

    • Sets: Unordered (do not guarantee order)

  3. Duplicate Values:

    • Lists: Allow duplicates

    • Tuples: Allow duplicates

    • Sets: Do not allow duplicates (automatically eliminate them)

Tasks:

  1. 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"
     }
    

  1. Create a List of cloud service providers and manupulate it:

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

Conclusion:

Understanding data types and choosing the appropriate data structure is essential for effective programming in Python. Lists, tuples, and sets serve different purposes and offer distinct advantages based on your programming needs. By grasping these concepts, you'll be better equipped to design efficient and robust Python programs. ๐Ÿ“Š๐Ÿงก
