Python Data Types [Day 14 Task]

Python Data Types:

• 1.Difference between List, Tuple, and Set

  1. A list is an ordered collection of similar or different types of items separated by commas and enclosed within brackets [ ].

  The Set is an unordered collection of unique items. Set is defined by values separated by commas inside braces { }.

  Tuple is an ordered sequence of items same as a list. The only difference is that tuples are immutable. Tuples once created cannot be modified.

• 2. A list refers to a data structure of a non-homogenous type that functions to store various elements in columns, multiple rows, and single rows.

  A tuple also refers to a data structure of the non-homogenous type that functions to store various elements in columns, multiple rows, and single rows.

  A set also refers to a data structure of the non-homogenous type, but it stores various elements in a single row.

• 3. Lists allow various duplicate elements.

  Tuple allows various duplicate elements.

  The set does not allow any duplicate elements.

• 4. We can create a list using the list() function.

  We can create a tuple using the tuple() function.

  We can create a set using the set() function.

• 5. List is mutable. It means that a user can make any changes to a list

  Tuple is immutable. It means that a user can’t make any changes to a tuple.

  The Set is mutable. It means that a user can make any changes to a set.

• 6. If we want to create an empty list, we use: l=[]

  If we want to create an empty tuple, we use:

  t=()

  If we want to create an empty set, we use:

  a=set()

  b=set(a)

• 2. 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" }

  First, create a dictionary and then print it. To execute a python file python followed by file name.

  

  3. Create a List of cloud service providers eg.

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

  To access items from a list, we use the index number (0, 1, 2 ...). So here I print Azure [2]

  

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

  Just add Digital_Ocean to the list and sort(by default it is set to ascending order) the cloud provider by using the sort() function.
