Day 27 Of Documenting My Learning Journey

What I learnt Today

1. How to define dictionaries using dict constructor and curly braces {}
2. How to access elements in a list usin the .get method() and variable name with brackets[]
3. How to add and update elements in dictionary
4. How to loop through keys , values and both keys and values using a for loop.

On what I learnt Today
Assumption: We have a dictionary of the name Person.

Syntax:

1. Defining: person = { "name" : "James" , "age" : 23 , "Occupation" : "Engineer" }

2. Accessing Elements = print(person["name"]) OR print(person.get("name"))

3. Adding Elements in a Dictionary
   person["status"] = "Graduated"

4. Updating elements in a Dictionary.
   person["age"] = 20

5. Removing an Element from a Dictionary
   person.pop("status")

6. Looping through respecive keys
   for key in person:
   print(key)

7. Looping through respective Values
   for value in person.values():
   print(value)

8. Looping through respective keys and Values
   for key , value in person.items():
   print(f"{key} -> {value}")
