Dictionary_Methods.py

# I learn these objects method in JavaScript, but i might as well apply it in python
# These are the 3 functions we will use:
# values() = Similar to Object.values() in JavaScript
# keys() = Similar to Object.keys() in JavaScript
# items() = Similar to Object.entries() in JavaScript
# and some advanced object methods

Name_Age = {
    "jake":15,
    "john":16
}

# To access the age of jake:
print(f"Jake's age is {Name_Age["jake"]}")

# To access the age of john:
print(f"John's age is {Name_Age["john"]}")

# To add value, simply add using equal sign
# This will also work on update, if you want to change the existing value of the dictionary
Name_Age["bob"] = 20
print(f"Bob's age is {Name_Age["bob"]}")
Name_Age["john"] = 21
print(f"John's new age is {Name_Age["john"]}")
