# This automatically creates a new element where

# Append to Dictionary in Python

# Let's say we had the following dictionary:

languages = {'#1': "Python", "#2": "Javascript", "#3": "HTML"}

# There are two ways to add a key-and-value set to this dictionary

# Number 1: By .update() method

languages.update({"#4": "C#"}) # Adds a #4 key-and-value set

#--------------------------------------------

# Number 2: The define-key method

# This is the easier one

languages['#4'] = 'C#'

# ^^ Just updates a key of #4 to C#, or adds it in this case

# Let's create a dictionary, the functional way 
  
# Create your dictionary class 
class my_dictionary(dict): 
  
    # __init__ function 
    def __init__(self): 
        self = dict() 
          
    # Function to add key:value 
    def add(self, key, value): 
        self[key] = value 
  
# Main Function 
dict_obj = my_dictionary() 
  
dict_obj.add(1, 'Geeks') 
dict_obj.add(2, 'forGeeks') 
  
print(dict_obj)
