The append method should be used to add a new item to a dictionary. code example

Example 1: dictionary in python does not support append operation

dict_append = {"1" : "Python", "2" : "Java"}
dict_append.update({"3":"C++"})  # append doesn't supported in dict 
								 # instead , use update in dict
print(dict_append)
# output : {'1': 'Python', '2': 'Java', '3': 'C++'}

Example 2: append to dictionary python

# 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
