# A Python dictionary is a collection of key-value pairs. 
#   Each key is connected to a value, and you can use a key to access the value associated with it.
#   A key’s value can be a number, a string, a list, or even another dictionary.
#   In Python, a dictionary is wrapped in braces, {}, with 
#   a series of key-value pairs inside the braces, as shown in the following example:
dictionary = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
print("Starting dictionary:\n", dictionary)

# add a key-value pair to a dictionary
dictionary['key4'] = 'value4' 
print("\nadd a key-value pair to a dictionary:\n", dictionary) 

# access a value in a dictionary
print("\naccess a value in a dictionary:\n", dictionary['key1'])
print("\naccess a value in a dictionary using get method:\n", dictionary.get('key1'))

# update a value in a dictionary
dictionary['key1'] = 1 
print("\nupdate a value in a dictionary:\n", dictionary) 

# remove a key-value pair from a dictionary
del dictionary['key2'] 
print("\nremove a key-value pair from a dictionary:\n", dictionary) 
dictionary.pop('key3') 
print("\nremove a key-value pair from a dictionary using pop method:\n", dictionary)
