# Writing a dictionary in this form (single or multiple lines)
# allows keys to be either an integer or a string
dictionary = {
    1: 'value 1',
    2: 'value 2',
    3: 'value 3',
    }

print(dictionary)
# {'key 1': 'value 1', 'key 2': 'value 2', 'key 3': 'value 3'}
print(dictionary[1])
# value 1

dictionary = {
    'key 1': 'value 1',
    'key 2': 'value 2',
    'key 3': 'value 3',
    }

print(dictionary)
# {'key 1': 'value 1', 'key 2': 'value 2', 'key 3': 'value 3'}
print(dictionary['key 2'])
# value 2

# Alternatively

# When we write dictionary in this form below keys can't
# be integers (as compared to the first example)
# change key1, key2, key3 to 1, 2, 3 respectively
# When keys are integers, 'SyntaxError: keyword can't be
# an expression' is prompted in the console.
# This means keys can only be a set of alphabet or alphanumeric name or
# key which is converted to a string.
dictionary = dict(key1='value 1', key2='value 2', key3='value 3')
print(dictionary)
# {'key1': 'value 1', 'key2': 'value 2', 'key3': 'value 3'}
print(dictionary['key2'])
# value 2

dictionary = dict(name='Osagie', age=25, country='Nigeria')
print(dictionary)
# {'name': 'Osagie', 'age': 25, 'country': 'Nigeria'}
print(dictionary['name'])
# Osagie
