#Note: you do not need to call it dictionary, however
#A dictionary is a collection of key and value pairs that look like this
#The element before the colon( : ) is called a key, and the element after is called a value
#The key can be any data type and the value can be any data type
dictionary = {'key':'treasure', 1:10}
#if I wanted to retrieve the value 'treasure' i would do this
print(dictionary['key'])
#If I wanted all the keys of my dictionary I would use the .keys() method
print(dictionary.keys())
#If I wanted all the values of my dictionary I would use the .values() method
print(dictionary.values())
#If I wanted both the keys and values of my dictionary I would use .items()
print(dictionary.items())Copyright © 2021 Codeinu
