====Looping through a dictionary====
The builtin functions <code>.items(), .keys(),</code> and <code>.values()</code> provide you with a lot of flexibility when iterating through dictionaries.

 >>>for i in your_dict.items():
 >>>    print(i)
 ('Bob', 'strawberry')
 ('Cara', 'mint chip')
 ('Dora', 'vanilla')
 ('Alice', 'chocolate')

 >>>for i_key in your_dict.keys():
 >>>    print(i_key + " is a key in this dictionary")
 Bob is a key in this dictionary
 Cara is a key in this dictionary
 Dora is a key in this dictionary
 Alice is a key in this dictionary

 >>>for i_val in your_dict.values():
 >>>    print(i_val + " is a value in this dictionary")
 strawberry is a value in this dictionary
 mint chip is a value in this dictionary
 vanilla is a value in this dictionary
 chocolate is a value in this dictionary

 >>> for i_key, i_val in your_dict.items():
 >>>     print(i_key + " is the key for " + i_val)
 >>>     print(i_val + " is the value for " + i_key)
 >>>     print("\n")
