Problem scenario
You want to use a sorted dictionary in Python. What do you do?

Solution
Create a sorted list based on the dictionary’s keys. Use the list as keys to summon the dictionary’s values.

contint_dict = {}
contint_dict[”a_test”] = “123”
contint_dict[”b_test”] = “456”
contint_dict[”c_test”] = “789”
sorted_dict_list = sort1ed(contint_dict.items()) # sorted_dict_list is a list, not a dictionary.
list_of_keys = sorted(contint_dict.keys())

for key_pair in sorted_dict_list:
print(key_pair)

print(“”)
print(“Above are key-pairs. …

Problem scenario
You want to create a dictionary of dictionaries in Python. You want to use them. What do you do?

Solution
Here is an example/illustration:

contint_dict = {}
contint_dict[”a_test”] = “123”
contint_dict[”b_test”] = “456”
contint_dict[”c_test”] = “789”

color_animal_dict = {}
color_animal_dict[”blue”] = “dog”
color_animal_dict[”orange”] = “cat”
color_animal_dict[”green”] = “goat”

days_dict = {}
days_dict[”Tuesday”] = “midnight”
days_dict[”Wednesday”] = “noon”
days_dict[”Thursday”] = “evening”

big_dictionary = {}
big_dictionary[”dict_1″] = contint_dict
big_dictionary[”dict_2″] = color_animal_dict
big_dictionary[”dict_3″] = days_dict

print(big_dictionary[”dict_1″][”b_test”])
print(big_dictionary[”dict_2″][”green”])
print(big_dictionary[”dict_3″][”Wednesday”])

super_dictionary = {}
super_dictionary[”top_of_nested”] = big_dictionary
print(super_dictionary[”top_of_nested”][”dict_3″][”Wednesday”])
