[FIXED] how to plot each key of a dictionary in python?

Issue

I have a dic of list type. like this :

{'key': '3d animator',
  'Results': [{'freelance artist': 1}, {'3d artist': 2}]},
 {'key': '3d artist',
  'Results': [{'sous chef': 1},
   {'3d animator': 2},
   {'art director': 1},
   {'artist': 1}]},
 {'key': '3d designer',
  'Results': [{'network administrator': 1}, {'None': 1}]}

can I plot a graph for each key, and show by hist the frequency of the values ('Results) ? for example for key= 3d animator, a hist chart where in the horizontal axis I have 'freelance artist' and 3d artist and in the vertical axis their frequency 1 and 2?

Solution

First suggestion is to reformat your data:

my_list = [{'key': '3d animator',
  'Results': [{'freelance artist': 1}, {'3d artist': 2}]},
 {'key': '3d artist',
  'Results': [{'sous chef': 1},
   {'3d animator': 2},
   {'art director': 1},
   {'artist': 1}]},
 {'key': '3d designer',
  'Results': [{'network administrator': 1}, {'None': 1}]}]

Assuming each key in subdict lists is unique:

final_dict = {elem["key"]:{k: v for d in elem["Results"] for k, v in d.items()} for elem in my_list}

Then plot each value (dict) of the outer dict (dataset):

import matplotlib.pyplot as plt
for k,v in final_dict.items():
    plt.figure()
    plt.title(k)
    plt.bar(list(v.keys()), v.values())
plt.show()

This plots a graph for each key of the dataset (if that's your need).
