Convert Nested Dictionary to CSV Table

Question

I\'m going through a data mining tutorial and I\'m using the following dictionary.

users = {
    \"Angelica\": {
        \"Blues Traveler\": 3.5, 
        \"         


        

Answer 1

Try this

import csv
# Create header line
a = ["Album/Track"] + users.keys()

# Create unique keys.
x = list(set([y for z in users.values() for y in z.keys()]))

# Create rows
rows = [a]+[[q]+[users[p].get(q, '-') for p in a[1:]] for q in x]

with open('my.csv', 'wb') as csvfile:
    writer = csv.writer(csvfile)
    for row in rows:
        writer.write(row)
