dict = {"arthur1.jpg": [0.123,0.456,0.864], "arthur2.jpg": [0.124,0.764,0.965]}

in csv file this:

arthur1.jpg 0.123   0.456   0.864 arthur2.jpg 0.124   0.764   0.965

the first column dicts's keys be, , next set of columns in same line values of respective key.

turn each key-value pair row; values list, prepend list list literal containing key:

import csv  open(youcsvfilename, 'rb') csvf:     csvwriter = csv.writer(csvf)         filename, values in dictionary.items():         csvwriter.writerow([filename] + values)
