How can I save a list of dictionaries to a file?

Question

I have a list of dictionaries. Occasionally, I want to change and save one of these dictionaries so that the new message is utilized if the script is restarted. Right now, I make that change by modifying the script and rerunning it. I'd like to pull this out of the script and put the list of dictionaries into a configuration file of some kind.

I've found answers on how to write a list to a file, but this assumes that it is a flat list. How can I do it with a list of dictionaries?

My list looks like this:

logic_steps = [     {         'pattern': "asdfghjkl",         'message': "This is not possible"     },     {         'pattern': "anotherpatterntomatch",         'message': "The parameter provided application is invalid"     },     {         'pattern': "athirdpatterntomatch",         'message': "Expected value for debugging"     }, ] 

Answer 1

provided that the object only contains objects that JSON can handle (lists, tuples, strings, dicts, numbers, None, True and False), you can dump it as json.dump:

import json with open('outputfile', 'w') as fout:     json.dump(your_list_of_dict, fout) 

Answer 2

if you want each dictionary in one line:

 import json  output_file = open(dest_file, 'w', encoding='utf-8')  for dic in dic_list:     json.dump(dic, output_file)      output_file.write("\n")
