Python - How to open n different json files and just append. once

What I am trying to do is that I want be able to print out n times pending on how many json files I have in the folder while it prints out all these data for each json BUT it should only add to old_list once.

My code I have coded is following:

old_list = ['Hello', 'How', 'Are', 'You']
new_list = ['Im', 'Fine', 'Today', 'You']

    while True:

        if new_list not in old_list:
            directory = os.fsencode('./slack')
            for counters, file in enumerate(os.listdir(directory)):
                filename = os.fsdecode(file)
                if filename.endswith(".json"):
                    with open('./slack/' + filename) as slackAttachment:
                        data = json.loads(slackAttachment.read())

                        data_list = []


                        data["attachments"][0]["footer"] = str(
                            data["attachments"][0]["footer"] + ' | ' + datetime.now().strftime(
                                '%Y-%m-%d [%H:%M:%S.%f')[:-3] + "]")

                        # -------------------------------------------------------------------------

                        print(data)

                        old_list.append(new_list)

The problem right now I am having is that it is adding to the list n times depending on how many json files I have and what I want to make is that it should print out all the json but only add to the list once instead of n times.

My question in that case is: How can I be able to add the list only once but still be able to print out all these jsons?

The problem is your while True which causes your code print out non stop. Moreover, if new_list not in old_list: is not a right way to compare two lists:

old_list = ['Hello', 'How', 'Are', 'You']
new_list = ['Im', 'Fine', 'Today', 'You']
data_list = []
directory = os.fsencode('./slack')
for newLst in new_list:
  if newLst in old_list:
    for counters, file in enumerate(os.listdir(directory)):
        filename = os.fsdecode(file)
        if filename.endswith(".json"):
                    with open('./slack/' + filename) as slackAttachment:
                        data = json.loads(slackAttachment.read())          
                        data["attachments"][0]["footer"] = str(
                            data["attachments"][0]["footer"] + ' | ' + datetime.now().strftime(
                                '%Y-%m-%d [%H:%M:%S.%f')[:-3] + "]")

                         print(data)

     data_list.append(newLst) # make sure to what you're ganna append

Note that I'm assuming the rest of your code is working well.
