IBM Personality Insights Syntax Errors

Question

I'm trying to learn the basic of how the IBM Watson Personality Insights API works before it shuts down at the end of this year. I have a basic text file that I want analyzed, but I'm having trouble getting the code to run properly. I have been trying to follow along on the official sits instructions, but I'm stuck. What am I doing wrong? (I have blotted out my key in the below code).

from ibm_watson import PersonalityInsightsV3
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator

authenticator = IAMAuthenticator('BlottedOutKey')
personality_insights = PersonalityInsightsV3(
    version='2017-10-13',
    authenticator=authenticator
)

personality_insights.set_service_url('https://api.us-west.personality-insights.watson.cloud.ibm.com')
with open(join(C:\Users\AWaywardShepherd\Documents\Data Science Projects\TwitterScraper-master\TwitterScraper-master\snscrape\python-wrapper\Folder\File.txt), './profile.json')) as profile_json:
    profile = personality_insights.profile(
        profile_json.read(),
        content_type='text/plain',
        consumption_preferences=True,
        raw_scores=True)
    .get_result()
print(json.dumps(profile, indent=2))

I keep getting the following nondescript syntax error:

  File "<ipython-input-1-1c7761f3f3ea>", line 11
    with open(join(C:\Users\AWaywardShepherd\Documents\Data Science Projects\TwitterScraper-master\TwitterScraper-master\snscrape\python-wrapper\Folder\File.txt), './profile.json')) as profile_json:
                    ^ SyntaxError: invalid syntax

There is so much wrong with that open line.

• join is expecting an itterable which it joins into a single string.
• In Python, strings become strings by enclosing them with quotes (paths are just strings !)
• You are only passing one value into join, which makes it redundant.
• The second parameter for open should be a mode, and not a file name.
• It looks like you are trying to append a directory with a file name, but for that to work the directory shouldn't end with a filename.
• The brackets don't match - You have 2 opening brackets and 3 closing brackets.

In Python you use join to join strings to gather. Normally this would be a path and a filename. Getting the path from the current working directory and joining it with a path.

import os

file = os.path.join(os.getcwd(), 'profile.json')

In your code you are only passing in one string, so there is no need to use join.

Using open you pass in the filename and the mode. The mode would be something like 'r' indicating read mode. So the code with the join becomes.

import os

with open(os.path.join(os.getcwd(), 'profile.json'), 'r') as profile_json:
