# DROPBOX IMPORT FOR PYTHONISTA 3
#
# SETUP INSTRUCTIONS:
# 
# 1. Go to https://www.dropbox.com/developers/apps (log in if necessary)
# 2. Select "Create App"
# 3. Configure your app:
#    * Select "Dropbox API"
#    * Choose whichever access level you prefer ("Full Dropbox" or "App Folder")
#    * Enter the app name you wish to use for this script. It must be unique across all Dropbox apps. 
#    * Select the account to associate with this app. 
#    * Agree to the terms and conditions and click "Create app"
# 4. On the newly-created app's summary page, click the "Generate"
#    button under "Generated access token"
# 5. Copy the generated token and paste it below (replace "YOUR_TOKEN_HERE").
# 6. (optional) Open the "wrench" (actions) menu in Pythonista and add
#    this script, so you can run it from everywhere in Pythonista.

# Notes:
# All selected files are downloaded into the root folder of the Pythonista
# script library. If a file with the same name already exists, a numeric
# suffix is appended automatically.

Thanks for solving the Pythonista3 external file transfer problem on my iPhone 7. DropBox turned out to be a great middle man for the job. I used iFiles 2 to migrate dropboxImport.py over to the iPhone 7. From there I had to import it to a Notes file. After that I was able to copy and paste it into a Pythonista3 script file. The script ran flawlessly. It works stellar after you get the DropBox App Token set up properly. Thanks again. Now that I can call dropboxImport.py within Pythonista3, all I need is DropBox to import Python scripts! Fantastic!

Thanks for this. I get the same "Could not load folder please check if you entered the access token correctly" error as facebawx.

I bought my .py scripts over Google Drive as text and renamed them. That worked fine.

What format does Pythonista 3 expect for text files? I moved an ANSI file from Notepad to Pythonista, but it takes about 20 sec to display in the the Pythonista editor (perhaps it's converting formats) and when I try a readline, it says "UnicodeDecodeError,
ascii codec can't decode byte 0xb7 in 15..." If I paste the first few lines of the text into a new file window, it works, but the file is too long (~1.5 MB) to paste the whole thing from a scratchpad.

Hi All,

I am new to the world of coding so this may be a dumb question.

I keep getting the attribute error: 'function' object has no attribute 'get'
Does anyone know how to fix this?
