Simple python script to upload file to Dropbox.

SFileUploader.py

#!python3.5

# Prerequisites :
# 1.SetUp dropbox sdk to be able to use Dropbox Api's
# $ sudo pip install dropbox
# By default python dropbox sdk is based upon the python 3.5
#
# 2. Create an App on dropbox console (https://www.dropbox.com/developers/apps) which will be used and validated to do
# the file upload and restore using dropbox api. Mostly you need an access token to connect to Dropbox before actual file/folder operations.
#
# 3. Once done with code, run the script by following command
# $ python SFileUploader.py // if python3.5 is default


import sys
import dropbox

from dropbox.files import WriteMode
from dropbox.exceptions import ApiError, AuthError

# Access token
TOKEN = '<Generated after after App creation in step 2 in Prerequisites>'

LOCALFILE = '<Path to the file to be uploaded>'
BACKUPPATH = '/<desitination filename>' # Keep the forward slash before destination filename


# Uploads contents of LOCALFILE to Dropbox
def backup():
    with open(LOCALFILE, 'rb') as f:
        # We use WriteMode=overwrite to make sure that the settings in the file
        # are changed on upload
        print("Uploading " + LOCALFILE + " to Dropbox as " + BACKUPPATH + "...")
        try:
            dbx.files_upload(f.read(), BACKUPPATH, mode=WriteMode('overwrite'))
        except ApiError as err:
            # This checks for the specific error where a user doesn't have enough Dropbox space quota to upload this file
            if (err.error.is_path() and
                    err.error.get_path().error.is_insufficient_space()):
                sys.exit("ERROR: Cannot back up; insufficient space.")
            elif err.user_message_text:
                print(err.user_message_text)
                sys.exit()
            else:
                print(err)
                sys.exit()


# Adding few functions to check file details
def checkFileDetails():
    print("Checking file details")

    for entry in dbx.files_list_folder('').entries:
        print("File list is : ")
        print(entry.name)


# Run this script independently
if __name__ == '__main__':
    # Check for an access token
    if (len(TOKEN) == 0):
        sys.exit("ERROR: Looks like you didn't add your access token. Open up backup-and-restore-example.py in a text editor and paste in your token in line 14.")

    # Create an instance of a Dropbox class, which can make requests to the API.
    print("Creating a Dropbox object...")
    dbx = dropbox.Dropbox(TOKEN)

    # Check that the access token is valid
    try:
        dbx.users_get_current_account()
    except AuthError as err:
        sys.exit(
            "ERROR: Invalid access token; try re-generating an access token from the app console on the web.")

    try:
        checkFileDetails()
    except Error as err:
        sys.exit("Error while checking file details")

    print("Creating backup...")
    # Create a backup of the current settings file
    backup()

    print("Done!")

tested and running with python 3.6.2, thanks!

Also works perfectly with Python 3.5.2

Everything seems to run, except it is having trouble finding the local file:
Traceback (most recent call last):

backup()

with open(LOCALFILE, 'rb') as f:

Windows 10, python 3.6

Never mine.... I figured out that the "" should be "/"

Exception has occurred: AttributeError
'UploadWriteFailed' object has no attribute 'error'
File "/Users/Yen/AI應用/dropbox-sdk-python-master/dropboxtest.py", line 45, in backup
sys.exit()

This is so easy to understand, thank you for writing this!

This is great. I confirmed this short script works with Python 3.10 in 2023.
