Upload Binary File from Memory

This example demonstrates how to upload a binary file from memory. It uploads the file to a subdirectory of our choosing. Chilkat2-Python

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example uses a previously obtained access token having permission for the 
# Google Drive scope.

# The 1st part is JSON with information about the file.

# To place the file in a folder, we must add a parents[] array to the JSON
# and add the folder ID.  
# In a previous example (see Build Local Metadata Cache
# we built a local cache to make it easy to lookup file IDs given a file path.
# Let's find the file ID for the folder "testFolder/abc/123"
