User input to upload files to Google Drive via Google Colab Notebook

I'm designing a tool that is going to be used by lots of non-coders, and the easiest way to have it accessible to everyone is through a notebook on Google Colab. Within the notebook, I'd like to be able to prompt for user input, e.g. "upload a video folder" and have this be uploaded to a specific folder within google drive. That way, the notebook can access this folder throughout the program without users having to manually specify any filepaths. Does anyone know of a way to do this?

I have read a similar post which suggested:

from google.colab import files

files.upload()

but this only uploads to the notebook's limited temporary storage and not the user's Google Drive. Folders being uploaded may be around 1 to 2gb (containing dozens of .avi videos).

I don't know if this resolves all your problems but Google Colab has special module to access Google Drive

from google.colab import drive

drive.mount('/content/drive')

and it will display drive/MyDrive in Files on right side.

And Google Colab allows to set target folder in upload()

from google.colab import files

files.upload('/content/drive/MyDrive')
#files.upload('drive/MyDrive')

You can access this drive in code

import os

os.listdir('/content/drive/MyDrive')

import pandas

df = pd.read_csv('/content/drive/MyDrive/my_data.csv')

You can use ipython.widgets (like Dropdown or Select) to display list of folders and execute upload with selected folder.

import ipywidgets as widgets
from IPython.display import display

base = '/content/drive/MyDrive'

filenames = os.listdir(base)
folders = [name for name in filenames if os.path.isdir(os.path.join(base, name))]

# add base folder on drive as first on list
folders.insert(0, '.')

Dropdown_ = widgets.Dropdown(
    options=folders,
    description='Select folder',
)

output = widgets.Output()

def on_change(change):
    name = change['new']
    fullname = os.path.join(base, name)
    print('name:', name)
    print('full:', fullname)
    files.upload(fullname)

Dropdown_.observe(on_change, names='value')
display(Dropdown_)

(based on code from answer: python - Using google colab forms input as dropdown, can I put the read file and add on the total list? - Stack Overflow)
