Writing to Google Sheets

Reading is great, but writing data back to the sheet is where the magic happens. You can use Python to automate reports, update dashboards, or save user inputs.

Here is how you update a specific cell:

# Update cell A1
worksheet.update('A1', 'Updated by Python!')

Or, if you want to add a new row to the bottom (like a log entry):

new_user = ["Charlie", "35", "London"]
worksheet.append_row(new_user)

Now, if you look at your actual Google Sheet in the browser, you'll see "Charlie" appear instantly! It's like having a ghost typer working for you.
