Uploading, downloading files and equations in text

[leungi]

While at it, why add .zip to the list, so one may pack anything into download

Courtesy of a SO post:

zip_path = "test.zip"
my_zipfile = zipfile.ZipFile(zip_path, mode='w', compression=zipfile.ZIP_DEFLATED)

# Write to zip file
my_zipfile.write(excel_path)

my_zipfile.close()

with open(zip_path, "rb") as f:
    bytes = f.read()
    b64 = base64.b64encode(bytes).decode()

Similar as before, once we get the decoded b64 data, the remaining implementation is covered in @Marc example.
