Change suggestion to Python code comments

[MikeB2019x]

Currently the code for python here does not indicate what int values are appropriate for entry. Suggest the description for the mode parameter be altered from:

# Compress a byte string.
def compress(string, mode=MODE_GENERIC, quality=11, lgwin=22, lgblock=0):
    """Compress a byte string.

    Args:
      string (bytes): The input data.
      mode (int, optional): The compression mode can be MODE_GENERIC (default),
        MODE_TEXT (for UTF-8 format text input) or MODE_FONT (for WOFF 2.0).

to:

# Compress a byte string.
def compress(string, mode=0, quality=11, lgwin=22, lgblock=0):
    """Compress a byte string.

    Args:
      string (bytes): The input data.
      mode (int, optional): The compression mode can be of value 0 for  generic input (MODE_GENERIC),
      of value 1 for UTF-8 format text input (MODE_TEXT ) or of value 2 for WOFF 2.0 font data (MODE_FONT).
      Default is 0.

The integer values are drawn from the commentary in the `
