python + byte array

[Ruslan]

Hi, everybody.

I use win32com package to call WinHTTP COM methods.
One of them is 'Send'. I can pass string parameter to 'Send' method from
python - it's OK, but to send binary data i need somehow pass in 'Send'
method data of _byte array_ type(Visual Basic type). Does anybody know
how to mimic that 'byte array' type of Visual Basic in Python (i need to
pass big chunks of binary data in 'Send')?
I tried struct.pack, but that doesn't seem to be an option.

Thanks in advance.
Your help is very appreciated.

Best regards,
Ruslan
