how to init binary buffer in python

so, I read from DB binary field i.e. 'field1' to var Buf1, and then do so开发者_如何转开发mething like:

unpack_from('I', Buf1, 0)

so, all is ok. but question is how can I ini Buf1 without going to DB? I can get value from DB manually and init my var statically, but how? in DB field 'field1' I see something like '0x7B0500000100000064000000B80100006'. and how can I init valid binary buffer from it?

Just use pack or pack_into it's the python's opposite of unpack_from.

But you should elaborate on your question and give more sample code. The value you say you see from field is too large to read it into an integer. I wonder if you get the complete value.
