buffer_info error

[ashtonn]

Hello,

buffer_info is giving the following error:

AttributeError: 'str' object has not attribute 'buffer_info'

Here's the code snippet...

dest = 'FFFFFFFFFFFF'
src = '0123FFFFFFFF'

data = array('B', '\0' * 256)
data1 = ''.join([dest, src]
print data1print data.buffer_info()[0]... works

print data1.buffer_info()[0]....error

This output is a string and hence i believe i get the above error. Any
ideas?


Thanks,
-Ashton

Yes, you are entirely correct. (Integers don't have "buffer_info"
attributes either, and for that matter strings don't have an attribute
called "fribble_frabble", in case you were thinking of trying that. ;-)

(That's a facetious reply, yes, because you gave no indication what you
were trying to accomplish. It's really hard to tell what you expected
versus what you got, and why you got that is completely obvious to all
of us, who can't read your mind.)

i am filling in a packet with source and destination address and using
the buffer_info call to pass on the address to an underlying low level
call.

The src and dest are strings, but buffer_info expects an array. How do
i deal with this?
