Hi,
I read a bmp file (binary file) and I want to extract an integer value
from it (size value).
The whole binary file is read inside a list all_bmp_file.
I can read the size value with the following code:
for r in all_bmp_file[2:5]:
n = struct.unpack('B',r)#B for unsigned char
print n
As your 'for' loop shows, the number of items in the slice [2:5] is only
3, not 4.
Maybe you want the slice [2:6] instead.
x = xx\xb6/\0\0
struct.unpack('i', x[2:6])
(12214,)

Hi Jeff,
You was right, my problem was coming from the number of items that I
gave to the unpack method.
I was thinking,like an array in C, that slice [2:5] will give 4 items and not 3.
Thanks a lot for your help.
