Using struct.pack

My code looks like this :

import struct

str = "AAAAAAA"
len = len(str)+32

package = struct.pack("!H",len)
print repr(package)

the result is :

"\x00'"

When I use len = len(str) the result is \x00\x07

Why when len is larger than 32,it is not working?

You're misunderstanding the "\x00'" result. It's a mixture of a string hexadecimal character code value and a regular printable ASCII character. If it were displayed purely in hexadecimal character codes, it would be "\x00x\x27".

The \x27 in decimal is the integer 39, which is the result of len(str)+32. It's also the character code of the ' (single quote) character, which is part of what repr() is displaying.
