>>> struct.pack("i", 119) 
b'w\x00\x00\x00'

"w" in a binary value?

>>> struct.pack("I", 116) 
b't\x00\x00\x00'

"t" in a binary value?

The behaviour is correct. You have tripped over the ASCII representation of bytes. In ASCII, 119 (or in hex, 0x77) is displayed as 'w'.

>>> b'\x77\x00\x00\x00'
b'w\x00\x00\x00'
