HELP: String of Zero's and One's to binary byte

[heiner55]

Your code is OK except "B" for "!H".
And you need an editor which is able to open
the file as UTF-16 with BOM.

#!/usr/bin/python3
import struct

lst = ('11111111', '11111110',
       '01101000', '00000000',
       '01101001', '00000000',
       '00001101', '00000000',
       '00001010', '00000000')

def writer(stuff):
   blob = struct.pack('B', int(stuff, 2))
   with open('test.txt', "a+b") as file:
       file.write(blob)

for strings in lst:
   writer(strings)
#done

---

Or without struct:

#!/usr/bin/python3
lst = ('11111111', '11111110',
       '01101000', '00000000',
       '01101001', '00000000',
       '00001101', '00000000',
       '00001010', '00000000')

def writer(stuff):
   blob = int(stuff, 2).to_bytes(1, byteorder='big')
   with open('test.txt', "a+b") as file:
       file.write(blob)

for strings in lst:
   writer(strings)
#done
