[FIXED] How to translate a stream of '0' and '1' to characters?

Issue

I'm trying to translate a stream of 0, 1 to characters, without using other libraries,

for example 'Hello World':

0100100001000101010011000100110001001111001000000101011101001111010100100100110001000100

I found something like this:

def BinaryToString(binary):
    bingen = (binary[i:i+7] for i in range(0, len(binary), 7))
    return ''.join(chr(eval('0b'+n)) for n in bingen)

but when I'm trying to translate, this is the answer:

>>> BinaryToString("0100100001000101010011000100110001001111001000000101011101001111010100100100110001000100")
"$\x11)Db<@W'TID\x04"
>>> 

Solution

That function is taking 7 binary digits at a time and converting them to a character. Change it to convert 8 digits at a time.

def BinaryToString(binary):
    bingen = (binary[i:i+8] for i in range(0, len(binary), 8))
    return ''.join(chr(eval('0b'+n)) for n in bingen)

This all depends on how your original text is encoded to begin with, but it works with the example you provided. (ASCII was originally defined using 7 bits. The extended ASCII table uses 8.)
