interpret a string made of 0 and 1 as a binary sequence?

Question

Using python, I want to convert/interpret a string made of 0 and 1 as if it was binary.

Assume I have a string that looks like this:

>>>str = "010010000110010101101100011011000110111100100000010101110110111101110010011011000110010000100001"

I would like a function (or whatever) to retrieve Hello World!.

@CoryKramer, isn't that the wrong dupe? OP wants it converted to ASCII, which is what the dupe I linked does. — Morgan Thrapp, Oct 14 '15 at 16:17
Your question isn't clear at all. You're missing the connection between interpreting as binary and "retrieving "Hello World!". — juanchopanza, Oct 14 '15 at 16:17

This should do what you want. for i in xrange(0, len(b), 8) gets the bits for each character separately, and chr(int(b[i:i+8], 2)) converts the ASCII 1s and 0s to the character code.

>>> b = "010010000110010101101100011011000110111100100000010101110110111101110010011011000110010000100001"
>>> print "".join(chr(int(b[i:i+8], 2)) for i in xrange(0, len(b), 8))
Hello World!

from itertools import izip

str = "010010000110010101101100011011000110111100100000010101110110111101110010011011000110010000100001"
print ''.join(chr(int(''.join(b8), 2)) for b8 in izip(*[iter(str)]*8))

Output:

Hello World!
