i have a string of bytes like temp="101110110011" i want to write this string in binary file. i did it by :

with open("some binary file.bin", "wb") as f:
    bytes = str.encode (some string)
    f.write(bytes)

but because I use it for huffman encoding it will make my bin file size larger

how to save above string as binary directly in python 3 my string range is more than 32 bits

What problem are you seeking help with exactly? – Jon Clements Nov 20 '16 at 12:12

Do you expect `"10111011"` to occupy 1 byte or 8 in the file? – John Zwinck Nov 20 '16 at 12:12
`"101110110011"` looks suspiciously like a string of *bits*, not *bytes*. Are missing a conversion step? – MisterMiyagi Nov 20 '16 at 12:17
yes I have string of bits. now how I write this string in binary file. – REZA TALEBI Nov 20 '16 at 14:07
from array import * `bin_array = array('B') bin_array.append(int('011',2)) bin_array.append(int('010',2)) bin_array.append(int('110',2)) f = file('binary.mydata','wb') bin_array.tofile(f) f.close()` – REZA TALEBI Nov 20 '16 at 14:15
i found above code from [link](http://stackoverflow.com/questions/16887493/write-a-binary-integer-or-string-to-a-file-in-python) – REZA TALEBI Nov 20 '16 at 14:16
but does not work on python 3.x – REZA TALEBI Nov 20 '16 at 14:18
