Print a Bitarray array into a document.dat

Question

I am trying to print in a documents bits 1 an 0 and I have the next code

from bitarray import bitarray

a = bitarray()
a.append(True)
a.append(False)
a.append(True)

print(a)

f = file("bits.dat","wb")
f.write(a)
f.close()

It seems that it works but when I open the document bit.dat appears an error that I do not known how to solve.

Any ideas?

I seems you are just opening the file in a wrong way – you are opening it as if it contained text, which is not the case. The viewer tries to interpret the data as UTF-8-encoded text, but the byte you've made is not valid UTF-8. Just try to view the file as binary data.

Do you know how con I change the view mode to binary? – victor Oct 25 '15 at 10:24
@victor: That's application specific. Maybe the select at the bottom that says “Plain Text” could be changed to something like “Binary”. – user87690 Oct 25 '15 at 10:30
I have already proved some of the diferent options and they did not work – victor Oct 25 '15 at 10:41
@victor: You can also display the contents of the file interactively in Python. – user87690 Oct 25 '15 at 10:45

You may need a hex editor to open that file, for example:

GHex - a hex editor for GNOME
Bless Hex Editor

When I view the (bits.dat) file in a hex editor I get the following.

00000000:  b1                                                           :.
