I have a program that I have been trying to rewrite so it will
run on Python 2.7 and 3.4. It has been a pain to say the least.
Thank $DIETY for aliases. Anyway, I got it all working except
for one thing. The program has an embedded icon. It is displayed
in the window's titlebar. The icon is a 16x16 png that has been
base64 encoded using a Linux utility called memencoder. The code
below works perfectly with Python 2.7. The icon data is complete
for anyone that wants to try to run this code:
encoded_icon = """\
To make this literal a bytes literal, prepend 'b'.
encoded_icon = b'''\

app = Window(root)
root.mainloop()
When I run the program with Python 3.4, I get this error:
Traceback (most recent call last):
File "/usr/lib/python3.4/base64.py", line 519, in _input_type_check
m = memoryview(s)
TypeError: memoryview: str object does not have the buffer interface
bytes do have the buffer interface, so I expect that using bytes instead
of str will work.
