Problems with python example

Traceback (most recent call last):

ftdi.write_data(ftdic, chr(0xff), 1)
TypeError: write_data() takes exactly 2 arguments (3 given)

After removing the last argument, i.e., deleting " , 1", it seems to
work fine. Maybe there is a change between libftdi1 version 1.2 and 1.3.

The issue is still in latest git.

1) simple.py works fine
(playusb) c:\work\libftdi\libftdi\python\examples>python simple.py
[FTDI version] major: 1, minor: 4, micro: 0, version_str: 1.4,
snapshot_str: v1.4-12-g91dbb65
ftdi.usb_open(): 0
ftdi.set_baudrate(): 0

2) cbus.py throws invalid syntax error
(playusb) c:\work\libftdi\libftdi\python\examples>python cbus.py
File "cbus.py", line 93
print 'manufacturer="%s" description="%s" serial="%s"' %

3) complete.py has the same problem as before.
(playusb) c:\work\libftdi\libftdi\python\examples>python complete.py

Traceback (most recent call last):
File "complete.py", line 63, in <module>
ftdi.write_data(ftdic, chr(0xff), 1)
TypeError: write_data() takes 2 positional arguments but 3 were given

4) After removing the last argument, i.e., deleting " , 1", it seems to
work a bit further but complete.py still does not work.

(playusb) c:\work\libftdi\libftdi\python\examples>python complete.py

turning everything on
TypeError: expected bytes, str found

The above exception was the direct cause of the following exception:

ftdi.write_data(ftdic, chr(0xff))
File "C:\work\pyenv64\playusb\lib\site-packages\ftdi1.py", line 342,
