A thread to assist in the conversion of python 2 to python 3. Anything you come across that you have found a conversion for can be placed in this thread. examples

python 2 : 
print x 
Python 3:
print( x )

python2 
wx.SystemSettings_GetFont(wx.SYS_DEFAULT_GUI_FONT)
python3:
wx.SystemSettings().GetFont(wx.SYS_DEFAULT_GUI_FONT)

python2:
outfile.write( "[advanced]" + "\n")
python3:
outfile.write( bytes("[advanced]" + "\n"), encoding = 'utf8' )

The standard Python way works fine for file writing:

with open("test.txt", "w") as fh:
    for idx in range(10):
        print(f"Line {idx}: Test", file=fh)  # The 'f' prefix means: format, Py3 only.

with open("test2.txt", "w") as fh:
    for idx in range(10):
        fh.write(f"Line {idx}: Test\n")

Thanks Dizzi - useful info :)

If you saved objects with pickel in older poser versions and want to load them in Poser 12 you will have to do something like that:

with open(filename, "r") as fd:
 lines = [line.rstrip("rn") for line in fd.readlines()]
 result = pickle.loads(bytes("n".join(lines), encoding='Latin 1'))

Can we make this thread a sticky/pin/whatever-you-call-it ?
