visualize_1541_blocks.py seems to be python 2?

[Rhialto]

It seems that visualize_1541_blocks.py is not python3 but python2 ?

visualize_1541$ python3 visualize_1541_blocks.py "somefile.g64" 1b.png
  File ".../visualize_1541/visualize_1541_blocks.py", line 108
    print "track {}, offset {}, size {}, speed {}".format(trackno, offset, len, speed)
