Good idea for a PR! resize_and_crop_images.py and summarize.py have problems with print expressions as well. There are some inconsistencies in parse_log.py, which has both print xxx and print(xxx) syntax. I did not check for other issues as I'm not very familiar with Python 3.5 myself.

Would you be able to fix bugs and provide 3.5-compatible versions of the scripts? I would gladly accept such PR.
I would recommend leaving existing (2.7-compatible) scripts intact - people might load them in their own programs, so renaming or significantly modifying them might break their setups.

@Noiredd May i ask what are the steps for the PR <- Should i directly modify the code or other methods?
