The code sometimes like Python 2

[IL98]

Hi! The python 3.7 is said in the Readme. But some parts of the code reminds Python2, like prints (e.g. there)

Could you explain why is that? It causes the mistakes at some places (like in notebooks in refer)

We only use the refer repo for data loading in data preprocessing. Other than that our codes are based on python 3.7.
