Boto3 with Python3+

Python3+:

Python3 has released new version from core python. They have improved a lot of functionalities in Python3. I will not give a brief explanation of new features, but will try to provide an overview.

Here are the new features added to Python 3+:
a. Dedicated (@) infix operator for matrix multiplication which adds new directory iteration.
b. Function os.scandir() to standard library where an errno.EINTR error code is returned whenever a system calls, that is waiting for I/O, is interrupted by a signal. Previously, Python would raise InterruptedError in such cases. It meant that, while writing a Python application developer would have two choices: Ignore InterruptedError or handle InterruptedError and attempt to restart interrupted system call at every call site.
