It draws on some things of Python and implements some features not available in Python. There is no direct comparability, but I still think python is easy to use. [Python's purpose is:
Compared with Java and. NET platforms, dynamic languages are lightweight, flexible, and efficient in development, but there are still some gaps in integration cohesion.
