Pre-data analysis

Python version python 2 or Python 3

• Python 2.x is an earlier version, Python 3.x is the current version
• Python 2.7 (final version of 2.x) rarely has a big update since its release in 2010
• Python 2.x has more tool libraries than python3.x
• Most Linux systems installed by default are still Python 2.x
• Version selection depends on the problem to be resolved

Recommended case for Python 2.x:

• The deployment environment is not controllable and Python version cannot be selected by itself
• Some tool libraries are not yet available to support Python 3.x.
• If you choose to use Python 3.x, you need to decide which tool library to use to support the new version.

Note: This course will use the Python 3.x version
