Why doesn't Python come pre-built with required libraries like pandas, numpy etc [closed]

Question

What is the reason packages are distributed separately?

• Why do we have separate 'add-on' packages like pandas, numpy?
• Since these modules seem so important, why are these not part of Python itself?

Are the "single distributions" of Python to come pre-loaded?

• If it's part of design to keep the 'core' separate from additional functionality, still in that case it should at least come 'pre-imported' as soon as you start Python.

• Where can I find such distributions if they exist?

Answer 1

Many of these tools, including core Python, are separately developed and distributed by different team, so it is up to aggregators to curate them and put them into a single distribution. Here are some notable examples:

• The Anaconda distribution from Continuum Analytics
• The Canopy distribution from Enthought
• ActivePython from ActiveState
• PythonXY for scientific programming
• WinPython for Windows
• PyIMSL Studio from Rogue Wave Software
