Python was created in 1980 by Guido Van Rossum. There are differences between Python versions 2.x and 3.x related to compatibility, understandability, maturity, and robustness. Some frameworks like Twisted and gevent have not yet migrated to Python 3.x, while others like NumPy, Django, Flask, CherryPy, Pyramid, PIL, cx_Freeze, and Py2exe have migrated. The document also includes code examples and information about a Python developer.

4. PYTHON 2.X VS 3.X
2.x

Compa7bility

to
understand
Mature

More
robust
MacOS

Could

5. NOT IN PYTHON 3.X YET
Twisted
(for
networking
and
other
applica7ons)
gevent
(like
Twisted,
but
using
micro-­‐threads
rather
than
an
explicitly
asynchronous
style).

6. MIGRATED TO PYTHON 3.X
Numpy
(for
number
crunching)
Django,
Flask
,
CherryPy
and
Pyramid
(for
Web
sites)
PIL
(an
image
processing
module)
cx_Freeze
(for
packaging
applica7ons
with
their
dependencies)
Py2exe
(for
packaging
your
applica7on
for
Windows
users)
