This means that you need to include parenthesis now. print("Hello World") http://docs.python.org/3.0/whatsnew/3.0.html#print-is-a-function share|improve this answer edited Aug 9 '15 at 23:35 Mateusz Grzejek 5,67321336 answered May 5 '09 at 21:21 Unknown 29.6k15104162 add a comment| up vote 40 down vote It looks like you're usin

Pretty much nobody is using 9-year-old Python 2.5 or earlier nowadays, and Python 3's popularity is growing relative to 2.7. It would be helpful for future visitors if you were to accept ilya n's answer instead, since it covers all Python versions; could you please do so? –Mark Amery Nov 4 '15 at 11:50 add a comment| 5 Answers 5 active oldest votes up vote 191 down vote accepted except Exception,e: print str(e) share|improve this answer answered Sep 27 '09 at 12:19 jldupont 41.9k32140258 11 the str() part is redundant -- print e is exactly the same thing as print str(e) [[i.e., print does its own stringification]]. –Alex Martelli Sep 27 '09 at 16:40 4 @alex: doesn't it depends on the subclass (if any) of the exception thrown?

wondering with which version of Python they should start. My answer to this question is usually something along the lines “just go with the version your favorite tutorial was written in, and check out the differences later on.” But what if you are starting a new project and have the choice to pick? I would say there is currently no “right” or “wrong” as long as both Python 2.7.x and Python 3.x support the libraries that you are planning to use. However, it is worthwhile to have a look at the major differences between those two most popular versions of Python to avoid common pitfalls when writing the code for either one of them, or if you are planning to port your project. Sections Sections The __future__ module The print function Python 2 Python 3 Integer division Python 2 Python 3 Unicode Python 2 Python 3 xrange Python 2 Python 3 The __contains__ method for range objects in Python 3 Note about the speed differences in Python 2 and 3 Raising exceptions Python 2 Python 3 Handling exceptions Python 2 Python 3 The next() function and .next() method Python 2 Python 3 For-loop variables and the global namespace leak Python 2 Python 3 Comparing unorderable types Python 2 Python 3 Parsing user inputs via input() Python 2 Python 3 Returning iterable objects instead of lists Python 2 Python 3 Banker’s Rounding Python 2 Python 3 More articles about Python 2 and Python 3 The __future__ module Python 3.x introduced some Python 2-incompatible keywords and features that can be imported via the in-built __future__ module in Python 2. It is recommended to use __future__ imports it if you are planning Python 3.x support for your code. For example, if we want Python 3.x’s integer division behavior in Python 2, we can import it via from __future__ import division More features that can be imported from the __future__ module are listed in the table below: feature optional in mandatory in effect nested_scopes 2.1.0b1 2.2
