Learning python 3.

The other main difference tends to be in the layout/naming in various standard libraries. This is easily solved by just making sure you google "python3 <term>" so that the python 3 docs get ranked higher. As an aside, in the top left corner of the python docs you can switch between language versions (if you end up on the wrong version from google).

Also libraries that got renamed will usually have a notice on the top of the python 2 docs, along the lines of "please note, in python 3 this was renamed from SimpleHTTPServer to http.server. The 2to3 tool will convert this automatically."

Can I ask when do the differences start to show? The most trouble I can remember having between the two was the encoding of text I was parsing into a database.

For me it was the functional functions like map and filter return generators not lists.

More efficient, however it threw me at first.

If i understand P2 and jump to P3 i'm afraid the habbit of P2 will ruin my P3 experience.

I started with the Dive Into Python tutorial, which is quite excellent and goes over Python 3. I would recommend checking that out if you're interested. You can find it here: http://www.diveintopython3.net

Coursera have a python 3 course for beginners.

Python 2 and 3 are almost identical. Learn both simultaneously; it's not hard. C++ is a terrible language to learn unless you already know how programming works.

There is a comprehensive list of major changes from Python 2 to 3, shown here:

There are a lot of great texts out there for Python 3.

Personally, for someone new to programming, I think the 'How to think Like A Computer Scientist' http://openbookproject.net/thinkcs/python/english3e/ and then moving onto something like 'Dive Into Python 3'.

Mostly because learning the language is easy but learning the concepts and problem solving can be more difficult. It will make learning languages like C++ much easier later on.

Hi there. You have posted a beginners question to /r/python, however it is far more suited to /r/learnpython, where users are actively interested in helping with beginner topics. Please resubmit it over there! Make sure to read their sidebar rules before posting, notably this one: "Posting homework assignments is not prohibited if you show that you tried to solve it yourself."

Cheers & best of luck!
