The following is how I’d recommend getting started programming in Python:

1. The Python Tutorial .
   First off work your way through the official Python tutorial, its very comprehensive and covers all the language features and also has a quick tour of the modules available in the standard library.
2. Code Like a Pythonista: Idiomatic Python
   Next I’d highly recommend reading the ‘Code Like a Pythonista‘ article is its entirety, its very useful for learning about the Pythonic way of thinking.
3. The Python Style Guide.
   Next read the Python Style Guide (know as PEP-8), which will teach you about the general python coding style which depending on the languages you’ve used before could be quite a different style.
4. The Python Challenge.
   Now try the Python challenge, this will push your new Python skills and riddle solving abilites.  If you get stuck the official forums are helpful, I found I got stuck on the riddles more than the programming.  Once you’ve solved each of the challenges I’d strongly recommend going and checking out the submitted solutions to that challenges.  I found this a incredibly helpful learning experience, as by looking at the solutions I learned the pythonic way to solve the problems.  Note: you can’t access these solutions till you’ve solved them yourself.
5. ‘Learn Python the Hard Way’ or ‘Dive into Python’.
   For gaining further knowledge there are several ebooks available online for free: the first is Learn Python the Hard Way and there is also the dated Dive into Python.  I’ve not read Learn Python the Hard Way but I’ve heard good reviews from several people.

For getting help with Python programming I’d recommend:

• Stack Overflow.
  Stack Overflow is a collaborative quesion and answers site for programmers and has a very active python community.  It is highly recommended to searching to see if your question has been asked already before  posting a question.
• #python on irc.freenode.net.
  Visiting the #python IRC channel on irc.freenode.net is also a very good way to get help with Python questions.  You can find our more about the various Python IRC channels here.  Note: You’ll need an IRC client like X-Chat (Linux & Windows) or Colloquy (Mac).

Here are some tools I’d recommending picking up:

• Package installer – PIP or easy_install.
  PIP is the current Python package installer of choice and lets you easily download and install Python from various sources such as the official Python package repository – PyPi and SourceForge.  I found that PIP makes installing new Python packages trivial 99% of the time, the other 1% of the time you’ll need to build the packages locally which is more involved.  Note: Windows users may be better off sticking to the older easy_install tool instead of PIP.
• Enhanced command line – iPython or bPython.
  iPython is an enhanced command line environment for Python that I’d highly recommend over the basic command line interpreter.  You can find several different  of video tutorials for iPython listed here. I am told that bPython is another enhanced command line that is worth checking out too.
• Code analyser – PyLint or pyflakes.
  PyLint is a python version of the Lint C/C++ static code analysis tool which will analyse your Python code and give you useful feedback on your code as well as a score out of 10.  PyLint will also check your code adheres to the official Python Style Guide which I found very useful for learning the Python coding style.  Alternatively pyflakes has also been recommended for static analysis of python code.

I’d be interested in hearing of any other resources you found useful to help you get started with python.
