How to configure Python 2.7 on Windows 7?

+3 votes
148 views

I'm new to Python. I downloaded the 64-bit build of Python 2.7.10 from www.python.org/downloads/release/python-2710. I run Windows 7 Pro on a Dell PC.

I find that the installation package creates a folder called "Python 2.7" in my Start menu, with both a command prompt and IDLE GUI options.

I hold my scripts in another directory that is parallel to but not under the one where Python 2.7 resides, so I set the Environment Variable PYTHONPATH to include the directory where my scripts reside. Unfortunately, I am unable to reach them in either the IDLE GUI or the "Python command line" in that folder in my start menu. The only way I have managed to run Python scripts is to open an ordinary command prompt from Accessories, navigate to the directory with the scripts, and run python from the command prompt in that directory.

Can anyone let me know what I'm not doing that I should be doing to run Python and my scripts from the parallel directory under the GUI or the command line from the start menu folder ?

1) PYTHONPATH is used to specify where the Python interpreter will look for "import" modules from within a running Python script.

2) If the install (I have always used the ActiveState installs so don't know what plain Python does on Windows) has set up the environment such that ".py" files are executable, then putting the script directory on the regular system PATH should let you run them by entering their name in a command shell.

I want to install Python on a PC with the 64 bit version of Windows 7. I want Python to be able to use as much as possible of the RAM.

When I install the 64 bit version of Python I find that sys.maxint == 2**31 - 1 Whereas the Pythpon installed on my 64 bit linux system returns sys.maxint == 2**63 - 1.

It looks to me as though 32 and 64 bit versions of Python on 64 bit Windows are both really 32 bit Python, differing only in how they interact with Windows. So I wouldnt expect 64 bit Python running on 64 bit Windows to allow the large data struictures I could have with 64 bit Python running on 64 bit linux.

Is that true?I have spent a couple of hours searching for a definitive description of the difference between the 32 and 64 bit versions of Python for Windows and haven't found anything.

Manual says "-c Execute the Python code in command. command can be one or more statements separated by newlines, with significant leading whitespace as in normal module code."

In Windows Command Prompt I get:

C:ProgramsPython33>python -c "a=1nprint(a)"
 File "", line 1
 a=1nprint(a)
 ^
SyntaxError: unexpected character after line continuation character
(Same if I remove quotes.)

How do I get this to work?

I understand there have been changes to the way that extensions are supposed to be built for windows. Is there any user documentation regarding these changes?

Last time I looked the appropriate Visual Studio hadn't been release so I guess I will need to use my MSDN skills (or incantations) to first get that installed.
