Python 3 - Installing - On Windows 7

First of all, let's download the last version of Python 3 on the official website of Python : http://www.python.org/download/releases/

I suggest you to select the last one. And of course to choose the right version of your Operating System (OS).

For this Python tutorial on Windows 7, we will take, of course, the Windows X86-64 MSI Installer because the installation is under Windows 7 - 64 bits.
If you do not know if your Windows 7 is 64 bits or not, choose the Windows x86 MSI Installer.
This version will work on both 32 and 64 bits, so do not hesitate to take it in any doubt.

OK, once you downloaded it, just launch the .msi file.
A window appears, install it for all users or just for you.

Then select the installation directory. I suggest you to create a new one called soft and to install all your software inside.

Why? Because sometimes software do not like spaces between words and simply do not work at all if there are spaces in the path.
A good example is Apache Ant.
So let's create our new directory:

C:\soft

So we are going to install Python 3 in this directory:

C:\soft\python\python3

Click Next.

Select all features and Next.

The installation begins.

Click Finish.

Let's try it, just to see if it works.

Go in the installation directory and double click python.exe.

A new black window will appear displaying something like that:

Python 3.2.1 (default, Jul 10 2011, 20:02:51) [MSC v.1500 64 bit (AMD64)] on win
32
Type "help", "copyright", "credits" or "license" for more information.

If you got it, Python 3 is now installed on your computer.

Well done!
