There may already be a 64-bit Python installed without your knowing it, and this will cause problems with the installation of numpy and matplotlib. If you subsequently see a dialog box resembling Figure 2 below for any version of Python 3, select Remove Python for that version. You should be greeted by a dialog box resembling the following:– Do not install this! It is the 64-bit version, and it is not compatible with the currently available version of numpy.ĭouble-click on the file python-3.4.0.msi to start the installation.

The reason is that the official release of numpy is currently available for Windows only in 32-bit format. However, the 32-bit version of Python can run on both 64-bit Windows PCs and 32-bit Windows PCs.įor getting started, we must use the 32-bit version of Python on Windows. Fortunately, most Windows PCs sold over the past few years are 64-bit. Obviously, the 64-bit version requires a 64-bit Windows computer. There are two variants of Python 3.4 for Windows - a 32-bit version and a 64-bit version. Programs written for versions of Python 2 will not necessarily run on Python 3 installations if they do run, they may get different answers to the same problem. The Python 3 language is cleaner, more self-consistent, and more user-friendly. ![]() Significant changes to the Python language were made between Python 2.x and Python 3.y (for all values of x and y).
