PyIO 1.0

You can download the PyIO 1.0 by clicking here. There are four files in the zip file: (these two are the main files for PyIO application), PyIOmanual.pdf (the PyIO manual), and (containing files used in the examples in PyIOmanual.pdf). You can copy the first two files to your working directory, and start the PyIO session from there by double-clicking the

The manual to the PyIO module is written by Suahasil Nazara, Carolyn Dong Guo, Geoffrey Hewings, and Chokri Dridi  (2003) and is published as a REAL Discussion Paper 03-T-23. Please make appropriate reference to this manual if you are using the code.

I want to install Python to run the PyIO 1.0  What should I do?

While we are aware that Python is frequently updated – at the moment this website is created, version 2.3 (beta) is the latest there – we suggest users to use Python version 2.2. We actually heard that PyIO also works fine with version 2.3, but no thorough test is done for that.

The installation of Python should be done in the three steps as the following:

First, install Python version 2.2. For Windows user, you should download Python-2.2.3.exe and double click this file to install Python version 2.2.

Second, install the Windows Extension for Python version 2.2. Download Mark Hammond’s Python for Windows Extensions ( which for Python version 2.2 is named win32all-152.exe.

Third (only after these two files are properly installed in your computer), you should also install the Numerical Python (Numpy), a module for numerical array computation. Windows user should install Numeric-23.0.win32-py2.2.exe. Once again, Numpy should be installed only when you have the first two files properly installed in your computer.

Having installed all of the three files, you are ready to use PyIO. You can start by double clicking

What hardware is required?

Any Pentium-level computer should be able to run Python and PyIO. The limit is more on the software. The current version of PyIO is intended only for Windows user. We are really sorry that we cannot accommodate Mac and Linux users. All of the functions in PyIO offers an output in Microsoft Excel format. If you want this, naturally the Microsoft Excel should be properly installed in your computer. For those who do not want Excel output, PyIO will automatically write the results in an ASCII text file.
