Introduction
This document describes the Python interface to the Systems Biology Workbench (Hucka et al., 2001b).

The Python interface has been designed so that it is very simple to call remote methods in other SBW aware modules. The intention in developing the Python module was that if should enable users to easily control SBW applications using Python scripts.

In addition to providing simple access to SBW modules, the Python interface also exposes many of the functions in the standard SBW API. The reader is recommended to consult the SBW API documentation for more details. In the majority of cases, users will not find it necessary to access the SBW API directly.

When a SBW module starts, Python is notified and a Python interface is automatically constructed to represent the module, this makes it very easy to access a module’s functionality.

PROGRAM STANDARDS

1. A template program ZTEMPLATE in client 110 has been provided for your convenience. Please be careful not to update this program directly. Copy it to your new program name, and then modify your program. Be sure to change the “Title” field on the attribute page of your program to reflect a description of what your program does.
2. All programs should include a comment box at the beginning of the program listing the following information (see ZTEMPLATE):
   1. Program name
   2. Author
   3. Date written
   4. Description of the program. Be sure to list any special considerations and/or situations. List any tables being used, with a brief description of the table.
   5. All modifications to the program should also be documented in this area. (See Coding Standards: Source Code Document for more information.
3. Use descriptive data and paragraph names. Do NOT use a hyphen “-“ in variable names or in paragraph (“form”) names. Use the underscore “_” instead. SAP uses the hyphen “-“ to separate a table name from the field name in the table. Using an underscore will increase readability of your program.
4. Group parameters and select-options together. Group table names together. All data items should be at the beginning of the program before any event logic.
   1. Names of parameters and select-options are limited to 8 characters.
   2. Table names are limited to 16 characters.
5. Event paragraphs should be listed in a logical order inside of a START-OF-SELECTION …END-OF-SELECTION section.
6. Use indentation to make the reading of your program easier. This is automatically set when you use Pretty Printer (see Code Standard: Formatting).
7. Screen frame titles should be constructed using standard Title Case.
8. All emails generated from SAP programs should use proper grammar and punctuation and appropriate line-wrapping.

For a climbing expedition in Peru that I did recently, I needed a digital camera that could take great still images, but it also had to shoot full frame video at 30 fps (frames per second), work well in very cold conditions, and use AA batteries for power (since there wouldn’t be any place to plug in a camera battery charger high in the mountains). For those combined requirements, the field quickly shrank to just a few cameras. It did all those things, shooting 2 gigabytes of images and video for nearly 4 weeks on just one set of lithium AA batteries! I studied a great many camera specifications in order to narrow my choice correctly and I’m including the things I had to consider here in the belief that they will also serve you well if you’researching for a consumer or snapshot digital camera.
