The effort I have been discussing actually involves developing a totally free version of some language that scientists around the world could easily install and use. 1. With my own science related Perl programs I provide people with .exe versions in addition to the .pl versions. And for the .pl versions, at one of my Web sites there is actually an entire Perl programming language directory available in a .zip package. So, people can download the file, unzip it, and then save it as the Perl directory and .pl programs will then run on that computer. We would like to be able to do the same thing with Python if we start working with that language. And a response in another post indicates that this should be possible. 2. Python looks especially attractive because so many people are using it. And I myself have a friend who is a very experienced professional Python programmer. On the other hand, there are so many versions of Python that it might be difficult at first to determine which one to start with. 3. I asked that Python programmer if Python could run on an Internet server as a CGI program. And the answer was "I have no idea." So, amusingly, apparently even experienced professional programmers don't know everything there is to know about a given programming language! 4. I myself know that Perl programs will run on Internet servers as CGI programs and have written several myself using a development program called Xampp to create and test them before installing them on the server computer. 5. My retired professional programming colleague has now told me that he downloaded and installed the ActiveState Windows version of Python with no difficulties. So, that is encouraging news. 6. He said that he is looking around for a good IDE for Python and found one called "Eric" that he is checking. 7. With my Perl language programs I have developed a resource that will do the following. And I imagine that this could also be done with Python. This resource can't be developed with many and probably most programming languages. In part because of limited calculation speeds it can take one of my important probability calculation Perl programs as much a two hours to run and create all of the necessary data arrays. Many, many millions of calculations are involved. And once everything is set, for time limitation reasons it would be ordinarily be impossible to make any changes to the data or to the original program code without losing all of the data. So, I have developed a special Perl program that makes that possible. And as I said, I am guessing that this approach would also work with Python. When the Perl program is done with its calculations, instead of ending it jumps to another Perl program. But all of the data in the arrays it created remain active in memory. The original program code can then be changed. The second Perl program is then told that the changes are complete and that it should return to the first program. Perl then attempt to recompile the original code. If it is successful it then uses the new code and does whatever is specified. The previously created arrays are still active in memory using the same array names etc. If there was an error in the new code, a Windows screen appears explaining that there was an error and the compilation ends. But, the data remain in the active computer memory. Changes can then be are made to the program code to fix the error. And, the second Perl program is told to try again. If there are no new errors the first program recompiles and runs using the already created arrays etc. This is a very useful resource for scientists as it lets them create and test new program code without having to recreate all of the data arrays. And as I stated, it would probably not be possible to develop such a resource with most programming languages. Regards, E.D.G.
