    ...read the schema and generate the C++ code, then compile that generated code into the product. We needed a way to read the schema description file and output pieces of code that could be integrated into our C++ sources to be compiled with the rest of the product. Rather than write a program specific to our problem, I chose instead to write a general-purpose, although simple, code generator tool. It would solve the problem of managing small chunks of generator code sprinkled throughout a large co...

  • Python Success Stories

    ...reads new events from the data source. Each event needs to be filtered to determine whether it should be sent at all and, if so, translated into human-readable form. Finally, the event is sent through a common command line interface, OVO agent's opcmsg command. OVO agents have the ability to further modify an event's properties (e.g. provide automatic alarm closure). Event filtering and translation is controlled through configuration files, which are read in automatically both at start and whene...

  • Debugging Reference Count Problems

    ...reading section 1.2.1 of the Python/C API manual again, and then carefully read the descriptions of the functions you're calling. (I know, the manual is not complete; but it isn't *that* incomplete, and if you're finding a function that's not in the manual, reading its source usually gives a clue.) So says I (beginning to talk to self), why not print the environment in which the functions are being run to see what's going on... no sooner said than done. And the error disappeared!...

I'm not sure whether I depend on any software written in Python 2. What should I do? If you buy software or software support from vendors, ask them. If you pay developers or system administrators, ask them. If you don't have vendors or technical staff, then use "Can I Use Python 3?" to find out whether you depend on a...

  • Python Success Stories

    ...read this grid of numbers into Numeric arrays in Python. Originally quite a bit of preprocessing was involved to scale down the data to fit our internal model. We did not want to go through the reading and scaling process every time the program was launched because it was quite time consuming. Instead we were able to read and scale the data once, then Pickle the internal structure to a compressed file. Now the program had only to decompress the data and load it directly into the appropriate data...

  • Foreword for "Programming Python" (1st ed.)

    ...readable in two ways. First, the use of indentation reduces visual clutter and makes programs shorter, thus reducing the attention span needed to take in a basic unit of code. Second, it allows the programmer less freedom in formatting, thereby enabling a more uniform style, which makes it easier to read someone else's code. (Compare, for instance, the three or four different conventions for the placement of braces in C, each with strong proponents.) This emphasis on readability is...
