  ...files can be shipped to clients regardless of target platform, making support quite easy. Speed, Scalability, and Stability When we started to write in Python, our previous experience in compiled languages led us to believe that we would be spending a fair amount of time either optimizing code or converting it into C or C++ once we had prototyped it. As it turned out, most of the time Python produced a snappy end product that didn't require any extra work. This happened partially because most ...

• Computer Programming for Everybody

  ...file intermingled with four changes to function Z at the bottom of the file. Now the programmer discovers that function A should never have changed; selective undo allows changes to function A to be rolled back without affecting the changes to function Z. Global undo is similar to what version control provides, where system level changes can be tagged and rolled back when they adversely affect the system. Where global undo differs however is that no a-priori decision has to be made about ...

• IDLE and tkinter with Tcl/Tk on macOS

  IDLE and tkinter with Tcl/Tk on macOS Important If you are using macOS 12 Monterey or later, you may see problems with file open and save dialogs when using IDLE or other tkinter-based applications. The most recent versions of python.org installers (for 3.10.0 and 3.9.8) have patched versions of Tk to avoid these problems. They should be fixed in an upcoming Tk 8.6.12 release. If you are using a Python from any current python.org Python installer for macOS (3.10.0+ or 3.9.0+), no further acti...

• Glue It All Together With Python

  ...files containing function and method prototypes and automatically generates the necessary type conversion and error checking code. In situations where the underlying code (usually C code) doesn't use an object-oriented model, the glue extension can in turn be wrapped in a Python module that defines a proper class hierarchy, while delegating the performance critical operations to the C code. Using Python, better applications can be developed because different kinds of programmers can w...

  ...files too? The 't' mode conflicts with the use of this mode on Windows to be an explicit way to invoke the default text translation mode. Why can't 't' be used together with '+'? Text mode on Windows supports '+' AFAIK. How does this interact with xreadlines? With "for line in file" ? Why settle for a compile-time option that's off by default? That's asking for problems; people who turn it on will write code that uses the 't' mode and then find that it's not portable. ...

  ...files, or write other supporting code required in languages like C++ or Java. As a result, Python is almost executable pseudo-code. Python speeds the development cycle. Since Python code is compiled to byte code on the fly by the interpreter, the development cycle is just "edit-and-execute" instead of "edit-compile-execute". In practice, this can save substantial amounts of time. Python facilitates debugging. Python's detailed tracebacks reveal the cause of problems very qu...

Complicating the issue was the challenge of finding money to improve the flight design process in an era of declining budgets for space activities. "Just in time" provides a solution--and more problems USA decided they needed a way to "minimize data changes and the resulting rework." The shortest route to...

This provided the developer with a graphical animation of the movement of the spindles, air cylinders, and the status of the sensors. The simulator allowed the software developer to start building the control software before the hardware design and assembly were complete. It also acts as a convenient way to debug and s...

Due to the mysteries of Usenet, the order in which items show up may vary. Rudeness and personal attacks, even in reaction to blatant flamebait, are strongly frowned upon. People may strongly disagree on an issue, but usually discussion remains civil. In case of an actual flamebait posting, you can ignore it, quietly plonk the offending poster in your killf...
