在我们这个技术驱动的社会中,小工具和硬件只是硬币更明显的一面。在这一章中,我们将讨论编程的基础知识。我们还将看看数字系统的可见部分:硬件。 到底什么是编程? 基本上,编程是告诉数字设备,比如你的个人电脑,做什么的行为。我们键入由编程语言定义的命令列表,以便发生有用或有趣的事件。正确编程的计算机运行着世界...

Sets optional environment variables for the debugger process beyond system environment variables, which the debugger always inherits. The values for these variables must be entered as strings. envFile Optional path to a file that contains environment variable definitions. SeeConfiguring Python environments...
However, before doing that, a few special variables are defined. __name__ is one such special variable. If the source file is executed as the main program, the interpreter sets the __name__ variable to have a value __main__. If this file is being imported from another module, __...
In mixed-mode debugging, these values present another child node labeled [Python view]. To view the variable's Python representation, expand the node. The view of the variables is identical to what you see if a local variable referencing the same object is present in a Python frame. The...
To refer to project properties or environment variables in <Target> element attribute values, use the property name within a $() token, such as $(StartupFile) and $(MSBuildProjectDirectory). For more information, see MSBuild properties. If you invoke a command like ($StartupFile) that use...
assign functions to variables: to call a function in python, we type the function’s name followed by a set of parentheses, e.g. the print function: print(). If we remove the parentheses afterwards, the function would not be called but python treats the function as object, in this case...

Use --include-plugin-directory only if you make __import__() calls that Nuitka cannot predict, and that come from a directory, for everything from your Python installation, use --include-module or --include-package. Note The resulting filename will be program.exe on Windows, program.bin ...
