Eventually, you will need to debug larger programs — programs that use subroutines. And sometimes, the problem that you're trying to find will lie buried in a subroutine. Consider the following program. # epdb2.py -- experiment with the Python debugger, pdb import pdb def combine(s1,s2):...
NSAppleScript/NSUserAppleScriptTask/OSAKit are a huge chore, and osascript is only good for very simple tasks. Your best option is to use AppleScriptObjC if possible, as that handles all the ObjC/Swift↔︎AS bridging for you, allowing you to call your AS handlers much as if they w...
This can even be used in asubroutine,Echo %0 will give the call label but,echo "%~nx0" will give you the filename of the batch script. When the %0 variable is expanded, the result is enclosed in quotation marks. Use%~a1 to display the Extended Attributes of a file. FOR's%%~aI ...

embedding, in which the end-user launches a program written in C++ that in turn invokes the Python interpreter as a library subroutine. Think of adding scriptability to an existing application. 组合C++和Python有两种基本模式: 扩展: 最终用户运行Python解译器程序,并导入用C++编写的Python“扩展模块”。

The code block below demonstrates how to check if a file exists using the Dir() function. The Dir() function is a powerful tool to get folder names and file names by using their file paths. The code block below contains a subroutine with a fileToCheck parameter. You can call the Check...
To get started, look for places where you can use VBA in your work. When should you use VBA? A lot of what you will need out of Microsoft Excel you can do with formulas, copying and pasting, and selecting a range of cells. The basic functionality of Excel does its job really well,...
1. Write a subroutine (procedure, etc.), called ADDXY, that takes as input two scalars, x and y, and produces x + y as output. Write a program that reads two scalars, x and y applies ADDXY to x and y, and prints the answers in a readable fashion. "THE SUM OF x AND y IS ...
