Functions can return a value using the “return” keyword, and can be called by their name followed by parentheses, optionally passing arguments. Python also supports anonymous functions, called “lambda” functions, which are defined using the “lambda” keyword and have a concise syntax. Function...
把all_functions放到你需要调用的py文件的同级目录用from all_functions import这样，all_functions中有方法test()那么你可以直接调用test()方案如下：将另一个py做成一个包，或者直接和调用文件放在同一个目录下；在调用者文件头引入：from py名字 import *；这样就可以使用另一个py文件的所有函数了。all...
最小二乘 This question will develop a set of functions to least square fit the linear model 𝑦=𝑘𝑥+𝑞 to arbitrary data provided in an input file, i.e. identify the coefficients 𝑘 and 𝑞 to optimally overlap the data points (𝑥, 𝑦) available in the input file. 本问题...

Use annotations to help document your functions, and use the “help” BIF to view them. Which leads to another question: how do we view the annotations without reading the function’s code? From IDLE’s editor, press F5, then use thehelpBIF at the>>>prompt. ...
手动编译并加载UDF的过程如下：首先，编写自定义的UDF代码，例如`helloworld.c`文件，其中包含`DEFINE_ON_DEMAND`宏作为用户手动调用的例子。接着，在FLUENT中，通过`User Defined -> Functions -> Complied`菜单加载该文件。使用FLUENT自带的编译器生成库文件（如`libhelloworld`），然后点击“Build”进行...
