在rule_engine.py文件中,添加调用引擎和进行推理的代码。 # rule_engine.pydefrun_engine():engine=knowledge_engine.engine('path/to/your/rules')# 创建知识引擎engine.activate('Example_Rule')# 激活指定规则# 结果可以输出或存储print("规则引擎已运行")if__name__=="__main__":run_engine() 1. 2....
Example:if isstudent = (bool)1 then discount=float(0.7) 1. 规则解释:当 是否学生 为“是” 则 折扣为0.7 如果不强制控制类型那么所有类型默认为string类型 支持最多两条结果输出: 在编写rule.txt的时候,支持一个条件满足,两个输出 Example:if function = (string) video then cpu=i3 and type=轻薄 解...
class Rule: def __init__(self, condition, action): self.condition = condition self.action = action def evaluate(self, facts): if self.condition(facts): self.action(facts) def rule_engine(rules, facts): for rule in rules: rule.evaluate(facts) # 定义规则 rules = [ Rule( condition=lamb...
良好的 Python 代码应有良好的格式规范(不止于遵守PEP 8),使用一个更强大更专业的代码格式化工具,来替代编辑器自带的「格式化代码」功能是有一定必要的,这还可以使团队成员即使在不同编辑器下工作也可以得到完全相同的风格。相比于目前中文社区中较为流行的autopep8,其实还有一个更好的选择 ——Black。 Life is ...
python3 metaclass_example.py Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", line 6, in __init__ AttributeError: HANDLER_INFO is not callable 从输出中可以看出,一旦解释器解析了类日志的定义以创建类,元类__init__方法就会被调用,验证类的属性并引...
Example Usage The following example demonstrates the basic usage of defining a rule object and applying it to two dictionaries, showing that one matches while the other does not. SeeGetting Startedfor more information. importrule_engine# match a literal first name and applying a regex to the ema...
For example, the path C:\Users\Real Python\main.py corresponds to the following hierarchy in the Windows file system: C: └── Users └── Real Python └── main.py Each line in the tree above represents an individual component of this path. The first line is the drive letter (C...
Below is an example that demonstrates the specifics of rounding with these methods: PythonCopy Code import math def Rounders(): PositiveFloat1=123.456 PositiveFloat2=123.567 NegativeFloat1=-123.456 NegativeFloat2=-123.567 Log.Message("Using the Floor method") Log.Message(math.floor(PositiveFloat1))...
save("example.xls") 说明: xlwt 是一个用于写入Excel文件的库,仅支持xls格式,适合需要创建旧版Excel文件的场景。 pandas 安装: pip install pandas 使用示例: import pandas as pd # 读取Excel文件 df = pd.read_excel("example.xlsx") # 写入Excel文件 df.to_excel("output.xlsx", index=False) 说明: ...
The Python engine has access to all parts of the simulated system and can interact with all Simics API calls. CLI and Python scripts can exchange data and variables with each other, and it is common to find snippets of Python embedded inside of Simics scripts. An example Simics script is ...
