Step 1: Installing PyKE
Before we begin, let's make sure you have PyKE installed on your system. If not, you can easily install it using the following command:
```bash
pip install pyke
```
Step 2: Importing the Necessary Libraries
We'll start by importing the required libraries for working with PyKE. These libraries will help us build our expert system.
```python
from pyke import knowledge_engine
```
Step 3: Defining Course Facts
Facts are the foundation of our expert system and represent knowledge about various Python courses and their attributes. Below are some of the Python course facts we've gathered:
```python
facts = '''
course("Introduction to Python", "beginner", "programming")
course("Advanced Python", "intermediate", "programming")
course("Data Science with Python", "intermediate", "data science")
course("Python for Web Development", "intermediate", "web development")
course("Python for AI and Machine Learning", "advanced", "artificial intelligence")
course("Python for Game Development", "advanced", "game development")
'''
```
Step 4: Creating Rules for Better Decision-Making
Now, we'll define the rules that our expert system will follow to make logical decisions. These rules consist of a head (the conclusion) and a body (the conditions).
```python
rules = '''
python_beginner_course(course_name) IF course(course_name, "beginner", "programming")
python_intermediate_course(course_name) IF course(course_name, "intermediate", "programming")
python_data_science_course(course_name) IF course(course_name, "intermediate", "data science")
python_web_dev_course(course_name) IF course(course_name, "intermediate", "web development")
python_ai_course(course_name) IF course(course_name, "advanced", "artificial intelligence")
python_game_dev_course(course_name) IF course(course_name, "advanced", "game development")
'''
```
Step 5: Your Goal - Finding the Perfect Python Course
Our ultimate aim is to recommend the ideal Python course for you, tailored to your specific needs. In this case, we are searching for a course that suits advanced learners with an interest in artificial intelligence.
```python
goal = 'python_ai_course(course_name)'
```
Step 6: Building the Knowledge Base and Loading Facts and Rules
Now, we'll create the Knowledge Base (KB) and load the facts and rules to empower our expert system with the necessary knowledge.
```python
engine = knowledge_engine.engine(__file__)
engine.activate('python_programming')
engine.add_kb('python_programming', 'e', facts=facts, rules=rules)
```
Step 7: Reaching Your Goal - Get the Best Course Recommendation
With our expert system ready, it's time to achieve your goal. Let's find the perfect Python course for you!
```python
print("We recommend the following Python course for you:")
for plan in engine.prove_1_goal(goal):
print(plan['course_name'])
```
Conclusion
You now have access to our expert system built using PyKE, designed to help you find the most suitable Python course. Personalized course recommendations based on your skill level and interests will undoubtedly enhance your learning journey. Feel free to explore more courses and rules to improve our expert system further. Happy learning!
