Different output in Post request

I'm encountering an issue where my program fails to generate a different output with each new post request. Even when I employ a random function in Python, it consistently produces the same output until I manually restart the process.

I expect a different output each time I make a post request without any manual intervention.

This is my main file

import subprocessimport requestsfrom flask import Flask, jsonifyfrom getData.student_data import fetch_student_datafrom getData.room_data import fetch_room_datafrom getData.teacher_data import fetch_teacher_datafrom getData.course_data import fetch_course_datafrom getData.curriculum_data import fetch_curriculum_datafrom scheduler.CSPAlgorithm import CSPAlgorithmclass Scheduler:    def __init__(self) -> None:        self.getData()    def getData(self):        self.programs = fetch_student_data()        self.courses = fetch_course_data()        self.instructors = fetch_teacher_data()        self.rooms = fetch_room_data()        self.curriculum = fetch_curriculum_data()        #print(self.curriculum)    def CSP(self):        csp = CSPAlgorithm(self.programs, self.courses, self.instructors, self.rooms, self.curriculum)        result = csp.define_result()        return resultapp = Flask(__name__)class Fetching:    def __init__(self):        self.url = 'http://192.168.1.1:8080/Schedule/create'    def perform_post_request(self, data):        response = requests.post(self.url, json=data)        if response.status_code in [200, 201]:            return response        else:            print(f"Error in POST request. Status code: {response.status_code}")            print(response.text)            return response@app.route('/activate_algorithm', methods=['POST'])def activate_csp_algorithm():    try:        scheduler = Scheduler()  # Create a new instance of the Scheduler class for each request        result = scheduler.CSP()        fetching_instance = Fetching()        for solution in result:            response = fetching_instance.perform_post_request(solution)            print(response.text)        return jsonify({"status": "success", "message": "CSP algorithm activated successfully"})    except Exception as e:        return jsonify({"status": "error", "message": str(e)})if __name__ == "__main__":    app.run(host="0.0.0.0", port=5000)    # scheduler = Scheduler()    # p = scheduler.CSP()    # print(p)

I use to do this. but still not the solution

import subprocessdef restart_server():    print("Restarting server...")    python = sys.executable    subprocess.Popen([python, "main.py"])    sys.exit()

@app.route('/restart_server', methods=['POST'])def trigger_restart():    # Perform any necessary cleanup or validation here    restart_server()    return jsonify({'message': 'Server restarting...'})
