Short Python Code for Raspberry Pi Ultrasonic sensor model. (Just write code for me)

Requirements: 1. Continous distance measurement when sensor comes in range. Saves to a csv file through wifi module rpi. 2. Turns on the red led and displays "Alert: Impending collision" and LCD when distance goes below a threshold. Also, the sound buzzer rings. Saves distance to a csv file. 3. Turns on the yellow led when distance goes below second threshold and displays on LCD "Brake applied". Also, saves to csv. Please refer the circuit diagram provided in the files. I have already setup my Raspberry pi that way. Also, the pin positions are shown by screenshot. A sample python program for distance measurement is also uploaded.
