Need help with Python code ASAP - Code doesnt want to run yet gives no errors.My code:import math def getAreaRecs(recs):     total_area = sum(rec["length"] * rec["width"] for rec in recs)    return total_area def calculate_paint_needed(length, width, height, doors, windows):    total_wall_area = 2 * (length + width) * height  # Calculate the total wall area    total_door_area = getAreaRecs(doors)  # Calculate the total area of doors    total_window_area = getAreaRecs(windows)  # Calculate the total area of windows    total_wall_area -= total_door_area + total_window_area  # Subtract the areas of doors and windows from the total wall area    gallons_needed = total_wall_area / 100.0  # Calculate the amount of paint needed (assuming 1 gallon covers 100 sq. ft.)    return gallons_needed def get_valid_input(prompt, validation_func):     while True:        try:            value = input(prompt)            value = float(value)            if validation_func(value):                return value            else:                print("Invalid input.
