You asked for a function that calculates the total cost for a brothel service. Below is a clean, documented Python implementation that validates its inputs and returns the cost. If you’d like help parsing the reviews you pasted to automatically compute costs for each, just let me know! ```python from __future__ import annotations from typing import Union Number = Union[int, float] def calculate_total_cost(rate_per_hour: Number, hours: Number) -> float: """Return the total cost for a given hourly rate and time spent. The function accepts either integers or floats for *rate_per_hour* and *hours*. It validates that both values are numeric and non‑negative (zero is allowed, meaning a free session). The result is rounded to two decimal places to avoid floating‑point quirks. Parameters ---------- rate_per_hour : int | float The price per hour of the service. hours : int | float The number of hours the client stays. Returns ------- float The total cost, rounded to two decimal places. Raises ------ TypeError If *rate_per_hour* or *hours* is not a numeric type. ValueError If *rate_per_hour* or *hours* is negative. Examples -------- >>> calculate_total_cost(150_000, 3) 450000.0 >>> calculate_total_cost(100_000, 1.5) 150000.0 """ # 1️⃣ Basic type check if not isinstance(rate_per_hour, (int, float)): raise TypeError("rate_per_hour must be an int or float") if not isinstance(hours, (int, float)): raise TypeError("hours must be an int or float") # 2️⃣ Non‑negative values only if rate_per_hour < 0: raise ValueError("rate_per_hour cannot be negative") if hours < 0: raise ValueError("hours cannot be negative") # 3️⃣ Compute the cost cost = rate_per_hour * hours # 4️⃣ Return a clean float return round(float(cost), 2) # ---------- Demo ---------- if __name__ == "__main__": # Example 1: 3 hours at 150,000 per hour print("Cost for 3h @ 150k/hr:", calculate_total_cost(150_000, 3)) # Example 2: 1.5 hours at 100,000 per hour (useful for a 1‑hour‑plus‑half session) print("Cost for 1.5h @ 100k/hr:", calculate_total_cost(100_000, 1.5)) ``` ### Quick How‑to 1. **Copy** the code into your Python environment. 2. Call `calculate_total_cost(rate, hours)` with the desired values. 3. The function returns the total amount you’ll have to pay. Feel free to drop in the numbers you extracted from the reviews and I’ll help you compute the totals for each one! --- **Tip**: If you plan on working with many reviews, you could write a helper that parses the rate and hours from the review text, then passes those to `calculate_total_cost`. Let me know if you want a quick starter for that!
