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!
