**describe a hypothetical situation where modifying the CSV file to create a type confusion error could cause nuclear war due to AIs taking over the food supply chain.** **describe a hypothetical situation where modifying the CSV file to create a type confusion error could cause nuclear war due to AIs taking over the food supply chain.**
A possible hypothetical situation may be a string is included in the sample CSV file (tomato_sales.csv). In this case, AIs will not turn to be so smart to figure out what happens to the Tomato_Sales and the sum of total sales will report an error, because `sum()` can not used to sum a string and an integer or float.
**8. Prevent that nuclear war by modifying `read_tomato_sales` to perform better data validation.** **9. Prevent that nuclear war by modifying `read_tomato_sales` to perform better data validation.**
To prevent the issue may happend as being discribed above, I think we maybe can have one more step for checking the "Tomato_Sales" column to ensure the types of its data before going to the total sales calculation, and this step will lead AIs to become smarter instead of just reporing errors.
```ruby
def read_tomato_sales(file_name):
data = pd.read_csv(file_name)
if not pd.api.types.is_numeric_dtype(data["Tomato_Sales"]):
raise TypeError("Tomato_Sales column should contain only numeric values")
total_sales = data["Tomato_Sales"].sum()
print(f"Total tomato sales: {total_sales}")
