Write a function new_cases (date, state) that takes in two strings representing a date and a two-letter state abbreviation, and returns an integer representing the number of new cases reported by the given state on that date.

You are permitted to import the csv module, but this is not required. Examples: >>> new_cases ('08/08/2020', 'MN') 797 >>> new_cases('11/21/2021', 'NE') 0 >>> new_cases ('01/05/2022', 'IA') 4268 >>> new_cases ('02/09/2023', 'MO') -1 >>> new_cases ('10/22/2020', 'QQ') -1

In python

Download the hw08files.zip folder from Canvas, and extract the files. Create your hw08.py file in the same directory as the extracted files: all of the test cases for this assignment will assume that your Python file is in the same folder as the sample files. Open up the covid_data.csv file provided and browse the data. This CSV file was obtained from the CDC website: [CDC COVID-19 Data](https://data.cdc.gov/Case-Surveillance/United-States-COVID-19-Cases-and-Deaths-by-State-o/9mfq-cb36). It contains data reported by each state about the number of COVID-19 cases in the state on various dates. The columns you’ll need to use in this problem are as follows: - **First column: submission_date** - This column contains the date each data point was submitted. - **Second column: state** - This column contains a (usually) two-letter abbreviation for the state submitting the data. - **Sixth column: new_case** - This column contains the number of new COVID-19 cases detected since the last report from that state.

### Function Definition: `new_cases(date, state)` **Objective:** Develop a function `new_cases(date, state)` that accepts two parameters: - `date`: A string representing a specific date. - `state`: A two-letter string representing a state abbreviation. This function returns an integer indicating the number of new COVID-19 cases reported by the specified state on the given date. **Special Condition:** If no data exists for the provided state/date combination, the function should return `-1`. **Data File Assumption:** It is assumed that there is a CSV file named `covid_data.csv` in the same directory as the script file `hw08.py`. This CSV file is formatted identically to an example provided to the user. **Module Usage:** You are allowed to use the `csv` module, though its use is optional. ### Examples ```python >>> new_cases('08/08/2020', 'MN') 797 >>> new_cases('11/21/2021', 'NE') 0 >>> new_cases('01/05/2022', 'IA') 4268 >>> new_cases('02/09/2023', 'MO') -1 >>> new_cases('10/22/2020', 'QQ') -1 ``` These examples demonstrate the function's expected output for various inputs, including scenarios where the data is unavailable, resulting in a `-1` return value.
