Write a function build_csv_string(data) that takes in a list data. data will be a list of lists, where each sub list is of length 1, 2, or 3. Length 1 lists will contain a name (as a string). Length 2 lists will contain a name and an assignment title (as a string). Length 3 lists will contain a name, an assignment title, and a score (as a float or int). The function should return a valid csv string where each sublist is a record in the string. The header (first line) of the csv file should be 'name, assignment, grade\n'. Lists missing a grade value should use as the default, and missing assignment titles should be defaulted to 'N/A'

In python
Transcribed Image Text:### Function Definition: build_csv_string(data)
This function, `build_csv_string(data)`, processes a list of lists, `data`, and converts it into a CSV string. The structure of each sublist is variable, where the length can be 1, 2, or 3, and each length has specific content requirements:
- **Length 1**: Includes only a name (as a string).
- **Length 2**: Includes a name and an assignment title (both as strings).
- **Length 3**: Includes a name, an assignment title, and a score (as either a float or an integer).
### Function Purpose
The function's goal is to return a CSV-formatted string where each sublist represents a record. The first line of the CSV string serves as a header and should be formatted as: `'name, assignment, grade\n'`.
### Handling Missing Data
- **Missing Grade**: Sublists that lack a grade should default the grade value to `0`.
- **Missing Assignment Title**: If the assignment title is missing, it should default to `'N/A'`.
Through this approach, the function ensures a consistent output format, handling any incomplete data by providing sensible defaults.
