Python Function: Get Scores of Selected Names from a List

Here is an implementation of the get_scores_of_selected_names() function in Python:

from typing import List
from collections import namedtuple

StudentScore = namedtuple('StudentScore', ['name', 'score'])

def get_scores_of_selected_names(selection: List[str], scores: List[StudentScore]) -> List[StudentScore]:
    '''
    Given a list of student names and a list of student scores, returns a list of 
    namedtuples containing the names and scores of the selected students.
    '''
    selected_scores = []
    for student_score in scores:
        if student_score.name in selection:
            selected_scores.append(student_score)
    return selected_scores

# Example usage:
scores = [
    StudentScore('li', 30),
    StudentScore('hu', 23),
    StudentScore('huai', 99)
]
selection = ['li', 'huai']
for student_score in get_scores_of_selected_names(selection, scores):
    print('{} - {}'.format(student_score.name, student_score.score))

This function takes a list of student names (selection) and a list of StudentScore namedtuples (scores) as input. It iterates through the scores list, checking if each student's name is present in the selection list. If a match is found, the corresponding StudentScore namedtuple is added to the selected_scores list, which is returned as the final output.

The example usage demonstrates how to use the get_scores_of_selected_names() function with a sample dataset. It prints the names and scores of the selected students, showing the output of the function.
