Python：在csv行中编写int和list

import csv

data = [
    {'name': 'Alice', 'age': 30, 'hobbies': ['reading', 'hiking']},
    {'name': 'Bob', 'age': 25, 'hobbies': ['swimming', 'gaming']},
    {'name': 'Charlie', 'age': 22, 'hobbies': ['music', 'traveling']}
]

with open('output.csv', 'w', newline='', encoding='utf-8') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=['name', 'age', 'hobbies'])
    writer.writeheader()

    for row in data:
        writer.writerow({
            'name': row['name'],
            'age': row['age'],
            'hobbies': ', '.join(row['hobbies'])
        })
