如何在Python语言中解析iCal日历文件的类别组件

pip install icalendar

import icalendar

def parse_ical(file_path):
    with open(file_path, 'rb') as file:
        calendar = icalendar.Calendar.from_ical(file.read())

        for event in calendar.walk('VEVENT'):
            if 'CATEGORIES' in event:
                categories = event['CATEGORIES']
                if isinstance(categories, list):
                    for category in categories:
                        print('Category:', category)
                else:
                    print('Category:', categories)

# 示例使用
parse_ical('calendar.ics')
