使用带引号的多行字符串解析CSV

import csv

def parse_csv(csv_string):
    reader = csv.reader(csv_string.splitlines())
    records = []
    for row in reader:
        record = []
        for field in row:
            if field.startswith('"') and field.endswith('"'):
                # 去除字段两端的引号，并处理引号内的引号转义
                field = field[1:-1].replace('""', '"')
            record.append(field)
        records.append(record)
    return records

csv_string = '''
"Name","Age","City"
"John Doe","25","New York"
"Jane Smith","30","San Francisco"
'''

parsed_data = parse_csv(csv_string)
for record in parsed_data:
    print(record)

['Name', 'Age', 'City']
['John Doe', '25', 'New York']
['Jane Smith', '30', 'San Francisco']
