读取字符串的CSV并将其格式化为无引号或方括号

import csv

def format_csv_string(csv_string):
    # 将CSV字符串转换为二维列表
    csv_data = list(csv.reader(csv_string.splitlines()))

    # 格式化处理：去除引号，添加方括号
    formatted_data = [[field.strip('"') for field in row] for row in csv_data]
    formatted_string = str(formatted_data)

    return formatted_string

# 示例CSV字符串
csv_string = '1, "John Doe", "john@example.com"\n2, "Jane Smith", "jane@example.com"'

# 格式化CSV字符串
formatted_csv_string = format_csv_string(csv_string)
print(formatted_csv_string)

[[1, John Doe, john@example.com], [2, Jane Smith, jane@example.com]]
