CSV模块:尝试使用字典编辑行时二进制与字符串的问题

import csv

with open('data.csv', 'r', encoding='utf-8') as file:
    reader = csv.DictReader(file)
    for row in reader:
        # 处理每一行数据
        pass

import csv
import io

# 假设有一个包含字典行数据的列表
data = [
    {'name': 'Alice', 'age': 25},
    {'name': 'Bob', 'age': 30},
    {'name': 'Charlie', 'age': 35}
]

# 将字典行数据写入CSV文件
with io.StringIO() as file:
    writer = csv.DictWriter(file, fieldnames=['name', 'age'])
    writer.writeheader()
    writer.writerows(data)
    
    # 获取CSV文件内容的字节数据
    csv_data = file.getvalue().encode('utf-8')

# 从字节数据中读取CSV文件内容并编辑
with io.BytesIO(csv_data) as file:
    reader = csv.DictReader(io.TextIOWrapper(file, encoding='utf-8'))
    for row in reader:
        # 编辑每一行数据
        row['age'] = int(row['age']) + 1
        print(row)
