我在python中创建CSV文件时遇到问题

pip install csv

import csv

with open('file.csv', 'w', encoding='utf-8', newline='') as file:
    writer = csv.writer(file)
    # 写入CSV文件的代码

import csv

data = [
    ['Name', 'Age', 'City'],
    ['John', '25', 'New York'],
    ['Alice', '30', 'London']
]

with open('file.csv', 'w', encoding='utf-8', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(data)

import csv

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