分别编写读写csv文件和TXT文件的代码

在Python中，我们可以使用内置的`csv`模块处理CSV文件，`open()`函数用于打开文本文件（包括TXT）。以下是简单的读写操作示例：

**读取CSV文件:**

import csv

def read_csv(file_name):
    with open(file_name, 'r', newline='', encoding='utf-8') as file:
        reader = csv.reader(file)
        for row in reader:
            print(row)

# 调用函数，传入你的CSV文件名
read_csv('example.csv')

**写入CSV文件:**

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

# 示例数据，data_list是一个二维列表
data = [['Name', 'Age'], ['John', '25'], ['Jane', '30']]
write_csv(data, 'output.csv')

**读取TXT文件:**

with open('example.txt', 'r', encoding='utf-8') as file:
    content = file.read()
    print(content)

**写入TXT文件:**

def write_txt(text, file_name):
    with open(file_name, 'w', encoding='utf-8') as file:
        file.write(text)

# 写入文本到文件
text = "Hello, this is a sample text."
write_txt(text, 'output.txt')
