python 读取.csv文件

要在Python中读取.csv文件，你可以使用pandas库或csv库。

使用pandas库的方法如下所示：

import pandas as pd

# 使用read_csv()方法读取csv文件
df = pd.read_csv('file.csv')

# 打印数据框
print(df)

使用csv库的方法如下所示：

import csv

# 打开csv文件
with open('file.csv', 'r') as f:
    # 创建csv读取器
    reader = csv.reader(f)

    # 遍历每一行数据
    for row in reader:
        # 打印每一行数据
        print(row)

请注意，如果你使用csv库读取csv文件，你需要手动处理列名和编码问题。而使用pandas库可以更方便地处理这些问题。
