将csv文件的前两行打印到标准输出

import pandas as pd

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

# 打印前两行
print(df.head())

import csv

# 读取csv文件
with open('file.csv', 'r') as f:
    reader = csv.reader(f)
    # 打印前两行
    print(next(reader))

const fs = require('fs');
const csv = require('csv');

// 读取csv文件
const file = fs.readFileSync('file.csv', 'utf8');
const records = csv.parse(file, { columns: true });

// 打印前两行
console.log(records.slice(0, 2));
