從 Node.js 讀取 CSV 文件（用於使用 python）

Question

我正在嘗試從 nodejs 讀取 csv 文件，就像我對 python 所做的那樣。

這是我的 python 代碼

#!/usr/bin/python3.7
import os
import time
import pandas as pd

from pathlib import Path

addresses_df = pd.read_csv(
    'snapshot.txt',
    header=None, names=['id', 'address', 'balance']
)

for row in addresses_df.itertuples():
    print("Address:",row.address,"Balance:",balance)

這是我的 csv 文件

0,0x843fd22c88d59e57ae1856a871a5d95e95b0a656,52500000000000

提前致謝。

嘗試這個

const fs = require('fs')
const fastCsv = require('fast-csv')

fs.createReadStream('test.csv')
    .pipe(fastCsv.parse({ headers: false }))
    .on('data', row => {
        const [id, address, balance] = row
        console.log('address: %s, balance: %s', address, balance)
    })

output

address: 0x843fd22c88d59e57ae1856a871a5d95e95b0a656, balance: 52500000000000
