python - 无法返回整个 CSV 数据框

Question

当我运行下面的代码时，我只得到 CSV 文件的第一行(我的名字行)。我该怎么做才能确保下面的代码返回我的整个 CSV？

import csv 
import pandas as pd

import numpy as np

def open_elves():

    with open('elves.csv') as csvjawn:
        readCS = csv.reader(csvjawn, delimiter = ',')
        for row in readCS:
            return row                
x = pd.DataFrame(open_elves())

print (x)

Answer 1

使用Pandas api提供的read_csv函数

df = pd.read_csv('elves.csv')
