python3 で csv ファイルを読み込んで、最初の数行を表示する方法

以下の例では、空の配列 data を用意しておき、最初の3行を読み込んでおく。

例

import csv

with open('data.csv','r') as csv_file:
    csv_reader = csv.reader(csv_file)
    data = []
    for row in csv_reader:
        data.append(row)
    for row in data[:3]:
        print(row)

data.csv

"2022/03/08 12:20:32","USD","売り","9876"
"2022/12/31 18:07:55","EUR","買い","1,234,888.9"
