用 Python 读写

CSV（逗号分隔值）是一种用于存储表格数据的简单文件格式，例如电子表格。这是如何在 Python 中编写和读取数据的最小示例。

将数据写入 CSV 文件：

import csv
data = [["Ravi", "9", "550"], ["Joe", "8", "500"], ["Brian", "9", "520"]]
with open('students.csv', 'wb') as csvfile:
    writer = csv.writer(csvfile, delimiter=',')
    writer.writerows(data)

从 CSV 文件中读取数据：

import csv
with open('students.csv', 'rb') as csvfile:
    spamreader = csv.reader(csvfile, delimiter=',',)
    for row in spamreader:
        print("Name: {} class: {} Marks: {}".format(row[0], row[1], row[2]))
output:
Name: Ravi class: 9 Marks: 550
Name: Joe class: 8 Marks: 500
Name: Brian class: 9 Marks: 520
