使用wrie对象创建csv文件信息

python 复制代码

import csv
import random


# 按行写入数据
outputFile = open("319.csv",'w',newline='',encoding='gbk')  # 打开csv文件，指定编码GBK
outputWrite = csv.writer(outputFile)  # 创建一个writer对象
outputWrite.writerow(['序号','姓名','书籍'])  # 写入行使用list列表
outputWrite.writerow(['1','孙悟空','西游记'])
outputWrite.writerow(['2','白骨精','西游记'])
outputWrite.writerow(['3','张飞','三国演义'])
outputWrite.writerow(['4','曹操','三国演义'])
outputWrite.writerow(['5','马谡','三国演义'])
outputFile.close()  # 关闭文件


# 按行输入随机数，每一行输入6个随机数
numbersFile = open("numbers.csv",'w',newline='')
numbersWrite = csv.writer(numbersFile)
numbersWrite.writerow(['随机数','1','2','3','4','5','6'])
row = int(input("请输出行数"))  # 输入产生随机数行数
for i in range(row):
    a = i + 1  # 序号
    b = random.randint(1,10)  # 随机数1~10
    c = random.randint(1, 10)
    d = random.randint(1, 10)
    e = random.randint(1, 10)
    f = random.randint(1, 10)
    g = random.randint(1, 10)
    numbersWrite.writerow([f'{a}',f'{b}',f'{c}',f'{d}',f'{e}',f'{f}',f'{g}'])  # 将随机数插入文件

numbersFile.close()
