使用 python 写 csv 测试数据示例 2021-10-14

python 3.9

#! python
# -*- coding:utf-8 -*-

import random
import time

f = open("test_data_v1.csv", "w", encoding='utf-8')
ret = f.write("id,a,b,c,d,e,f,een")

for num in range(1, 12000):
    timeval = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
    number = random.randint(1, 22)
    backNumber = random.randint(0, 8)
    operator = "姜**"
    operatorCode = "02"
    if num % 4 == 0:
        operator = "楠**"
        operatorCode = "F03"
    elif num % 3 == 0:
        operator = "李**"
        operatorCode = "F04"
    ret = f.write(str(num) + "," + str(number) + "," + str(backNumber) + "," + timeval + "," + operator + "," + operatorCode + ",婉**,B01n")

f.close()
print("关闭文件成功！")

上万条非常快。
